heatsink to cpu pressure

post #1 of 5
Thread Starter 
ok serious question time since this is something I've never really found an answer for what is the proper pressure between the heatsink base and the cpu something I'm curious about as I have to pull mine off and add the new fan and reseat it all.

Ive never really found a proper pressure amount listened anywhere so if someone could help I'd really appreciate it.

Normally you go until you cant turn it anymore without using extra force. Kind of like a soft tight fit i guess. Not entirely sure though, every heatsink i had in the past had springs on the screws to stop too much force being applied.

The HSF contact pressure is never listed, only the designers and engineers in the basement know what they are. Anyway, the mounting pressure is predetermined and if you mount it stock (with no modifications) it will provide the right amount of pressure. For push-pin type, just press down on each pin until you feel the contact click and lock. For screw type, just tighten each one slowly until the screw stops turning.

well what I'm using is the Xigmatek Aegir Mega killer. and I've basically applied my thermal paste as normal for me. Using a razor blade and filling in the gaps between the copper heat pipes and aluminum base. Then spreading as thin of a layer as possible over the entire base part that sits on the Chip. Then tightening it down with the included tool until I can't move it with a good amount of force.

Just Hope it's right.

Temps at idle show between 28-29c in a room thats about 24 to 26c ambient. motherboard reads 27c ambient. So I think its pretty close to right.
