The power supply fan is not controllable from the motherboard or any software program, it is controlled by temp sensors in the power supply.

Dust can build up on the fan blades and in the heat sink fins which blocks air flow across them and in turn the fan speed increases to lower the temps, a handkerchief is not the way to clean heat sink fins, you can knock it loose or damage it.

Being that new I think maybe you should have it looked at under your warranty.
