But the silicone grease in electronic stores work better.

Answer 2

I would never use anything as thermal grease that is not certified to be placed on the processor as you run the risk of killing the PC.

Answer 3

lol @ first answer

NO, you should buy thermal compound and use nothing else. You can also buy thermal pads, but thermal compound is better.

May I suggest Arctic Silver 5: http://www.arcticsilver.com/as5.htm

The reason is that you need a compound that can and is efficient at dissipating heat. No household items can replace thermal compound or pads. If your processor overheats, it will fry.
