Solder/plug fans into 9800GT contacts/connector

post #1 of 2
Thread Starter 
I'm looking to solder my VGA dual orb HSF to the PCB or plug them in to control the fan speed via the BIOS. GPU-Z shows that the BIOS does respond with fan speed control to temperature changes. If push comes to shove, I have a fan controller, but I'd like it to be automatic.

I'm wondering if just the two wires will be sufficient and PWM is managed by the BIOS or if I need to have a special 4 pin fan...

Obviously, those other pins relay information like voltage and RPM, but strictly for PWM, can I get away with just the two pins?
