Swapped out the 3700+ being cooled by an Arctic Freezer 64 for a 3500+ @ 2500Mhz being cooled by a lapped to 600 grit Arctic Freezer 64 Pro and idle temps have dropped to 39 degrees. The TDP of the chips is 62W v 38W. This week I am going to have an OCing shootout between the two. Might throw my little 3000+ in there too.
