This is going to sound odd, but I need a way of powering two 120mm exhaust fans in the top of my PC case. For some reason, these particular fans keep burning out the power connectors that I plug them into. The fans are not obstructed and spin freely. I don't think replacing them will necessarily fix the issue (though I plan to do that as well). I think it's just "drag" from trying to suck air out of a smallish mid-tower case. I need another way of powering these fans (at least until I can figure out why they they keep burning out my plugs). I considered the USB port, but they only output 5v and not enough amps (and last thing I want is to burn out a USB port.). Batteries may work, but they'd drain awfully fast. Any other ideas? Thx.
