The flattest CPU in the world, lapping done right [3950x]


I made this video to share the story of how and why I used a free abrasive process to create a CPU far flatter than ever done before.

Very interesting how 2 flat surfaces stick together like that. Making the need for thermal compound moot.

Interested in Part 2 of this to see thermals with and without thermal paste.

Yes, you still need TIM. You always need some kind of an interface between any surface, especially heat transfering one.

TIM at >4 W/mk is required to fill micro-crevices between two metals so air doesnt at 0.024 W/mk regardless of how flat one thinks the surfaces.
