My PC fan is making a random Whirring/buzzing sound (like a hairdryer) every 15 minutes while gaming

This issue happens in a few games such as Borderlands and Aliens CM (which are both gearbox games?) but it is really getting on my nerves. Plus it's scary because one of my graphics cards is burnt out and awaiting repair (since then I've added a fourth fan) but do you guys have any idea what could be causing it? The issue lasts about 15 seconds each and the noise spikes then gradually quiets down

  1. Is the fan dirty? If not then the fan is defective. Replace it. They do not last forever. My best guess is that the bearing is worn.

    I bought my rig parts in March of this year. Don't think it's the case. (No pun intended)
  3. Makes no difference the fan can still be bad. If the fan is clean and if there is nothing rubbing against the fan blades but the fan exhibits periodic noise; then it is defective. The reasons fans make any noise (other than normal air flow sound) is if they are very dirty, have some object that rubs against the spinning blades or are defective. One other possibility is the fan is not tightly secured to the case or whatever else it is mounted to. Is this a case or cpu cooler fan? Either way get a new on and replace it.

    No signifigant GPU or CPU temp spikes... Think I'm ok.
