FX4100 Stock CPU Fan Tags: CPUs Desktops Monitors Last response: December 14, 2012 12:23 AM in CPUs Share mrfreez319 December 13, 2012 9:38:30 PM I recently put together a new desktop, and the CPU fan has been running about 1,800rpm at idle. Is this normal? It sounds louder than I would expect. I have used HW Monitor to monitor the CPU, and it is running at about 30c at idle. I have changed to PWM mode in the CPU Smart Fan Mode in BIOS. Here are my specs: GA-790A-DS3 motherboard FX4100 CPU with stock CPU cooler/fan Any help would be much appreciated!
