I've got my 600 boosted to 950 VCore at 1.7 and it's running rock solid. I left the case open and I've got a small desktop fan pushing air directly onto the CPU. Under load, it sits at 44°C with that setup. Without the fan on, it rises to around 50. I'll be upgrading the HSF in the near future. Just wanted to ask what kind of temps everyone else is running so I don't fry this bad boy.
