stinius,
I have a 4-wire processor fan working nicely and a 3-pin system fan connector, however, I rather need a small 2 terminal fan for the video card. Interconnecting the speed sensor outputs did not help. A hardware solution would be preferable.

Hi

As I told you here you will need to make a circuit that “simulates” a fan, on the control pin.

It’s as simple as a 555 with some extra components. I can email you the circuit if you drop me an email.
You can also try it by putting a square (digital) signal on the control pin, in the 35Hz to 150Hz range.

Cheers
Stinius
