trying to overclock my athlon II X4 630 with amd overdrive, at max cpu load for an hour the temp gets no higher than 49 C. It seems to be completley stable, is it okay with this max temp? Also is it okay that I am doing this with a stock heatsink fan? if anyone has overclocked this chip in a similar configuration let me know what your results were. stock clock was at 2.8 and I think i have successfully raised it to 3.0. Final question: is it okay to run fan 0 at 80% constantly with manual control?
