![]() Powered by the PC power supply’s 12V line, the controller circuit itself draws a bit of juice, which results in at least a 0.5V loss - not at all significant in practice. It is almost never a full 12V, because most variable voltage controllers have some insertion loss. While some controllers provide selectable settings between 2 or more voltages, others provide a continuous range from as low as 0V all the way to almost 12V. PC fan controllers are not quite as ubiquitous as this kind of fan control… yet. For the silent PC enthusiast, a multi-channel fan controller is a neat, convenient way to tweak the speed of several fans for minimum noise or to push the fan speeds up as needed for special applications, hot weather, or what have you. It usually consists of controls and a printed circuit board mounted on a front panel that fits into a floppy or CD drive bay. ![]() Once an exotic gadget used only by die-hard, control-obsessed overclockers, mutiple-fan controllers are now made by many different well-known brands, and merchandised in clear plastic bubble packaging - a sure sign of its entrance into the mainstream consumer market. Fan controllers emerged as a stock item for case modders and PC hardware enthusiasts in the past year.
