    I think many of us can be interested and can pay for any alloys or metallic mixture allow us to enhance the heat problems on all DTR's even for the heatsinks as well, the cost is an important factor but it's not the most. If you succeed to give us a solution makes a real difference, I'll be your first buyer. Good luck.

    Thank you. I would just like to inform this forum that gold has a lower thermal conductivity than silver. Diamond and graphine have a lot more thermal conductivity than silver, but is more expensive. And it's hard for them two materials to conduct heat on all directions. It depends on how the atoms are placed in them materials. And when the atoms have been placed probably in line, heat can only travel in one direction. So silver is the best thermal and electric conductor ever. This includes best light reflector too.

    The .925 silver lid that I have is 92.5% silver and 7.5% copper. The .999 silver lid that I have in the making is 99.9% silver. I think this is the best metal for controlled thermal conductivity for now.

    I will stay in touch with this forum. good day.

    How about an 1 piece IHS / Heatsink ?
    The big problem as I see it is making the contact between the two.

    That's what I'm thinking, but my head is telling me that I need to narrow the the heatsink connection on where it connects to the naked (no lid) CPU die, due to the LGA socket clamp needed to be clamped down to hold the cpu in place. This way, it will be one single connection. I'm still doing my research on it. Just the lid is confusing enough because of the casting shrinkage. I have already lost to moulding setups on the .925 version. Hopfully this .999 will end all this lid hassle. And thats when I will be thinking on going to heatsinks. I will keep you informed pal. Thanks for your thought ;)

    You run into socket issues and good pin contact going direct die.

    Thank you Meaker. Do you think there is a way around this?

    Mill the IHS until it is level with the core and press down on it too to spread the pressure.

    Gameplay temps and results for the .925 silver IHS lid and 17w/mk thermal pads on both. "Auto" fans and U3+ (3×) vardar fan mod with all fans set to 40%. More quieter that way.
