    Thank you. It's doesn't have the best enhanced edited videos but i thought its the best place to share some live results. Hopfully, some live results on the .999 silver IHS

    fun fact: caseking here in germany started to offer advanced, pro and ultra versions of cherry picked coffee lake cpus. 8700K goes up to 5.2 ghz with the ultra version sporting....*drumroll*... a silver ihs!

    reminded me of this thread ;)

    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?

    how is the silver IHS vs the old IHS? also does silver last and not oxidize like copper?

    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

    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.
