Could a cpu fan make a buzzing sound ?

post #1 of 6
Thread Starter 
Check my rig details below, I bought a new fan/heat sink for my CPU like maybe 2 months ago. This sound I'm not sure where it's coming from. It's either the CPU fan or my HDD is going bad. It''s not my video card cause it's fan less. The fan is the only thing I've replaced in a while nothing else has changed, the PC been real quiet for a long time since built all new in 2011. I changed the fan everything is quiet for like two months and now theirs a low level buzzing/humming sound that is intermittently happening every couple of seconds. The sound can last 1 or 2 or 3 seconds long in any order. Now that I think about it there is a fan on my psu. I doubt it's the psu though. My pc is not OC'ed either right now. thanks

Sure it can be the CPU fan. Their rpm is usually heat controlled so its speed will vary. Its possible that there is a problem with the fans bearing causing it to buzz at higher rpm or there could be a dust ball rubbing against it.

You could disable the fan through the bios (or just unplug the fan) and see if the noise goes away. Don't put much load on the machine like that though as the CPU can overheat quite easily without active cooling.

Also check you've got everything screwed in/down till tight. Any little gaps can result in rattling or vibration noises. Check the hard drive is secured or try a suspension method to eliminate vibrations all together. Does the CPU heatsink have some rubber padding between it and the fan? If not you should put some in. All high end fans like Noctua and Phanteks have this to reduce vibration noises.
