Applying Liquid metal on the CPU

[batoot40mj]

So since people mostly use liquid metal thermal paste under the IHS, I was wondering is it possible to use it on top instead of the regular thermal paste? if so is it worth it?

Yes, it's possible although pretty difficult to apply properly. Also have to take care which LM and type of metals used on THS and cooler, some LMs and those metals don't go nice with each other making it more trouble than it's worth for few degrees gain. It's also dangerous as it's highly electrically conductive.

Lm are gallium based, which kills aluminium, basically it will bind with aluminium atoms to form some kind of amalgams and thus destroying the structure of aluminium heat sink, most of your cpu heat sinks, specially stock heat sinks are from aluminium, you should be okay with pure copper or nickel plated copper.

Also the reason they put it under IHS is that intel TIM has a much lower thermal conductivity, you can have a very good cooler , but if the heat can not be gtransfered onto the heat sink, it’s no uses. by replacing you weakest link, you get much better thermal results.

Heya Batoot

Short Version:
Possible YES --> But Take care!
Dont Spill any somewhere else, dont use much or it will run out of the sides and MAYBE short something.
AND DONT USE IT WITH AN ALUMINIUM COOLER! The Cooler is going to get destroyed! Copper is Ok.

It maybe will be some °C cooler but it will not be as good as if you delid the cpu and put under the IHS.
