    Another PSA: Cavitation isn't happening in your CLCs/AIOs. The motors aren't that powerful, you'd need to go to industrial applications for that. Cavitation is when water vaporizes on the surface of an impeller, which isn't happening in these hobbyist-level motors. With cavitation, air isn't in the voids formed but water vapor is. With CLCs/AIOs, it's just air bubbles getting pulled through the loop (not cavitation).

      What would also be interesting is testing the optimal aio orientation , top or front and how cpu and gpu temps are affected by it.

      Why not just fit a hygroscopic automatic bleed valve and solve the air problem? Can mount it in any orientation then.

      @Gamers Nexus: THANKS! This Video solved my Headaches I had for Days!! I have a Enermax Liqtech 120X AIO in my system for around 6 Years and it worked pretty well, until recently the CPU got very toasty up to 100C° w/o even exeeding 10% load. I tried a lot of thing cleaning evrething up specialy the radiator, placed in the back of the case the only place I can put it, putting new fresh thermal paste on the heatsink, with dual 120mm Push/Pull Fans it properly can be somewhat warm in the case it's a Big-Tower completely silenced with Foam Padding 7 3.5" HDDs with an i7-4770K and the system runs very often 24/7. To my excuse all the documentations/manual I had and reviews tests I have seen + read, when I chose the AIO, shown the Radiator placed with the tubes UP installed and it fit very well in my case and let a lot space compare to an big air cooler and it was the only way it fit with the GPU installed in the first PCIe 16x slot. I got slightly desperate and was prepared to buy a new AIO because I don't want to go back to an air cooler. After a lot of research in the web I saw this video and tried my last ditch attempt and put the GPU on the second PCIe 16x slot and reversed the radiator with the tubes down, DANG! the Temps dropped literally 40% and everything runs smooth maybe not like on the first day but OK 👍.

    • Greymane_Gaming

      @jazzochannel yes on the ambient air temp...
      I live in a location with cold winters and hot and humid summers... the major difference in my PC cooling is my room's temp.
      As a welder, I am used to being hot and a 90f room is okay with me... my old PC however used to overheat constantly with air or liquid. Kicking my room's ac unit on stopped it.
      That being said... I have just bought a new h100i lc specifically because I like the lower profile and had the extra few bucks... but if the cpu had come with an air cooler, I'd have used that instead and saved the cash because the difference between the 2 for me was only 2-3c at ambient/uncontrolled room temps... and too hot is too hot when it's tripping the thermal protection of you system.

    • jazzochannel
      jazzochannel 2 months ago +1

      @Johnny Flech yes. that's who i'm talking to. AIOs are a massive gimmick with marginal benefits over air cooling. custom pc-liquid-equipment is an overpriced niche marked. also not worth the effort or the cost imo. it's all very overpriced, very "elitist" equipment that gives the user 5-10 more FPS in a game or completes some task in 275 minutes instead of 295 minutes, lets say. The performance you gain from using these products vs the price and time to set up is for the most part not worth the effort - but that's a subjective judgement and it depends on how you value your time.
      don't even try to play the "enthusiast" card with me.
      "PC temps do not exceed 90°C ever" Sounds like you haven't lived in a area where ambient temp is 35-45 C and you're trying to compile or render some project that takes more than 60 minutes.
      Note this: liquid and air cooling is equally useless if the ambient temps are high. they are equally dependent on ambient temps.

      @jazzochannel this is for people wondering if mounting an AIO with tubes up will affect their pump.
      My NZXT X63 has been mounted in an H210i for the past 3.5 years and has not exhibited any pump noise or had any issue at all. The pump is mounted tubes down and radiator is mounted with tubes up. PC temps do not exceed 90°C ever and it sits in a cool room.
      You mileage may vary depending on your parts i.e. if you have an overclocked r9 5950x running at Tjmax your AIO will run hotter for longer resulting in higher fluid evaporation / less fluid getting to your upside down radiator which in effect will cause pump noise.
      Parts:
      NZXT H210i
      NZXT X63
      Aorus B450i
      R5 3400G
      NVMe SSD

    I’m surprised I haven’t seen any manufacturers with their tubes half way up the rad. Where the fluid enters from half height, goes to the top of the rad, all the way down, and half way back up before returning back to the tubes. This would allow the rad to be installed in any direction plus likely provide GPU clearance.

