as the topic says i got problem with my cpu temperature, as i run battlefield3 or some games with good graphic, it gets laggy and my cpu temp at the moment is 255 by the core temperature software(and some other programs such as amd overdrive).
with my stock fan on cpu it's no problem with the heat just the sound and loud noise for spining 6000rpm of the fan!!!! (that's the reason i got the new cooler Buffalo100)
some ppl suggest to lower the voltage of cpu, but i dont know how to do it and not sure if it's safe!
here's the pic for cpu temperature chart http://www.rodfile.com/n69ed13b3p7p
