Can I use a 2-pin fan on a 3-pin connector?
Posted on 2004-10-17
I have an hp pavillion 724a with a faulty system cooling fan (ducted onto the cpu) which has 3-wires (pos, neg & feedback) and i only have one spare 90mm fan which is only 2 leads (pos & neg). Can i modify the 3-pin connector in some way to allow the feedback (yellow wire) to be bypassed?
My initial thought was to install the new fan, connecting it to a standard 12v PSU connector and simply disable the system cooling fan monitor in bios..... however, bios indicates only whether the fan is working and what it's speed is.
It does not allow me to disable it. :-(
I need to get this pc running as quickly as possible.
