I bought this when I built the system thinking I just might need it sooner or later. When I swapped out the OEM heatsink, I just clean the CPU with alcohol and a coffee filter. This time since it's a system tear down I got it out and gave it a try. You can get this from NewEgg for $6.00usd
Its smell makes me think it's a cirtus based cleaner. Matter of fact when I put the first drop on the heatsink, the scent was unmistakable. Orange oil.
Ok so this post is just the Reader's Digest version of getting the heatsink and CPU heat spreader cleaned up. We'll start with the heat sink.This is a nasty critter. Normally you would wipe off the excess paste but I wanted to see how well it really works so I left it in place.
I applied 3 drops and let it sit for 30 seconds then wiped it off with a coffee filter. The gal in the cafe thinks I'm nuts for asking for some filters. They work best for getting paste off and I didn't have any handy.
I did this twice to be sure it all came off. I then applied the polisher which is actually a solvent in its own right. It cuts the citric oil and what ever is left on the metal. And you get an all clean ready to remount contact plate.
TADA!!! Beats a dry coffee filter and alcohol by a counrty mile.
Next up is the CPU heat spreader. UGH! I wiped off the excess down to where I could read the branding on the spreader. 2 drops of bottle 1 and ran it around with a Q-tip. I did that twice. I did let it sit on the metal for 30 seconds each time. Here's before.
After the filter wipe down.
After 2 applications of cleaner.
And after 2 applications of polisher.
After the filter wipe down you don't see much differance in the other pictures. After applying the drops the liquid spreads out and you can see a black ring form as it eats up the oily residue. When you wipe it off the general apperance is like night and day. The lighting over my bench stinks so you can't really see the differances in each stage. It's one of those you just have to see it first hand.
Now to flush out the fins and get the sluge build up out where the brush can't reach.
