thermal paste

[blondeattk]

having some overheating problems with current pc, so might build one that bigger with better cooling.

Was looking at thermal paste on ebay, and there is quite a range to choose from.

Any tips on what not to go for? Does it matter if its silver white or made from yak excrament?

advice appreciated )

sadly all the local comp shops have gone bust in the recession, so no one local to ask.
