So i recently built my first computer and it works great but today i turned on the fan controller in my bios which makes the system alot quieter but now i have noticed a weird humming or chirping from my cpu. I also have noticed that it only occurs when the cpu is under very little or no stress. I tried looking through other forums and have not seen anyone with a similar issue. The humming does go away after i use a stress program (prime95) and when i have a game open.
More about6300 humming
That sounds like Coil whine from the Motherboard, its not the CPU, CPU's don't make any noise, there is nothing in them to generate noise....
