My side fans are getting extremely loud and its very annoying. In the morning when i boot up its incredibly loud the vibration on the side is crazy...i put on fan silences basically a piece of plastic aroudn the frame of the fan. Its very annoying, i have to lightly hit the side of my computer case to stop it. This sound like i need new fans, they are about 2 years old and i cant stand the vibration, sometimes it turns on randomly...
