If you've bought the Vantec Thermoflow, here's how to substitute the thermistor for a potentiometer, thus creating a fan controller.

Firstly, break off some of the plastic covering the fan PCB, above where the thermistor is attached. I haven't got any pics here, but it's a small green thing sticking out the side of the central part of the fan. It's hard to miss.

Just chop off its' legs. If you dont want to break the plastic fan covering, you may be able to solder the wires onto what remains of its legs, but this didn't work for me, so I soldered the wires onto the joints that it was attached to. They're a bit hard to see in this pic, but very easy to find - just look for the spots where the two ends of the thermistor are attached to the PCB.

Solder on the two wires like so, and attach the other ends to the potentiometer. You can then adjust the potentiometer to alter the fan speed.