      I kinda did this anyways - I have a cube case itx build with a 120mm AIO front mounted, and so instead of 'tubes on top' or 'tubes on bottom' I am looking at 'tubes on left' or 'tubes on right'. Highest point in the loop is the logo side of the radiator. Since the cooler in question is an older NZXT M22, bought at a fair markdown ($50) . That was one of the first pump in radiator designs, so the pump isn't the lowest in the system regardless.

  • Jarrett Hobbs
    Jarrett Hobbs 2 years ago +349

    Unfortunately, front-mounted, tubes-up is often the only way a particular liquid cooler will fit it a particular case, either because there aren't appropriate mounts anywhere else and the tubes are too short for tubes-down, or because there's an issue with clearance related to the motherboard or the RAM that prevents mounting it in the top of the case.

    • phunyguy
      phunyguy 23 days ago

      Asus Tuff Gaming mATX case/motherboard/280mm AIO also suffers this same issue. Cannot top mount, RAM in the way, and front mount can only go hoses up because the (riveted in) PSU shroud is in the way. Woe is me. I keep getting water noises a few times a day, like a trickling noise from it shuffling some air around, so probably need to replace the chassis before I have to replace both the chassis and the AIO.

    • The Firehawk

      @Gamers Nexus There's also a tradeoff to be had here, shorter tubes = less permeation, it might be worth it.

    • Annie Worroll
      Annie Worroll 7 months ago +1

      @Mike Wazowski If you have to run it in a front mount with the tubes at the top, then yeah, mount it as high up as possible. It may not be ideal, but it's better than nothing.

    • Mike Wazowski
      Mike Wazowski 9 months ago

      @Gamers Nexus if the pump is sllllllightly lower than the top of the radiator, is that okay?
      Also if I have top mounted AIO is it better to have the front fans pulling in or pushing out?
      Currently I have a Meshify 2 with rad at the front sucking in and fans up the top and rear pushing out.

  • Robert Vickers
    Robert Vickers 5 days ago

    at 5.30 you say the rad is split 60/40% > inbound/outbound... this would mean that by volume (with barbs down) would have to push the water up over the separation plate, where with barbs up the water in the outbound side would be at a higher level than the inbound forcing the water up to the outlet barb and any bubbling and gurgling would likely be the water coming in and not a problem at all. this would mean that you want the air to be trapped at the radiator inbound barb so you want the barbs at the top of the rad? would this not make your video the wrong way to install a radiator?

    The pump for almost any cooling device whether it be a pc or car should be below the highest level of liquid, this ensures that liquid is constantly being flowed through the pump due to height and gravity. Dry running pumps can cause many problems and eventually cavitate them.

    • einherz
      einherz 22 days ago

      in any way pump and temp will separate dissolved air. for avoid that, cool agent must be warmed max as well cooler itself and only in that condition it must become watertight

    • Jonathan Roberts
      Jonathan Roberts 6 months ago +5

      Well put. I think 3 minutes of this video could have been omitted by just simply saying “make sure that the afferent line to the pump is being fed by a reservoir that definitely has no risk of air accumulation - being below the fluid-air level.”

  • Kushal Prasad
    Kushal Prasad Year ago +104

    This is super-useful and intuitive in retrospect. I recently cleaned my pc and ran into high CPU temp errors afterwards (probably shifted air around). I was about to dump my AIO and thankfully came across this gem of a video. I had a front mounted radiator with the pump being barely above it. Switched to top mounted configuration and now my CPU runs cooler than ever! Thanks GamerNexus for once again!

  • Scott

    One problem is that most 360mm AIOs tubes aren't long enough to front mount with tubes at the bottom of a mid-tower ATX build, especially with a long GPU. The only ones I have found are the ID-Cooling 360s. They have 465mm tubes, the rest mostly have 400mm tubes or shorter. I flipped mine over after seeing this, luckily they were long enough.

