I'm waiting to grow some balls before I do it. $350 is a bit more than I usually gamble on something that would be cool, but that I don't really need since I'm already getting really good temps with my setup. 60C or less in Heaven and 65C or less in 3DMark11. 80C or less during a stress test in the Intel Extreme Tuning utility.The temps are only high when overvolting so no. At least it doesn't get as hot as a bulldozer cpu when overclocking.
I'm sure that they lost some sales over that decision though. Even still, I'm tempted to pick up a 3570k just to pop the IHS and see what I can do with it.
This is all for 4.6GHz @ 1.345v. I mean, 10C less would be nice, but it won't change anything in reality.
