    Nice work, 68c max is something really impressive, please give some light about the BIOS settings you are using in this test.

    Thanks for sharing. This is will save me a lot of money in the future.
    Here is the link?:
    https://www.caseking.de/en/der8auer-core-i7-8700k-5-2-ghz-ultra-edition-cpbu-162.html

    Need one for Kaby Lake now. If anyone spots one; then share it here please.

    I might stop the making of the .999 silver BitsPower IHS lid to save money. I want to move on to the P870KM1 heatsink, which I love to be in solid .999 silver. Also it be great if the heatsink be bareback, meaning no IHS on the CPU, just a straight heatsink clamp to the die. Does anyone know where to buy a P870KM1 CPU grid heatsink please?

    Well, in the link above; Der8auer are stating:

    "An additional reduction of 8 to 12 °C temperatures can be expected due to the exchange of the business standard Integrated Heatspreader (IHS) with a silver heatspreader. The der8auer Ultra Edition is the absolute apex in all things related to CPU modding and offers the very best overclocking performance."

    On my tests, I am only getting a 2c drop on the 7700K CPU! but mine is in .925 silver and not in .999 silver like theirs.

    As for the oxidizing; I have not opened up and checked my .925 Silver lid yet. I am going to wait another month at least. I will post photos here for future reference.

    EDIT: The down fall to their silver IHS lid, is the height. The P870 CPU heatsinks needs that extra 1mm of height to fill in the gap for a better contact. For a desktop though, I bet their ace :cool:

    As requested by some:
    I have finished the video of the same run as last test on Battlefield: Hardline using the .925 Silver lid, but with "Full" fans on Clevo dash and full fans on the x3 U3+ Vardar mod cooler. The last test was on "Automatic" fans through the Clevo dash and 40% 1100RPM x3 U3+ Vardar mod cooler.

    Last video (Auto Fans, 40% 1100RPM x3 Vardar cooler)
    2x 1080 GPU: 57c max
    CPU 7700K 4.5GHz: 68c max


    This Video (Full Fans, 100% 3000RPM x3 Vardar cooler)
    2x 1080 GPU: 49c max
    CPU 7700K 4.5Ghz: 62c max
