Is there ANY way to control your PSU fan? Modding? Fan controllers? Anything. I've been waking up to the piercing sound of my PSU. I've manually stopped each fan in my computer and it makes no difference in the amount of sound it makes. I just need some way to make the PSU fan more silent. Model is Thermaltake Toughpower 750W. It falsely advertised 14CM silent fan. My case wasn't made to stifle sound or silence. BUT I know for a fact all the sound is coming from my PSU.
