First you never mentioned what kind of CPU you have I'm going to assume P4, otherwise if ur overclocking ur AMD to that and complaining about that temp I'd slap you so hard you wouldnt know what hit you. P4's put out a ton of heat, there's nothing wrong with that temp, as long as it isnt hitting above 60C your just fine, the only easy fix is a bigger heatsink and fan, because simply you need to push heat away faster, otherwise check your case airflow if it slowly rises over time.
