PC fan on 30 volts

[BrianG]

Wiring it is really simple - especially if you stick to 12v (you can wire a 12v regulator to provide more voltage).

- Run a small 20GA wire from + of your main battery to pin 1 (left) of the regulator.
- Run a small 20GA wire from pin 3 of the regulator to the + lead of your fan.
- Run a small 20GA wire from - of your main battery to pin 2 (center) of the regulator.
- Run a small 20GA wire from from pin 2 (center) of the regulator to the - lead of your fan.

Put a heatsink on the IC and use a thermal insulator pad. IIRC, the tab on the IC is common to the output pin and if it touches any negative lead, it will damage the IC.

I'd stick to the 12v fans as they will move more air and are far easier to find. You can use a fan from a computer video card, chipset fan, CPU, etc and those all use 12v.
