I've got a fan speed controller that handles only 3 pin connectors. I'd like to use it to control an Antec LED fan which has a 4 pin Molex for power (uses 2 wires) and a 3 pin connector containing just one wire (for speed sensing). Is there a way to make this work with the fan controller so I can adjust speed and view the RPM? Thanks.

you need to take out/cut off the wires from the 3 pin connector(not the rpm one) and connect them to the 2 matching wires on the 4pin. You can get adaptors though, but i dont know where from, mine came with my fans.
