Wish your computer was quieter? Was it quiet when you bought it?
Most PC fans are ball bearing type. They eventually wear down and then the fans starts to make noise. This noise can get very loud at times.
If your fan is making noise, that is better than it not making ANY noise. If it was loud yesterday and today it isn’t, dont think it magically fixed itself. It usually means the fan isnt spinning at all!
Big problem. That is the road to system overheating, and eventually a shut down.
Get your noisy fans fixed before they become silent fans.
