If you need to get an additional fan running of your MOBO's PWM CPU Fan header, this will work, and provide monitoring of the second fan:
If you need more than one extra, you can simply 'daisy-chain' them:
PWM JEDEC spec says MOBO PWM headers 'should' supply 1.5A steady-state, and tolerate a 2.2A start-up surge. Most of the fans I've checked seem to run around .11 to .16 A, so several should be OK. Your mileage may vary. Good luck trying to find your MOBO's spec for this!
