I have one, and it doesn't run hot in my experience, at least with my Cooler Master Hyper 212 Evo on it. I'm running at 29-30 deg. C right now web browsing. When I put a mild overclock on it (up to two cores 42x, four cores 39x), and do a video encode in HandBrake with all four cores pegged at 100% and all running at just over 3.9 GHz, the CPU temperature never rises above 62 deg. C.
