Thermal Paste and IHS question

post #1 of 11
Thread Starter 
I thought you were supposed to spread a thin layer of thermal paste over the CPU and put the heat sink on but I have hear people say that you should put a small pea size dot in the middle of the CPU and just squish it with the heat sink. Which one is correct? Another question is how better cooling performance do you get from removing the integrated heat sink rather than leaving it on?

Either way works really. I personally spread it out with a piece of glass because it's always worked better for me. As for removing the heatspreader, I've heard the difference can be 10C, but I've also heard it can be 2C, but if you ask me, unless you're really serious, it's not worth voiding your warranty and potentially destroying your processor over.

Can someone who has removed their IHS tell me how much of a difference it made. I don't think im gonna try to remove it tho..... Also does anyone else and an opinion on how to apply thermal paste?

i always spread it out with a razor to get a nice very even/thin layer. but i plan on lapping my hs/ihs to help with making more contact.

I don't think I would put a Pea sized blob on it. that's kind of large. I remover my IHS It made about a 8 degree difference on load. Very dangerous operation though. I know people that weren't successful.

sounds like using a razor blade to spread it out makes more sense

I only dropped three degreese with my ihsless 3700. For tp, I put a rice grain sized dot on the ihs and spread it out over the entire surface with a guitar pick. Then i put another small rice grain size dot on the ihs and squish my water block down. It is the best of both worlds, but it takes practice to keep from putting too much paste on.

well the whole point of thremal paste is to even out the surfaces of the hs/ihs and bridge gaps left by imperfections on the faces of the hs/ihs. so a thin layer is all that is needed. lapping helps i hear thats my next big project.

You probably only lost 3 degrees because your on water. Meaning - The water already keeps it pretty low, ambient cant be far away.

yea air cools less you might not loose any heat with no ihs.
