Yes I tried it, not with the stock fan, cos it wont go the other way so i got a CoolerMaster and put it the right way first blowing down on the CPU core, and the temps were 35-37 at idle, and 40-41 n full load. and i reversed the fan to push air away from the core, and the temps are a little higher, idle 38, and full load 41. remember i just changed the fan, the heatsink is still the stock AMD one.
I also wanted to know what is the sound and air spinning speed for the stock AMD Fan, cos the myine used to wrun at 4500RPM, and the cooler Master runs at 6000RPM
