I bought a te 750W powersupply 1 month ago, from de very beginning the supply makes some tikking noise, coming from de fan in the supply. It looks like, the regulator for the fan-speed is giving pulses to the fan, and this is what I hear. Full speed , no noise , between 0 and full speed , it is making noise. I tought it would be acceptable, but it is becoming very annoying, as the rest of the desktop is very quiet. Is there something to do on it , or do I have to send it back to the supplier ?
