TIA:

Have you felt the heatsink?  Is it hot to the touch?

If so, it could be that your cpu fan is not providing proper cooling!

I would replace the cpu fan with a small case fan that could attach to atleast 2 edges on the heat sink. You will need long screws simiklar to drywall screws.

The case fan will get power directly from the power supply and will not slow down or run fast as determined by MB sensors.  It will however run at constant speed providing great cooling effect!

Also a case fan placed near the CPU on the case itself may help also.
