I want to turn the fan on when the room with my computer gets too hot; the fan (and the model that has a temperature controller) is PMW controlled, but I cant find something that would let me use the aquacomputer in its place to set the value for the fan speed.
If the fan only needs the PWM sginal it could work of course. In this case the 24V shouldn't be a problem as the aquaero will not deal with this voltage.
We have controlled many things with the aquaero. Nearly anything is possible
