Geez, 18c. Do you remember what the E6700 @ 3.2 ran at with the stock cooler? I just installed a ARCTIC COOLING Freezer 7 Pro Rev.2
on my E8400 @ 3.456GHz and it brought the idle temps from 45c to 41c and load (mirror's edge+wine) from 57c to 48c. Maybe Rev 2 isn't as good as the original. 4-9c is fine with me anyway..
