Hi everyone. So as anyone with a Titanium PowerBook G4 knows, these puppies get really hot! The other day, being fed up with my 667 MHz PB deep-frying my lap, I headed over to CompUSA and bought a 1 GHz Titanium PowerBook with a dead logic board for a few hundred dollars. I took out the heat sinks and fans from the 1 GHz unit and transplanted them into my laptop. Had to solder on one fan, but the solder job went perfectly. Everything went back together fine and the machine booted up perfectly. A bit cooler than before. One problem though... The fan that my powerbook doesn't have, the one located right next to the cardbus slot, won't spin! I tested everything out and I'm thinking it's a software issue. So, the point of all this is to ask: Is there any option I have to enable to get power to this fan? A kernal extension I have to modify? If not, can I splice into the power being used for the other fan? Basically, is there anything that can be done to make this fan run.
And yes, the solder job is fine, everything checked out with a voltage meter and nothing was damaged. I'm an apple certified tech.
Thanks!
Oh... I have pictures if anyone would be interested.
It needs a PWM input in order to set it's duty cycle.
the DVI 'Books already have a connector for the second fan. If so, what's the soldering thing all about?
If not DVI, I congratulate you on combining a DVI heat sink with a gigE MLB. I didn't think they fit together. Can't help with the fan problem there though.

Pulse Width Modulation? I did a bit of googling around and haven't been able to turn up much on your tip. Would you mind elaborating a bit? Is it feasible to supply PWM input? Is there any way to get around this and have the secondary fan follow the cycle of the main fan?
It's a 667 MHz Titanium, with a DVI connector. For some reason my 'book has the solder points on the motherboard, but not a connector soldered onto it.
