Oh. I guess is going bad even tho I recently bought my pc since I recently cleaned my pc about 2 weeks ago.It sounds like a fan starting to go bad or just needs a good cleaning.
Alrighty. ThanksYou could also check to see if any of them are loose. Take the side off and start the machine up then just put your finger on the frame of each fan one at a time to see where the noise is. It's possible it could also be loose.
