    thats a beauty, 40% auto fan at only 68C is pretty nice, how much of an improvement do you think it helped? at 40% auto fan

    Thank you.
    Just to confirm; that's 40% fan speed on the U3+ fan mod, that consists of 3x FF5 120mm Vardar fans running at 1100-1200RPM when on 40% power and the Clevo dash is set to "Automatic" fan setting.

    I think the "automatic" or "overclock" Clevo fan menu settings, is an unfair test. Because the CPU and GPU fans come on and work separately/independently depending which hardware reaches a certain amount temperature point. This cools down the overall heat on the whole heatsink that are attached together. This is why the "full" fan settings through the Clevo dash is more accurate for test on max temperatures IMHO.

    The .925 silver IHS only helped me by 1-2c I think. It's not that much of a difference, but I loved the experiment.

    I'm now trying to get a p870km cpu heatsink (or maybe the new Coffee lake) to see if I can create it in piece's of silver, then build it up. If I do, then I will make sure its a bareback heatsink, meaning the CPU lid has to be removed and the 1151 clamp to be down on top of the CPU by using some kind of housing. This will improve temps big time I think.

    I'm turning this into a hobby lol.

    .999 Silver heat spreader lid, is now going through its initial setup process. This is 1.1mm thicker than the Kaby Lake lid to fill in the P870 heatsink gap. This is also Coffee Lake compatible too. The small hole is for anyone who wants to turn it into a necklace afterwards :cool:

    The Coffee Lake die is slightly bigger than the Sky Lake and Kaby Lake dies.

    That's about the extra size the two extra cores take. It's still mostly IGP in size.

    I always wondered how much of a big thermal difference the IGP makes to the overall CPU Temperature.. I know that the 7740X has no IGP, but it has a base clock of 4.3Ghz, a higher TDP at 112W and supports its stock speeds of 2666Mhz of DDR4 RAM so comparing it to the 7700K won't be accurate.
    Because the 7700K is mostly made for gaming, it would be great if Intel just left the IGP out.

    The IGP is still there jus disabled. Thermally it does not make much difference when disabled like in our desktop systems.
