Cisco WS-C3750G-24TS-S1U fan wiring

Hi,

I was wondering if anyone could help me find out what each of the wires connecting the fan to the motherboard of the switch are for? With there being more than 2 I am assuming that there is more than just a positive and negative for power?

Thanks

Thanks, so it could be something like:

Red - positive 

Black - negative 

Blue - fan speed control 

Yellow - ground

Or blue and yellow the other way round?
