uhh.......try scrapping it off with ur nail, ive always want to try this, but i dont think it's safe to do lol.
i got a good question, since im on tonight n im going to bed right now, is it a good idea to........i dont know........take off everything off a graphics card, remove the thermal paste on it already n replace it with Artic Silver 5? Reason i ask this is because if i ever plan on doing OCing again, i want to do it on the future HD 2900 XTX.
