    Looking at that huge ass heatspreader i'm definitly gonna delid it when i get mine next week. I think it's the best cpu to do that with. Derbauer got 20C. Lapping just seems to be more work than delidding for less temperature gain.

    I know you’re not going to see this but I tried the Kingping extreme, Arctic MX5 and now Kryonaute extreme on my 7950x and nothing can drop it even 1c and all cinebench are within the same results at 38100 -/+ 50

    I would suggest anyone flat lapping for the first time to use the same flat surface (start to finish) and super cleaning between swaping grit numbers. It will take longer but it will come out near perfect

    I bet that heatspreader dust is great for the lungs

    I think if you had measured the cpu before and after grinding and lapping with a micrometer or vernier caliper, you could turn down the standoff height the same amount to compensate using a lathe and you could have used any cooler on the chip with the proper pressure (You would have to keep the shorter standoffs with the chip after modifying it)

    Pro Tipp Jay: Use a mirror instead of tempered glass. A mirror is much flatter than any normal plain of glass since you would see any curvature of the glass in the reflection of the mirror as a distortion. Thanks to that mirrors are almost universally the flattest object in everyone's household.

    If you want it really shiny, just wet sand with progressively 1000, 3000, 8000 grit.

    Jay, the next time use a figure-8 motion to help eliminate the pressure difference. Also, count the number of passes, turn the CPU 90- degrees and continue turning until you do a full 360. Again, this helps in eliminating pressure differences.

    jay you've been making some great videos recently. feels like old times

    It's honestly amazing how much of a difference sub-millimeter tolerances make. I'm so happy I don't deal with anything that precise.

    Thank you so much for shaving it down, THIS is the kind of test I wanted to see after the debauer-delid

    Jay figuring out you can reuse original hardware is the gem of info in this video. So flippin cool

    Would be interesting if you go to the lowest lapping possible before you delied it. :)

    Next time you replace the belt grinder you should get one that has the vertical disc plate grinder and rest plate. Makes that job a whole lot easier. 👍

    Thanks for another great video, Jay. Just wanted to share this. I have a 7600x (liquid cooled, Gigabyte B650 board) and can achieve 5.45 ghz all core @ 75~80 deg C using PBO negative curve offset and +200 on boost. Power settings are "eco mode" (88 watts max). 5.5~5.6 ghz single core. These are amazing cpus if you understand settings and have good cooling. I'll be lapping this week as long as the standoffs allow it.

    If you wanted to measure the gap between the cooler and the CPU I suggest using plasti-gauge.

    Thanks for the video. That was a really detailed comparison with lapped vs non lapped performance with a 360 aio. Im interested to see if direct die improves it any further

    Jay, it would be really great to see a comparison of the Ryzen 7900 vs. the 7900x at 65w ECO mode. Which one performs better in productivity work?

  • BurningGlory

    It would be interesting to do with with a proper mill. Something that could guarentee precision and levelness.

  • Julian Klappenbach

    I just had a thought: for tightening those screws down on the CPU, would a torque wrench with extremely small resolution be helpful?
