The retail heatsink absolutely sucks. I have that CPU and the stock sink is VERY load. I purchased an aftermarket dual fan cooler and it is quite quiet. The cpu is a heat generator and my computer room is one room I do not have to heat in the winter! lol

Thats what i thought for a stock HSFThe stock heatsink is actually quite good imo. At stock frequencies, anyway.
Thuban temp sensors are incorrect. You should add between 10 & 15C to those temps.
Grab HWMonitor and see what the cpu socket temp is and go by that.
