cpu and thermal paste

May 27, 2010 at 13:36:46
Specs: Windows 7, 2gb ddr
The duo core cpu i purchased came with a heatsink adn fan, there was some gray paste on the bottom of the heatsink so I did not add aditional paste to the cpu. I removed the heatsink several times from my mobo and the paste was dry. Should I go ahead remove this paste and add new fresh paste?

Yes, you should renew the thermal paste every time you remove the heat sink as a matter of routine. Before you add the new paste you should ensure you first remove all trace of the old paste.

Once a heatsink is installed, then removed, the old thermal material should be completely removed from the bottom of the heatsink & top of the CPU, then replaced with a fresh layer of paste. Why did you have to remove the heatsink several times?

Here are the instructions for applying paste. Follow them exactly, regardless of which brand of paste you use:

oh! i was building my first pc and the first mobo didn't work so i had to get another one and switch the cpu and heat sink from non working mobo.
Thanks for the info! I should go ahead and replace thermal paste before cpu burns out or something :/

I can't recommend any paste that is superior, But I can say, once you figure out how much to use, I would suggest cutting it in half. 'Too much' is the main problem encountered.

The three most important things in computing:
1. Backups, 2. Backups and 3. Backups.

The instructions jam linked to in #2 tell you how much to use. He and I both use the heatsink compound from Radio Shack for 3 bucks a tube. I bought two tubes several years ago when it was $1.99 and still have enough to last for years.

I've tested about a dozen different brands over the years and never found a difference I could measure close enough to call one a winner over another.

Only time I ever use a pad is when it comes installed on a new heatsink. I'd go for the grease.

You're putting way too much thought into this.

RadioShack Heat Sink Grease - $3

No. Most machines will go thru their normal lifetime with the original application.

Reasons to reapply are when removing/installing the heatsink, if working on an overheating problem, or if the pc is older than you are.

Just follow the instructions jam provided and try to put the rest of the tube somewhere you can find it later on.
