Do I need a new computer power supply, or can I fix this one?

I have a 650W power supply in my computer that I installed myself back when I asked this question (scroll through the answers on that for most system specs)
. This morning, the fan on the power supply started making noise. Do I need to replace the supply entirely, or is this something I can fix on my own?

Since I didn't list it previously, I have a 650W Cooler Master power supply. This morning, my computer started making what was obviously a fan noise, like sticking a baseball card in your bike wheel spokes kind of thing. Turning my computer on its side makes the noise almost completely go away. I took apart the computer and gave everything inside a good blow with compressed air, but the noise persists. I've DEFINITELY narrowed it down to the power supply - I've removed it and turned the computer on, which starts the fan; the noise occurs whenever the power supply's orientation is returned to what would be "upright" within the computer. There don't look to be any obstructions entering the fan path from within or without the power supply (since I've removed it from the casing, but still left the cables attached, and it still makes the noise, it's quite obviously something within the supply). It seems the fan blade itself is just riding lower than it used to, so the center is now resting on the grille at the bottom of the supply housing, so the blades hit the grille when turned upright. Is there a way to keep the fan riding high instead of dropping down again? There are high voltage warnings all over the exterior of the power supply, and it looks like I'd have to remove the whole cover to get to the fan, so is this something I can fix myself? The thing only cost about $80 - should I just get a new one?
