Hi all...just ordered a new fan/heatsink to replace my stock Intel unit. It
is a Zalman CNPS7000A-AlCu btw. The only concern I have is removing the cpu
from the pad on the stock unit. I thought I read here or in another forum
that a certain type of rubbing alcohol is best to use to clean off the cpu.
Can anyone confirm or offer some suggestions?

Thanks..

i have used alcohol to do so...
it worked and caused no problems...however there may be other solvents
that are more effective...
i simply used alcohol because i had it on hand
plus it does not have any horribly toxic fumes

Turn system on.Run a good heavy Graphics game intro for ten mins or
more.This will put the system,"Under Load".This will soften the pad
but heating the CPU up just like running a car a few mins before
changing the oil.Use a twisting motion to get the HS off,don't try and
pull it off.
HTH :)

thanks all...If there is some of the pad left on the cpu rubbing alcohol
will be sufficient?

Thanks again..

Sure but sometimes you have to do some scraping. Actually if you are
diligent itll always come off with just lots of virgorous rubbing and
alcohol.

This is heresy but Ive actually used the PAD the last two times and
was surprised that it worked fine.

I also used to take it off and use Arctic Silver and the website
reviews all seem to suggest there is a few degrees improvement when
you move up from PAD to generic goo to arctic silver and other top
thermal grease brands though some have claimed an even bigger
improvement so always used Arctic Silver and I thought I got a fairly
large improvement when I tried the pad way back then vs arctic silver.

However recently Im impressed by the stock heatsink fan and even the
pad. Like I said Ive been buying the retail versions of the AMDs the
two times and use it stock and it works great. My 2500 barton OCed to
3200 stays in the range it always has with the stock fan and thermal
pad . The 2000 XP i bought for someone else two weeks ago works great
with stock pad and heatsink. Im also impressed at how quiet the stock
unit is and its effective at cooling to boot. The fan seems like its a
relatively low rpm unit. Its extremely quiet though there is some
noise thats noticeable , compared to my volcano and other fans Ive
been using on about 5 other systems . Those sound like screamers vs
the AMDs.

With the pad Im getting around 109 F -125 F on the barton and around
103 F - 114 F on the 2000 XP.

I havent measured these systems stressed for long periods at max load
so that might change the story a bit and tilt it in arctic silvers
favor or maybe not - I dont know.

If alcohol is all you have then try it, but generally the easiest way is
to use a petroleum-based solvent such as "Goo-Gone", or even WD-40. To
reduce the effort you can saturate a napkin and place it on the compound,
sealing it in a ziplock baggie for a little while... usually that's not
necessary but if you're not in a hurry it is the easiest way. The two
solvents I mentioned are not harmful to the CPU, though you might want to
avoid something like acetone.
