My (ASUS X401A) laptop's fan is making loud noises again. Usually blowing into the vent is enough, but this time neither blowing or compressed air is working. It is louder than ever, and the more windows I open the louder it gets. I tried changing the fan speed in the BIOS, but the option isnt anywhere to be found. Having to work with a laptop fan this noisy is hell, and I'm all out of ideas. Please help!
