This controller unit from Koolance allows speed adjustments of a pump or fan.

Many controllers are available for individual fans, but when trying to adjust the speed of a pump things get much more difficult. With this unit this is no problem: it can handle up to 3A which is plenty for most pumps on the water cooling market. The controller draws power directly from the PC's PSU via a 4-Pin Molex plug. A 3-Pin connector on the controller and the included adaptor allow pumps with a 4-Pin Molex connector as well as fans with a 3-Pin connector to be connected. Voltage and hence speed adjustments are made via the turning knob in the front connected to a potentiometer. For mounting self-adhesive Velcro strips as well as mounting screws are included.
