I went ahead and had the local electronic repair shop throw in a new fan in my A2000 psu, as the old one was getting pretty loud and I'm not so good with a soldering gun. And instead of blowing air out, it now sucks air in, so I called and said I thought it was backwards and he said he did that on purpose because it's better to pull air in for cooling than blowing air out, and that it will increase the lifespan of the psu and the fan because you're not dragging hot air across it, and that all the modern psu's do that...
