Thermal grease

post #1 of 14
Thread Starter 
I've been experimenting all day with how much grease i could or should put on my cooler.

Just the tiny drop smaller than a rice grain didn't work for me, my guess is it's cuz its an open die (That's what they call it right)

I now put on like two rice grains and my temp drop's 6 degrees Celsius.

Can anyone explain that?

Depens, do you spread it or just drop the heatsink on top of it ?

On open dies i would spread it, a tiny drop, spread evenly with an x-acto knife or a plastic card and you're good to go.

The BB or Rice Grain Method only applies to processors with a IHS.... i.e. Athlon 64, X2, or Core 2 Duo. The AMD XP do not have one and should NOT use that method. Instead, use

See what I don't get is that the arctic silver site says NOT to use the BB/rice grain for Core 2 Duo.

Honestly there seems to be a lot of different opinions on what works.

Personally I would go with what the manufacturer of the compound says to use for your specific chip. But this place is all about going OUTSIDE of manufacturers specs...so...hey..

For bare die CPU's I like to pute a tiny drop on the die (1/4 of a grain of rice), and put my finger inside a sandwich bag and spread it over the die with my finger inside the bag. The excess stick to the bag, and you get a nice even smooth coathing accross the die. Once your finished, turn the bag inside out and bin it. No mess, no fuss.

Doing that also to the heatsink will fill in any little holes creating a better contact. Just be sure to wipe off the excess. The area where you did that will be a little discolored, but do not try to wipe all of it off because then you're just defeating the purpose of what I formally said.

I've used the sandwich bag and couldn't ask for better temps

Too much is better than none! But the thinest layer possible is better than both (as long as your cpu and heatsink are flat).
