Just got a Zalman MFC2 controler. It comes with a PWM controler fan adaptor that, for the moment, I dont plan to use since I prefer to have the mobo controling the rpm of the cpu fan.

However I would love to use the MFC2 display to show up the current rpm of the cpu fan (4 pin fan on the artic freezer 7).

My plan is to wire to the MFC2 just the pins that bring the rpm info.

So, the questions are : anyone around with a similar experience? If not, can someone link me to a place with info about pwm fans or give me some info about it ?

Thx in advance,

System: 8400 on a Asus P5E / 8800 gts / cm690
