what the hell? i went to remove the IHS on my a64 3700+ and managed to. Guess what? Instead of getting lower temps they sky rocketed to around 60c and now i cant keep it at 2.6 ghz @ 1.52v anymore. I'm running @ stock or it gets too hot (im using a zalman 9500 cps) my advice is to ignore everyone here and never remove the IHS on your cpus. Nice, now my cpu runs hotter.
