I recently built a new system and it's been running fine except for one problem which has been getting worse. Basically, the CPU fan keeps cutting out then coming back in at max speed to compensate for the heat build up. After about 10 mins the PC shuts down. It used to happen once every couple of weeks but now it's every day.
I'm using the Intel Quad Core Q6600's stock cooler (no gaming on this rig) and using Abit's FanEQ control on the Abit IP35 Pro mobo to adjust speed from 30% at 30C to 100% at 45C. When I disable the fan speed control (FanEQ) it doesn't seem to have this problem but it's not ideal because of the noise level. I intend getting a decent cooler for it but I'm not sure if this is a fan or motherboard problem.
Any ideas what this problem could be?
Thanks for your time,
