Hello, about 2 days ago I noticed a very faint burning smell coming from my exhuast fan. I checked all tempatures in the computer and all are average. GPU 34c idle and CPU 30c idle, PSU/HDD/SSD all were all extremly cool, (Felt them while grounded) and determined it might be dust problem. I maintain my computer very well so there wasn't much dust. I stripped down the computer and dusted it and rebooted the computer and the smell is still there. Very faint, but I still wanna take proper percaution. Any things I should look for or test? Could it be one of the case fans burning out?
