Voltages off a 3 pin fan connector

[dave cummings]

Hello all!
I am playing around with designing a custom built cooloing solution for my pc, sad I know but i want to learn a bit more about electronics.

What i have is an abit kd7a mainboard (yes yes crap I know).

I have a few 3 pin connectors and i would like to power this system from the mainboard if possible, does anyone know what the voltages are without me having to physically check them?

or if anyone has done this before would you power it directly from the power supply or from the mainboard like i propose?

cheers guys and gals!

dave

They're 12 volts. Most boards can't supply a lot of current to them though, so be careful not to add too much load to them.
