a bottle of this will take any thermal compound off....

http://www.newegg.com/Product/Product.aspx?Item=N82E16835154006 don't worry about getting the cpu a little wet as long as you dry it all up... use a can of compressed air to check for wet spots after cleaning it off.

I've found acetone usefull for such things- just don't get it on any plastic.

I wouldn't advise that unless the CPU is mounted on the motherboard. Rapidly moving air of results in a static charge. Static discharge tends to kill electronics.

Hmm.. I'm not careful enough to recommend acetone to anyone.... but yes, I even find it easier to clean a CPU if it's still mounted in the motherboard. That way, something is holding it in place properly besides my fat fingers. :-P

zpm: I haven't used that stuff, but it looks quality. I bought a removal kit from FrozenCPU, but the effect is the same.

I just use plain old rubbing alcohol to get the old thermal paste off, works just as well.

Well, I did use the alcohol to totally remove and clean both the CPU top and the bottom of the heatsink. Then, went down to local parts store, and got a tube of the silver-based thermal gel. A smooth, thin coat was laid down and the heatsink installed. Now going through a few heat up / cool down cycles to make sure everything is OK before fully loading the cores again.

Have both RealTemp v. 3.0 and SpeedFan v. 4.38 laid on and operating in tandem to monitor temps. Will make some runs tonight, and see what develops. Thanks to everyone for their suggestions/comments/warnings ....

I've used this Arctic Silver ACN-60ML (2-PC-SET) Thermal material Remover & Surface Purifier for a couple years, seems to work quite well with Arctic Silver 5 (the only past I use), and has had 100's of + feedback on Neweggs site. Just another thought.

*edit: don't forget to lap your heatsink if you want to squeeze out the last couple C's of temp from your cooling setup*

The only problem with acetone is that it will leave a film. You will still need to use alcohol to remove the residue. And yes, no air spray unless the CPU is still mounted in the board, and the system is plugged in ( but off ) so you have proper grounding. I've seen more people kill their electronics, PCs and otherwise, using compressed air or vacuums, than you can shake a stick at! It's amazing how much static electricity air flow can produce, you definitely need grounding to drain it away...

If you're using nail polish remover, yes.
If you're using straight acetone, no.

To clean off thermal compound in the past I have just used an old rag, made out of old cotton undies. Yes, Clean ones....

The best is to use simple isopropyl alcohol and a lint free wiper.......

That is a good idea as well, but I'd imagine it might make my coffee taste funny. I generally stay away from paper products if I'm worried about lint or paper dust. We have these towels at work for cleaning up printer toner spills. They are really nice for it and reusable. I assume they are washable as well but in our situation we just toss one out once it stops picking stuff up. Which after 3 years I'm still using one of the same ones. It looks filthy but it cleans things up and holds onto it. I consider them a form of magic.

Don't have to worry about those temps here's my Q9300 under full load 24/7 with a better than stock cooler.

Try using plain old Vaseline (that's petroleum jelly for you non-Americans) for thermal compound - it never dries out, fills the air gaps perfectly, is cheap and is trivial to clean up. I use it on all my computers, many of which are on 24/7. But: I use AMD CPUs, which don't run as hot as Intel, so maybe that's why it works OK for me.

Go to the auto store and get some clear silicone grease.
They use it to facilitate thermal transfer from the ignition module to the heatsinks....
Works great for the same on a computer......
It's what keeps the Frozen Nehi frozen.........
It does migrate a little bit.....but does not harden or cause other problems.
Messy, but it can be cleaned up.
And I use MX=2 on the heatsink.

It's been a few years since that was the case.
Even Intel's Extreme Edition Core 2 based CPUs run cooler than AMDs. The days of the P4 are long gone.

I stand corrected...however, based on what I've read in these fora about Intel temps, the Barcelonas do seem to run cooler - I get < 50C on my CPUs running SETI 24/7. But they are running at stock speed, so maybe that's the diff.

My E6600 cores sit at around 50°-54°c running at stock speed (2.4GHz). But that's running an optimised application, and with ambient temperatures anywhere from 28° up to 35°c (or more on a really bad day).

I gave up temp monitoring a long time ago...there are soooooooo many issues with the temp monitoring prgrams that I don't know what to believe anyway.

I run 'em 'till they quit running.
And I have not burnt one up yet.
The mobo or psu seem to be the weak points.
If the temp gets too high, the rig shuts down. End of line.

So I just push the envelop until it collapses.
And then I know I have gone too far.

But no cpu calamity.

Ever.

So......push it. When is doesn't run anymore, you will know.
