its as the title says, curious as to if I can control me cpu fan and rear exaust fan with 1 fan-mate ?

edit : fan-mate 2 if it matters between 1 and 2.

I was doing that for a while so I know you can. I just put a splitter after the FM2 to the two fans like you. I used a splitter with one of the three leads missing an RPM monitor wire so that I could still read RPMs for one of the fans. The limitation should be the total power consumed by the two fans. Two slow speed fans should be well within the 6 W allowable (I got the number from Newegg).

well, I'm running a 92mm low rpm (1400rpm) nmb on the rear, and a tt slow rpm on the cpu (2000rpm) also a 92mm fan I guess they should be under 6w right ? what do low rpm 92mm fans run ? (I'm talking about watts lol)

Check on the fan label. V * A = W if given in amps.

I'm guessing about 2 watts max on startup (at 0-100 rpm) with the Fanmate turned up to maximum. At minimum, you can expect the power draw to be less than 1 watt for both fans combined. You could add more to that Fanmate and still be safe...as long as power draw is less or equal to .50 amp / 6 watts total.

so .5 amp is equal to 6w ? cool, then both of them together is like .2 probably...if that, since they are both low rpm fans.

edit : also, when I run it like that, do both fans get 12v at max and 5v at low ? or does having 2 fans mess with it and you actually get lower values?
