Hello all,

This is a neat little trick I just discovered when I got too much conductive heat sink compound on my CPU. It's not for the feint of heart, but it will work.

1) Screw up and get compound in the contacts under a cpu (in the junction between the CPU and holder in P4 chips)
2) Curse somewhat loudly.
3) Go to Pep boys and purchase some brake fluid
4) in a junk glass or non corrosive cup, pour the brake fluid in.
5) dump CPU into cup as well. it's getting a bath.
6) with a fine hair paint brush (we all build gundam and plane models right???) scrub the area with the thermal grease. It will come off
7) Take it out with tweezers or something of the like (remember that brake fluid is toxic folks)
8) dry with towels.
9) Insert into computer. It is now nice and clean.
10) Take the fluid to pep boys. they are required by law to recycle it, which is 100X better than dumping it down the drain and drinking it in your water in....3 months or so.

This works because most CPU packages are made of gold/metal and plastic resin/electronics board. Brake fluid eats paint (if you get it on your car). Thermal compound is based on a base similar to paint. Note that your brake piping is made of metal and your brake fluid came in a plastic container. This works to clean pewter models too.

Personally I'd probably just use a razorblade to even the compound out.
But your solution is much more hardcore :D (I'll probably test this technique sometime)

I just leave it there, it's non-conductive after all, so what damage can it do?

Aren't there some pastes which are conductive? e.g. ArcticSilver?

Nope; I use arctic silver, I guess I would've noticed by now...

From the website:
Code:
Not Electrically Conductive:
Arctic Silver 5 was formulated to conduct heat, not electricity.
(While much safer than electrically conductive silver and copper greases, Arctic Silver 5 should be kept away from electrical traces, pins, and leads. While it is not electrically conductive, the compound is very slightly capacitive and could potentially cause problems if it bridges two close-proximity electrical paths.)

well much to my bemusement, mine was conductive (hence this guide), and my motherboard was definaely not amused about it. After a good scrubbing in brake fluid, it works well...

also smells like the new car smell to....

:-D

just be very, veeeeery careful doing that. you scratch the top of the proc, you'll be sending it back to Newegg.com marked as "defective" :?

Hadn't thought about that actually :)
