    The full copper IHS is a hoax, it does nothing exept milk those that want the "finest" for their PC (as the original one have copper inside too and less heat resistant outside).
    The only thing that do something is the solder, and if you polish the original IHS too you will get the same or better result... For less money.

    I wouldn't mind paying Intel an extra £150 to have such a IHS on my 12900k.

    With thermodynamics the devil is in the details. I agree with the copper not making any noticable difference but if they can achieve better tolerances between the chip and the IHS (meaning less TIM required), a thinner IHS overall (less thermal resistance), and better surface finishes between both the chip and IHS and the IHS and cooler (less thermal resistance again). Then it will perform better than stock.

    the inner machining looks like an aliexpress thing, contact surface better be mirror smooth for me the be interested

    Uh... isn't the original IHS just nickel-plated copper? I'm sure 99% of the difference is the liquid metal compound.

    In other words, I can buy this kit that comes with everything already pre-packaged and done, or I can do it myself for a bit cheaper. Largely the same as a lot of products out there :p

    Just buy an AMD CPU instead - it won't require a nuclear plant to power it, nor will it melt when run on a stock cooler...

    I had a different experience for the short time i owned a 5800X, that thing could heat my house during the winter.

    You aren't getting the same result from a polish, 80% of the gains are from the liquid metal instead of solder.

    Yes difference being the new ihs is perfectly flat instead of concave/convex plus liquid metal.

    Probably because copper is more expensive

    With stock coolers the higher core/thread count AMD CPUs still run very hot unless you're in like a super cold room or something. Upgrading to a 240mm liquid cooler did somewhat improve temps for my 3900X, but that thing can get very hot under sustained all core loads (~90 degrees C).

    For users with the best cases, the best fans, and the best CPU coolers and paste money can buy you can reduce temps quite noticeably, but AMD CPUs definitely run hot as you go up the stack to the ones with more cores and threads. From what I've read the temps are still being pushed hard on Zen 3.

    This represents my experience with the 3900X too. When I moved and was able to bring down ambient temperatures in the room I game in, this had a noticeable effect on CPU temps in my case interestingly.

    yes but in this case it is just "cheaper", not "a bit cheaper" :) (even more if you do it with no box / no fan version

    The IHS on all modern CPU's is solid copper. Copper though is pretty bad with reacting to things in the air like oxygen so that's the only reason it's coated in nickel.

    I actually don't believe those numbers, i have lapped and removed heat sinks before and the best results i had was only ever about 4-5C and that was using the best available paste. I call BS on 15C. Unless they had a dodgy IHS to begin with.

    full copper vs original copper nickel polish give almost the same result with IHS and, as you said, it is the paste or liquid metal or solder that give most of the gain.

    it is but it give nearly no gain over the normal IHS
