I doubt that your CPU temp is that low, even at 2.01GHz (unless AMD's Cool 'n Quiet is enabled, but even then its unlikely). That estimate is probably a little low. I doubt that smartfan is actually shutting your CPU fan off for 3 seconds at a time. That's probably not the source of the problem. I would still test the fan and if it does turn out to be defective, I wouldn't worry about having smartfan turned on... I have mine on and it keeps my PC running completely silent all the time. By the way, why do you need a 600 watt PSU for a 9800PRO and an A64 300?
I know that its that low cause I have a diagnostics program, called Everest, and it clearly states that it is at 28oC. Plus when I start comp, I enter bios and it says the cpu temp is 28oC. :D I know it was smart fan cause I enabled it then it had the problem so I disabled it and it is not been happening anymore.
To answer you'r question, Because im getting a 3400+ and a X800 pro soon, And just incase I wanna upgrade again I won't need another psu.
Fair enough. Just because Everest and your BIOS reports that your temps are 28C doesnt mean their right. I could be mistaken, but I believe that the BIOS and Everest cant take advantage of the thermal diode in the CPU core, so they have them underneath the CPU socket... the temps come a little low (since its underneath the CPU) so it adds on a few degrees to make up for it. Its highly likely that your temps are higher than 28C, and your BIOS just isnt compensating for it enough. Mine reports that my idle temps are about 23C (room temperature) and my load temps are aboud 30C (which is about where my idle temps should be, with the Cool 'n Quiet enabled), which isnt even close to right.