  • Benjamin Williams
    Benjamin Williams Year ago +5

    The problem with radiator front mounted with tube down is the video card length gets in the way causing a bend in the tubes making them shorter.
    Mounting the radiator at the top of the case has limits as not all cases can accommodate top mounting a triple fan cooler.
    If the case does than to give better cooling a fans setup in a push pull method is best. Or a pull setup as an option. A push method causes back pressure restriction as the fans have to push the heat at the top of the case through the radiator fins and the case holes which by design are small.
    In any case that I've had to mount AIO Coolers I've taken time to mark out All of the holes that the air will be passing through the radiator and out the correlating case holes and drilled them out two drill bit sizes bigger than the case hole size.
    It's a lot of work but after filing and paint touch up the top mounted AIO's mounted in push, pull, or push pull breath a lot better.

  • Nicolas GUILLAUME
    Nicolas GUILLAUME 11 months ago +2

    Awesome video, would have been interesting to see what it looks like when the AIO is on the side next to the CPU where half of each reservoir is above the pump. I'd guess it's not ideal Since you might lose a bit of the cooling capacity if there is enough air.

  • Cassidy B
    Cassidy B 6 months ago +36

    The problem I find is the tubing on these AIO coolers is nearly always too short to mount them properly with the tubing at the bottom of the radiator as described in this video. If the manufacturers would just make the tubing a bit longer this might actually be a possibility, but pretty much every build I've done that isn't top mounted has to be upside down due to the pitifully short length of tubing provided on these units.

The hoses are too long for the mesh 2 case I have by Lian Li. So they look ridiculous, bit annoyed by that, but it's by corsair, the liquid ice 3 fan rad

    I've been looking everywhere for the answers that literally only this video provides. I'm building with an AIO for the first time in two days. I did so much research and was convinced until this moment that tubes up vs tubes down didn't matter for front mounted radiators. I'm so relieved to have GN finally provide a definitive answer on this, yet pissed that AIO has been around for God knows how long and only now is there a correct answer floating around as to how you're supposed to mount your shit.

    • Maxik

      It is a marketing trick. Manufacturers want you to buy their coolers more often by improperly mounting it and shortening the longevity of coolers. The faster it degrades, the sooner you have to buy another one pushing their sales up

    Thank you for this extremely informative video before I install my liquid cooler. How do we feel about a 120mm square radiator being mounted with tubes on the side rather than the bottom? Based on this science, it seems that it would function at least just as well as tube on the bottom since both tubes would still be totally submerged where they meet the radiator.

    Anybody ever think of increasing the cooling CPU surface by doubling heat conductive sides? Stand the CPU on it's side.
    You don't have to cram things tight, anymore .. Perhaps you can use your mind to do it another way.
    You can even make a hollow cube out of the processor and get at least 5 sides of conduction; circumventing the lost time of length, and standing waves or crosstalk.
    Or "possibly" make a hollow open square tube and have 8 sides of conduction. I don't know if these designs will affect speed or bring in the problem of stray capacitance. .

    Great video, but how does it effect the AIO units where the pump is situated in the middle of the radiator? Because the pump will always be drowning in the coolant. Does it still matter whether the pipes is on top or bottom? I understand it's even the same as a car engines where you want the engine(heat source) drowned in coolant and slightly below the rad.

  • Smasher Devourer

    Wouldn't curving the tubes so that they are lower than the top of the radiator technically trap the air in the radiator? If air moves to the top, wouldn't it not be a stretch to assume that the air wouldn't go down the tubes and then up again? Particularly if the pump isn't really strong enough to move air?
    Asking because this is the only way I can install my radiator...

      802 Garage 2 years ago +1

      @Skelath All the other noises you are referencing have water being added to a system rather than a closed system. In a large contained system where droplets can form and fall, your other theories might stand. Inside of heat pipes there is no room for the liquid to form droplets and fall onto an open surface. It will basically condensed on the sides and slide back down. Otherwise there is very little movement in the system.

