The Nexus FSA-75 is an easy way to make your case fan even more silent. Place the FSA-75 between the fan connector and the case fan, choose one of the three available cables and the fan speed is adjusted therefore makes less noise.
With the FSA-75 fan controller the fan can be set to three different voltages. The voltages available on the FSA-75 are 5V, ± 7V and 12V.
The FSA-75 is very easy to install. Just plug one end in the to the fan power connector and one of the other ends to the fan itself.
With the case fan connected to a lower voltage, the fan speed will reduce, this results in less noise.
Fan controllers, whether controlling single or multiple fans, can simply control the fan speed. Voltage regulators and fan resistors are simply other names for a fan controller. In some cases fan controllers can also monitor the temperature of the fan and various locations inside your PC. Using a front-mounted fan controller with temperature monitoring allows the quiet computer user to produce the quietest computer possible, while still maintaining a sufficiently cool environment for their PC components.
