I'm building the DIY projector, and it calls for a pc fan to keep it cool. I have the fan and a power supply, but when i hook them up the fan does nothing. I know for sure the fan works b/c I hooked it up to my PC and it came on. I used the standard 4-pin connector. I ordered the power supply on newegg and its brand new, so I'm hoping it's not the problem, but I dont know what would be the problem. Any help?

Is it an ATX power supply? You're supposed to have those connected to a motherboard to switch them on. The motherboard jumps the green wire to ground, which you could do manually if desired.

Yes it is an ATX. So what exactly would I have to do? Sorry I'm more of a software kind of guy haha. I'm guessing I would have to just strip the green wire from the 20 pin connection and run it to something metal?

Just shove a wire into the socket end of the green wire and shove the other end of the wire in the socket end of a black ground wire.

Like folken said, you just jump a piece of wire from the green wire's hole to any black wire's hole.

You should be aware that power supplies have a "minimum load" on all voltage rails and that running them with only one voltage in use could damage them over time. Then again, it might not.
