Hey everyone, lately I've been trying to quiet down my fan, and I think I have one more trick up my sleeve before buying a new one. When I installed my motherboard, I set the input to 230V... because nothing would happen at 115V. And my fan was like screaming. It's been running fine at 230V, but I think its giving the fan too much power, but when I turn off my PC and switch the PSU to 115V, it wont start up?! Anyone know why I have hit this roadblock? Thanks in advance. P.S. I live in the USA.. the input should be 115V btw.
