Hey,

I'm thinking of getting a new cooler for my CPU, but I already mounted the stock one on it. I don't want to damage my CPU when cleaning off the old paste.

Is it best to hold it gently by the edge and wipe in one direction with a lint-free cloth (or coffee filter) saturated with 70% + alcohol?

I haven't done this since 2007 and I used arctic cooling 1 and 2 solution which I don't want to use since it seems kind of old.

I am worried about damaging the gold connectors on the bottom so I was thinking I should hold it rather than have it on a anti static bag while wiping. Also I should probably wipe gently so that I don't damage what's under the metal cap?

Best solution

Seriously I have bought used CPUs guys have had laying around in their desk drawer

to be careful lay on anti static bag on top of cardboard on your desk

CPUs are tougher than you think
Just wipe off with regular hand pressure
It is easier if it just came out of computer then if it has cooled off for awhile
Look for %90 Isopropyl alcohol in pharmacy
Though %70 is fine if you cant find %90
Avoid rubbing alcohol since it has frangrances and menthol in it
I like coffee filters mainly because they are only about a $1 USD
for a large amount of them

these are about the best directions you will find on web
for applying paste by Arctic Silver
Even if you are not using their paste the directions are the best

just select intel or amd and then the cpu series

^+1 pretty well described.
Run your rig for a bit until the cpu is hot.
Makes removal of heatsink and paste easier.
I use 99% isoprophyl alcohol which is easy to find where i live.
Remove heatsink no reason to remove cpu from socket.
I just use a high quality paper towel like Bounty.
When it looks clean it's not.
You can still go at it and the filter/paper towel will still pick up residue.
Once it's clean reapply paste and heatsink.

Davcon and king smp,
Is it OK to use cotton swabs instead of a lint free cloth or paper towel?

Cotton swabs break up and leave debris strands.
Q-tips do the same but not as bad.
I've used a 100% cotton rag before = old undershirt for example.

I am not gonna be using cotton swabs then. Do you work using latex gloves or you have hands like a surgeon that don't need any assistance? :D

So do I need to wear latex gloves then guys?

Also does the pea method work for application of the Xigmatex Gaia heatsink?

FWIW, 98% Available at Pharmacies.
Coffee filters are lint free if slow on absorbtion.
You have paste, put a spot on metal, spoon will do, try out the Artic Cooling 1 and 2 on this. You can bake it first if you like 200 degrees F, lol.
My Experience is the A C product works much easiler.

there was a link in one of the other thermal paste posts that was posted yesterday that was great
here it is
http://benchmarkreviews.com/index.php?option=com_conten...
thanks to JM0090 for posting link

great article
worth reading the whole thing
also is link to 80 different pastes that were tested
Arctic Silver 5 came out with a surprising A+ top rating in test
it is a little older test but it shows that AS5 is still ok
By the way at Staples USA they have Antec Formula 5 Silver paste
that is the same compound as AS5
