    Nice, that should alleviate some of the idle temps.

    It does make a huge difference, especially if you want the fans to stay low.

    Rarely when the laptop boots it will ignore the BIOS set OC and will boot with turbo boost disabled. Have to restart or shut off/turn on to have correct cpu clocks.

    It seems to affect 9900K aswell.

    Not to mention that sometimes (1/20 ) during boot it does not even detect the ADATA Sata3 SSD with the windows 10 until I completely power it off and on again ... this is a BIOS issue which is not fixed yet even in the latest bios.

    Had a 8700K and delidded 2 times. After 2nd delid I got good temps. With 28C ambient temp I got 80C max in Fire Strike for CPU temp with 4.6 Ghz all core. However I wanted even better so I wanted to delid again to change the factory installed IHS to a copper one.
    However during my 3rd delid process the CPU died.

    Regarding temp/performance what would you guys recommend? Another 8700K or a 9700k?
    I tried a delidded 9900K in this chassis and this cpu is a no go for this laptop. 1 power brick is not enough and can not hold 4.7 Ghz during a Cinebench run and core ratio will jump all around between 3.6-4.7 Ghz. Tried 4.6 Ghz with undervolt and that is stable, however it was just too hot for me.

    What CPU would you guys buy?
    There are 3 things that are important for me:
    - more FPS
    - less or no microstuttering at all
    - lower temperature with same settings

    There are 3 CPUs on the list which I considered:
    - delidded 8086K USED for $335
    - brand new 9700K for $410
    - brand new 8700K for $420

    I watched comparison videos on Youtube and with same settings 8700K beat the 9700K in Fire Strike and in 1-2 games, however in almost every tested game the 9700K performed same or better than the 8700K. Regarding temps they were same or lower however these tests were performed in desktops with AIO cooling so they dont really represent the temperatures in a laptop.

    With stock settings how does the 9700K perform in a P775TM1-G chassis paired with RTX 2080? Can it stay under 80C in Cinebench R15 or due to the outdated manufacturing process it is running as hot as a 9900K and the P775 is struggling to cool it down so I should just got with a used 8086K ?

    Did it just refuse to boot with the custom ihs? If so did you try again with the stock ihs?
    Sometimes the copper ihs is too thick and adds too much pressure, resulting in some of the pins not making contact.

    I had both 8086k and 9900k in my p775tm1 with a single 330w brick and a gtx1080. You do need a decent undervolt to hold 5.1Ghz for 8086k and 4.8Ghz on the 9900k from my experience. Did you have the PL1/PL2 and VR Current Limit raised?

    As for CPU recommendation, if you can find a used binned 8700k/8086k, that'd be my go to for the p775tm1.
    It's just hard to make a good argument for the current R0 9900k.

    Loving my 8086K. The average 8700K requires quite a bit of voltage to hit 4.8Ghz. Some people have GEMS though and they are certainly great chips if you have a good one.

    But, I can put out less power at 4.7Ghz With my 8086K than a 8700K will at default speeds usually.

    My 8086K runs 4.7Ghz like it’s nothing. It never throttles or downclocks from that either.

    I can also run 4.8Ghz or even 5Ghz fairly easily. But I’ve gone back to standard thermal paste and Battlefield V really pushes a CPU harder than any stress test I have.

    I think 4.7Ghz with a -0.180 undervolt is the sweet spot for me.

    The stock IHS is copper by the way.

    I broke a 6600K after multiple delids. The first delid was good, and I resealed the lid back on with white cauk used for sealing around toilet bowls. It ran excellent for a while at 5.13Ghz which was incredible for a 6600K i5. I originally purchased it from Silicon Lottery as a (4.8) bin version.

    But I delidded again and again and eventually killed the thing.

    Yes, that's why it has a silver appearance, but it does not impact the cooling really.