      @ytilanigiroon Also to further elaborate thermal heat pipes use capillary action aka it's the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity.
      During operation of a heat pipe, heat supplied to the evaporator vaporizes the working fluid, which travels down to the condenser. The vapor condenses in the condenser, and the liquid is drawn back to the evaporator by the wick, using capillary forces.

    Thank you for enlighten us, and huge thanks for making this video. You are totally awesome. I almost thought I need a new cooler but following your instructions saved my pc. flipping and putting pump pipes lower and keeping the radiator its position upper then pump and saved lot of noise. Surprising is that, last 12 years I had Radiator pipes up never got any issues but when started cleaning my pc and I added new thermal past and plugged it back same as before nothing changed, suddenly its started making very loud bubble noise and my pc temperatures where very high up to 80C in min and also got shut down by its self, I wasn't sure what's happening. I thought Its time for new cooler but luckily I watched your video followed your instructions solved my problem straight away, I still little spectacle about it, slight small noise hardly I can hear and my CPU temp is back to about 32-38 that's awesome. (I kept the radiator pipes down and whole radiator higher then the cpu pump).

    If you guys are in a predicament where your water block HAS to be at a high point than your radiator I suggest getting an AIO with a decoupled pump separate from the water block, like Be Quiets Pure Loop and MSI’s aio

    Sadly most AIO's have short tubes and mounting them "correctly" isn't viable, specially with a big hardware piece that you didn't mention in the middle, the GPU. In my case for example if I mount the AIO like you say the tubes are stretched as far as they can go and they push against the GPU, putting a ton of strain on the PCI-E. I agree with the testing but most of the time that's not viable in a real use case. Maybe companies should make AIO's with longer tubes.

    • Gurvinder Parmar
      Gurvinder Parmar 2 years ago

      @soccerguy2433 the temps of the CPU is always significantly higher when your radiator is at the top of the case...this has been tested and proven multiple times already. The fans on your radiator are usually pushing air out of the top of the case...the air being sucked from the case is directly coming from the GPU fans which is hot. Your pump may be better with the rad up top but your definitely not getting the best performance by using it that way. The difference is like 10-15c so it's not small. My setup has the radiator in the front with the 3 fans pushing air through it. The 3 fans up top and my rear fan are all blowing fresh air into the case. I've consistently gotten the best CPU temps running the AIO and fans this way. It's 4 fans acting as intakes and 3 fans acting as exhaust. The hot air being pushed by the GPU is not in a direct path to the radiator so temps are much lower. I'm not disagreeing with this video. The pump is probably best off with the rad on top. It's just not optimal for performance.

    • soccerguy2433
      soccerguy2433 2 years ago +2

      @Gurvinder Parmar that has nothing to do with heat rising, like GN said: the air in your case is moving and flowing and basically mixing the air. the air inside your case is going to be hotter. that hotter air can't take heat out of the radiator as well as the cold air you're intaking from the front.

    • soccerguy2433
      soccerguy2433 2 years ago

      i'm in the same boat: Sucks for me because I still have a cdrom drive at the top front of my case. That means I have to mount my rad down low. Because it's down load, the Barb's have to be at the top so my pump can reach the CPU. This also means my pump is the highest part of my AIO loop.

    • FirebrandX
      FirebrandX 2 years ago

      @Master Daedalus Depends on the CPU. If you're running something like a Threadripper or Ryzen 9 3950X with overnight chess engine analysis, you'd need one gigantic air cooler. An AIO will fit quite nicely and not stress the mobo with all that mass. I switched to an H115i Platinum and it works great, though I did turn it upside down as per this video to get rid of the occasional water trickling noises.

    And why the heck would anybody use a cpu cooler fan to blow hot air IN to a case, it's bloody backwards 😅😆 Wise up 🥴
    Oh yeah, about the cooler position around 18:03 Maybe NZXT had it exhausting to the front, and the back / top fan is intake? Sure it's odd, especially because mounting at the top or back for exhaust is better, but hey, each to their own I suppose.

