cleaning CPU before applying Thermal Paste?

[peegee]

hi - I'm installing an Opteron 280 CPU with a Zalman Heatsink, and am ready to roll, but seem to recall something about cleaning the CPU surface before putting the paste on - but with what?
nail polish remover? lighter fuel?
or is it all just nonsense?

thanks all,
paul

Please search; this has been asked quite a few times recently.

High-purity isopropyl alcohol ("rubbing alcohol") will work, as will 100% acetone ("nail polish remover"). Do NOT use 'nail polish remover' that is not 100% acetone, as it will leave residue.

If it is a brand-new CPU/heatsink, this is unlikely to make much of a difference (though if you have been handling it, you should clean it, since oils from your skin can interfere with the TIM). You should always clean the CPU and heatsink surfaces if you have to remove the heatsink after applying thermal paste.

Is this a new Opteron or was it installed before? If it's new, then you don't need to clean it since it's already clean.

Anyways, I use Goo Gone and a tissue to wipe off the old thermal paste if I need to clean the CPU. It's quick and painless to do.

as high percent alcohol as you can get if its already been used.

thanks all for speedy answer. will go get rubbing alcohol and clean the (pre-owned) CPU's. the cooler itself is brand new and untouched by human hand.
or animal paw.

As Matthias99 said, Get high-purity isopropyl alcohol. Walgreens or CVS will likely have at least 91%. You should try asking the pharmacist if there is any 99% though -- it might not be on the shelf (I think since it's highly flammable).

And while you're there, try to pick up some lint-free cloths (like the ones used for cleaning eyeglasses). Or you can try coffee filters! The bottom line is that you don't want any lint/fibers remaining after you clean.
