The fan located next to the speaker in my G5 has gotten realy loud. It is 80 x 80 x 15 blows towards the pci slots and connects to the motherboard with a 4 pin connector. All of the fans Ive seen have 2 or 3 pins/reb-black/red-yellow-black.

The G5s fan wires are all black. Does any one know what each wire is, when plugged into motherboard from left to right?

If i just unpluged this fan and installed new fans to the molex power supplies connectors will i have any problems beacuase this fan is unplugged?

Is it possible to connect a 2 pin or 3 pin fan to the same motherboard connector as this fan plugs into ? Will this cause any errors or make hardware test report errors ?


Thanks

Don't have those pinouts I'm afraid, but I would hazard that running an alternative fan from a molex or elsewhere will cause the unit to fail hardware tests. I doubt it would have much more effect than that, but its possible that the other fans might speed up to compensate for the percveived lack.

Have you tried cleaning and oiling it?

Ive cleaned it, it is a bit quieter, but still noisy. I havnt tried to get the motor yet, it seems almost molded to it. I ordered a replacement fan but its gonna take while to arrive.  I have several artic fans now the same size but only 2 or 3 pin connectors on them, i was hoping i could use one of them but cant figure out thee 4 wires from the g5 fan.