  • Sum41rthe1
    Sum41rthe1 11 months ago

    You mentioned it might not be the coolest as you have to exhaust. You can easily put the radiator fan closest to your intake fans as intake too. It is mostly pulling in cool air with the other case fans, while the fan furthest is set to exhaust (this is for my 240mm aio and running cinebench stress tests I didn't hit more than 68c)

    I have had my AIO running for 7 years now. Name brand don't remember which one exactly but ones perfect to this day. Glad I mounted it with radiator on top blowing out. Single 120mm fan and temperatures are still the same as when I installed it. Also the case is a popular Lian Li almost 20 years old with all the original fans running. Goes to show if you maintain your system well they can last a very long time!

  • Gor Ky

    Sadly this isn't a conversation to be having with us Steve.
    Its a conversation you need to have with case manufacturers.
    No case should ever have the ability to mount a radiator in the wrong place - which would wholly eliminate 98% of bad AIO installs period.
    No more front mounting them as part of the intake like a fool.
    No more bottom mounting and fighting the heat by pushin down, or even worse another inlet.
    Top mount your rads in a case actually designed to fit one above the motherboard - or just don't bother - you aren't getting any value from what you've done.
    In fact you're literally taking heat from the components and blowing it back onto them - very clever and efficient, I mean nigh on absolutely pointless.
    5 degrees when the average CPU only ever hits 60-65C max is not worth $100.

    • gmu_alum08
      gmu_alum08 Year ago

      Sadly it's true. I have a Corsair 280mm aio and my average gaming temps are between high 40s to mid 50c. Rarely does it hit 60c. Maybe a 420mm aio will run even cooler like low 40s C best case scenario. Worst case you'll still end up between 60 to 65c but it'll take much longer to get there because more liquid volume=longer to heat saturation

    Steve, thank you for this explanation on the proper mounting for AIO coolers. It makes perfect sense. In My NZXT case, I mounted my lian li gallihad 3 fan radiator on top. It works very well and never hear it. The other thing about my nzxt case is that it has vents at the top of the case too so the hot air will easily escape. My case has three 120 mm fans in the front of the case pulling fresh air into the case. At idle the Cpu is at around 20 deg Celsius. Even under several pcmark benches, the cpu never got above 38 degrees Celsius.

    seems to me that once you have the part that attaches to the cpu you could just attach it to an aquarium pump outside the case. and since your using a better pump where orientation doesnt matter simply place the radiator inside the mini fridge sitting next to the computer desk or strap it to the side of a box fan, maybe drop the radiator all together and just cycle the flow from inside an actual fish aquarium. either way you save hundreds, regain space in the case and gain superior cooling even if you do little more than run the tubing to a 3-5 gallon water jug. or go all out.

    Great video, I am in to mechanics and understand vehicle radiators, and how the air travelles around the system always reaches the highest point.
    I have a corsair 4000d corsair suggest the 360mm radiator, to me suggests its an air free 100% liquid system, I was considering the 280mm because it fits at the top making cooling better because heat always rises.
    This video has helped me make up my mind 100% understanding they are not an air free sealed units, so the 360mm configuration is definitely not an ideal choice, like shown on the corsair site.

    I’ve tried to explain these exact properties to people , some don’t believe their own logic is fallible. Unfortunately science usually reigns true especially in these situations. Just because you can doesn’t mean you should , and issues can arise when going for aesthetics over logic. Which is usually the case when someone wants to argue over their highly inefficient loop runs to look nice , rather than an efficient loop style which is not so subjective depending on the style of components used. Knowing your components is very important as well especially with radiators and their specific applications some are better for high heat environments and some are not , vice versa on colder environments. Also you positioning of rads and fans and case circulation setup.

