Answers :

The fan should have a red and black wire. You don't need the other one or two wires if there is (yellow/blue are for monitoring, if they are there).

The fan will take anywhere from 5V to 13V, so depending on how much noise you want you can change it.

As for the amperage, you want at least 1A. Most fans take 0.3A, but some powerful ones can take up to 0.6A. The quick easy route: Go with 12V and 1A., so 12W.

As for running them in parallel, sure you can. I've done it myself many times. Just match red with red and black with black, so that the endings are still just one black wire and one red wire. You can chain as many as you want, but add 1A for each fan.

The computer sounds like it's racing. It speeds up and slows down. It's not the normal sound, it's been doing this for about two weeks and I cleaned the dust out of the fans that I could get to.

If the PC is a few years old, the bearing on the fans might be failing, causing more noise. The speeding/slowing is because the temperature sensors on the motherboard, fan, or case are telling the fans what speed to go for more or less cooling. ... PC Desktops
