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?
so, you are well within the limits of your CPU, and you can deff. go much higher.
Even for non-overclockers, i never recommend the stock fan/heatsink. They are not as reliable as the aftermarket products and don't do anywhere near as good of a job
You can run the fan at 100% if you don't mind the noise.
the tweaking you've done will have a minuscule effect on the lifespan of the product. you won't notice it