  • Outlet

    Your video was excellent and very informative. I was pleased to see that my installation was done correctly. (Small pat on my back.) I have never understood why these AIOs use non-transparent tubing. I would like to see my coolant moving thru the system. That way, I could see that the pump was working correctly and any air bubbles in the loop. Also, why do the manufacturers not include a separate reservoir in the loop? That would allow me to see two things: Any air bubbles are being expelled and knowing that the loop is completely filled. Maybe you could produce a video showing how to add transparent tubing and a reservoir to the AIO. I'm thanking EK here, but my PC came with AIO installed. Before you build that gaming PC, determine what you will place into the case to ensure that they will actually fit, width, length, and height.

    So... a lot of us are pretty much screwed then.
    I mean, if I mount my MasterLiquid ML240RS with the rad up front (tubes up), I'm basically introducing bubbles (and the gurgle noise, which happens but is not very common) into the top of the rad. I don't think I can mount it tubes down because of the GPU, but I'll try it tomorrow, and mounting at the top is possible, but I may not have the space to do push/pull the way I have it now.....
    It's also rather infuriating to think that, even though I have considered this before, there are no directions on this on pretty much any manual. In fact, it lead me to believe there was some unknown system built in to let air bubbles escape.....

    • Hussain Alqadhi
      Hussain Alqadhi 2 years ago

      Don't have push pull then, i think sp fans are good enough for push only. Then use those extra fans as intake from front where the aio used to be, then you'll have cold air entering from front, hot air exiting from top and back.

    I had a disaster last night with my aio, it's an uphere branded single fan aio rear mounted tubes down on a 3600, I don't remember buying it but I would imagine it being reasonably well reviewed/price was what lead me to it. I noticed that my idle temp has been getting higher recently and when I start ANY game fans immediately peg to 100% (sometimes even when it's idling and windows starts a background process it Ill stay at 100% for a little while...in my experience the thermal grizzly I used has been good for around 5 years so I was sceptical it was a tim issue but I reapplied it anyway. After reapplying in bios the fans pegged at 100% and the heat is climbing past 80 and despite doing the air bubble dance the pump (which was previously silent) is now screaming.
    After opening the loop by removing the cpu plate I found a heap of brown residue (no idea what it is) in the corner of the intake channel and the fins are covered in this slimy residue, after some cleaning with acetone first then a rinse with distilled water and refilling loop pump first (and more bubble dancing) it runs about as well as it did from new...this aio is 9 months old...
    Tl;Dr Despite what the manufacturer says these aio's can be user maintained and if you suspect degraded performance over time due to insufficient cooling I would advise getting some distilled water take the cold plate off inspect for residue and clean it out (if there is any) and by pulsing the pump and adding water you can refill the loop just remember that you will be adding an air bubble when you put the plate back on so you need to get that bubble back into the radiator...might save you buying a whole new aio

  • Local Man

    I just bought and installed my very first AIO at the weekend (it's a corsair capellix elite) I put the Radiator at the top with the fans as an exhaust. I know a lot of people say you should do the fans as an intake, but honestly I think this is better for me, as I heard it can help with cooling the GPU more. My CPU isn't that powerful tbh (an 11th gen i5)
    Also if I wanted it to be an intake I should have gotten the bigger Rad with the 3 fans and put it on the front of my case. My case is a Corsair 680x though, so has good airflow.

    • Dowlphwin
      Dowlphwin 7 months ago +1

      I always cringed at the idea of running radiator fans outside-in. Radiators are meant to dissipate a lot of heat, and blowing all that into the case seems stupid.
      Although it seems even newer graphics cards tend to suck air in, dunno. I guess the other components inside are less heat-critical and you can just blow air out somewhere else, but that would typically be the front, which can be problematic. And it could also be bad if you combined liquid and air cooling systems.

    Ok, so the goal is to get the air bubble(s) sitting at the top of the radiator away from the pump and away from the tubes.
    So ideally you want..
    1. the pump below the radiator

    2. the tubes attached at the top of the pump
    3. the tubes attached at the bottom of the radiator
    4. the tubes to run mostly vertically with no high spots where a bubble could sit

    Is that right?

And yes the boot up blub was removed, and no more gurgles.... And it even runs cooler, though that is very very likely to be mainly caused by the fact that while at it I removed the radiator's winter coat....
    What's even worse, I work in oceanography and know my way around turbulent flow... I should have known, but never actually thought about how to do it, just mounted it and it (kinda worked).

