it's only the CPU that's overheating, and I tried the boxfan, it lowered my CPU temperature by 30C. The thermal paste was already applied to the cooler when I got it. Is 3,516 RPM reasonable for a CPU fan?

The rpm is reasonable when the CPU is 100+°C, but temperature in that range is not in the first place.


Are the pins fully secured? Is there anything that could obstruct the contact between the heat sink and the CPU? Another possibility is that the heat problem comes from the chipset not the CPU. Try running a CPU stress program like Prime95 that stress the CPU alone. What's the temperature of the CPU and the North Bridge in this case.


It's a clear indication that you case is a problem. After you have everything sorted out and put back the 4850, one case fan is definitely not good enough. At the very least you want one that blows air in at the front or the side and one that blow air out at the back.

Everything is secure. I have an extra case that I can use, and I'm going to be trading a monitor for a CPU cooler and some other stuff.

OK. I have the new Cooler installed, and it runs at ~60-70C without the boxfan on it now. I'll move to a bigger case tomorrow.

Cool.
btw what is your CPU? I'd want to know which brand has such poor stock cooler.

It's an amd phenom II, x3. I think the problem is that tri-cores are really defective quad cores, and therefore it generates excess heat.
