be careful!
i have no clue how i've never had this problem... ive sanded the top of the IHS down to the copper + mirror finished it, still no problems... lol
you're supposed to use a type of rubber like neoprene to protect the pins, if the pins are slightly bent it doesn't hurt to touch them if that's what you're asking. just make sure there's no lint or rubbing alcohol left in there...
and ESPECIALLY do not spit on it! i know people who've blown on it... particles of spit must have fried their chip or something lol..
btw in your sig it says your ram is running 2T... 4sticks of 512mb?
2T can cut down performance ALOT btw. like 25% in some apps... of course near 0% in others lol.