    Much appreciated Gamers Nexus, Absolute and Awesome information regarding AIO`S. Had i watched this earlier, my Msi AIO would not have died in six months. I'm now running a Cooler master AIO , mounted tubes down.

    This is easily fixed by redesigning how the tube interfaces with the radiator. Rather than going straight into the radiator, there should be a small pipe, with one end always submerged (imagine a drinking straw). That way, any air that gets trapped in the top of the radiator will not interfere with the suction back to the pump.

      It'll always get more air in it though, over time. I'd just fit a hygroscopic automatic bleed valve.

    The lengths y'all went to for the purpose of proving a pretty obvious point about AIO's is insane. You're all insane - I hope you know that. And that's why we love you.

    I'm an industrial pump mechanic, I can tell you right now when you seat the AIO improperly you're going to get air in the impeller, that causes cavitation(micro explosions of air), which will absolutely ruin any kind of centrifugal pump. Great video.

      @IIIrIpI7III This is all nonsense for clickbait payoff! Some of it is possible, but you need to buy a real shitty AIO...

      How would seating it improperly cause that issue?

      guys, a pump mechanic doesn't know about physics, and this isn't cavitation. the impeller would have to be spinning so fast that it creates a low pressure area strong enough to prompt evaporation in the coolant to cause cavitation. those evaporation pockets would then collapse like a rubber band being pulled back and snapped in a no-fucking-around effort to return to stable pressure. what's happening here is more like swishing mouthwash around, which doesn't displace molars over time.

      No way on this earth this scenario would cause cavitation. Cavitation IS NOT the mere presence of air/bubbles in the flow. Cavitation is what happens when due to low-pressure sessions (usually vortexes) the liquid goes to a vapor state (liquid's vapor pressure equilibrium) and right after the low-pressure session ends, the vapor transition back to liquid. That usually happens extremely fast which in turn generates pressure/shock waves. These shock waves are what, in turn, damages the structure.
      These little cute pumps are FAR from being able to generate these pressure shifts.
      That being said, the bubbles do cause all the harm described in the video. However, it's not due to cavitation, but rather due to all the reasons Steve correctly pointed out.

    Okay, so I watched the whole cooler video... Super-informative but the one thing I didn't hear (or don't recall hearing) was a definitive 'best' orientation. Simple question, top mount versus front mount (assuming tubes elevations are right) - is one better than the other? I'll toss in a request for a video too... you do a lot of case reviews, which are great. But I don't ever recall seeing one that focuses specifically on 'best cases' for water cool solutions. Having a water cooler changes so much... fan selection, noise levels... would be great to see best cases for AIO watercool.

    • Alex K

      Front is better. If tubes are long. If not, take arctic freezer 120 agd install on back exhaust. Top is 20-30% hotter because of hot air of you cpu.

  • Kent Eriksson
    Kent Eriksson 7 months ago +3

    There is also the question about what's best for the CPU, and that's not to mount the radiator at top as exaust. That will force all the hot air inside your computer through the radiator, instead of for example front mounting the radiator to blow in cold air from outside the case. There is no perfect answer to this. The GPU might also get hotter with a front mounted radiator, so I would say that top and front mounted is equally "right" or "wrong" if you will. I would choose to front mount the radiator just to get that could air through it, but at the risk of a hotter GPU. Top mounted, colder GPU, hotter CPU.

    • Murilo Perrone

      That's a good point. However, if the airflow of the case is good, then internal temperature should be close to the external temperature. If the air enters and leaves case properly, creating a good airflow, then it won't matter much if the radiator is doing a push (GPU priority) or a pull (CPU priority).

    in closed-loop hydronic plumbing system there are ports to release air and expansion tanks to deal with liquid expansion as it heats -- the idea being to eliminate all air from the system. it's as if the designers of these systems are completely unfamiliar with 100-year-old tech known to any plumber

      @biffwebster1212 no, it’s clear in the video you need to mount the radiator to the outside of the case, but on the bottom. The tubes should always be pointing out, but the fins on the reservoir need to be oriented in such a way that the pump is under the bottom of the top of the loop.

