Help! PS2 fan!!!

Hey guys. Can anyone point out an alternative point on the PS2 motherboard / power board i can power the fan from? I just snapped off the connector, and somehow now even when i solder on the fan its not working. I have now got the fan on battery power ( :-o ) but want it back to normal.

Any idea's? I dont mind changing up to a 12V fan and running somewhere off the power board if thats easier.

Cheers

Oh, i forgot to add. My PS2 is a V4, UK model.

Cheers.