      @Infinite Blaz I have my AIO top mounted in my O11 EVO.. My fans are set to exhaust. My temps are low.. the only thing I experience is my coolant temp gets to about 40c under full load. And that's only when its hot outside and my AC isn't on. Right now I have RD2 running in the background and my coolant temp is 38c..my AC is on in my room and I'm good. GPU is a Strix 3090 that is consistently 82c and my CPU is a 5950X at 76c. . No problem top mounting.

    • biffwebster1212
      biffwebster1212 6 months ago +2

      @Ocean Bytez what are you even talking about? We're talking about air inside the cooler. If your pump is higher than your radiator then air in the cooler will find it's way in to the pump and stay there. This will cause your pump to die faster and also have negative effects on the cooling. Nobody is talking about case temps. Please don't talk to me if you don't even know what we're talking about.

  • ChaosContrl
    ChaosContrl Year ago +12

    Big question though: if I understood correctly, you want the pump in the loop to be positioned as low as possible. What if the pump is located inside the radiator, like in the MAG CoreLiquid 360R from msi? Should the radiator still be positioned at the top of the case?

    reminds me of the days when I ran a custom loop (long before AIOs were even a sparkle in the inventor's eye) and I had a reservoir+fill port with beads at the highest point (and to capture air bubbles)

  • Ronnbot

    I've been using a Corsair H50 for more than 10 yrs on an over locked i5-750 with no problems because it's properly mounted - barbs at the bottom and pump below the middle (let alone top) of the radiator.
    Granted it hasn't seen a lot of use for the past few years but still.

    Edited to include that this TLDR is just a quick recap for those who have watched the whole video and have a full picture understanding of the reasons why and why not.
    I STRONGLY encourage viewers to watch the whole video and the follow-up (clip-share.net/video/tU7D6y_QYcI/video.html) and not to start panicking about their set-ups. Apologies to Gamers Nexus and everyone for any misinformation this comment might have caused.
    TLDR:
    Top-mounted radiator: Yes
    Front-mounted radiator: make sure the tubes are coming out from below, not the top and make sure the pump is below the highest point of the radiator.
    Bottom mounted radiator: don't. just don't

      @Gamers Nexus that's not the issue. The video was very unclear. You needed to post pictures of proper installations at some point. I still dont know what that looks like.

      @Super Anderson TV I didn't know it was considered a crime to ask for the information to be a little more condensed. Call me whatever you might but I'm not willing to sit through 10 minutes worth of someone flapping their fucking gums on the most monotonous fashion imaginable, just to arrive to the gist of the problem I'm looking for help to solve. There's fanfare, and then there's bloody lulling you to sleep. This channel falls squarely into the latter. So maybe instead of bemoaning me for making a passing comment, you could make an effort to understand why I even made it. It's not hard.

    I installed Corsair H100 in 2012 with the top of the radiator at or near even with the pump. I have had no issues with the system.
    Watching this; I have been blessed that this configuration has run as long as it has.

  • Stephen Partridge

    Interesting video, how about a system where the radiator is mounted with the tubes at the side with both tubes above the pump?

  • Craig Newcomb
    Craig Newcomb 2 years ago +9

    It would be nice for the companies to make the tubing a little bit longer to be ABLE to put it in the right fitment. I bought the ARCTIC cooler and I was easily able to mount the tubes at the bottom. Couldn't do that with the Corsair H100i that I used to have.

  • Vince Phoenix
    Vince Phoenix Year ago +5

    Not sure about something : what about the processor side ? Should the tubes be at the bottom, or the top, or is it ok as long as the tubes go down from the cooler mounted topside ?

    • Philip
      Philip 7 months ago

      If the processor is located below the top of the radiator it doesn't matter, so long as your tubing doesn't go above the top of the radiator (and if your tubes are coming from the bottom of the rad I highly doubt you physically have enough tubing for this to happen).
