Have this fan controller since I bought my old no longer found me (was a Scyte). Installation in the 5.25-inch bay went quite well so far, connect fan and temperature sensors and embarrassed clever is then a bit trickier. With further went a temperature sensor broken because you have quite careful because the are very sensitive. Then, when times connected all fans (up to 4) are kanns also go already. The fan can operate the knobs very good rules (better than my old where keys were still installed) Furthermore, the display easy to read and the temperature and speed display is separated by color. The knobs can be set according to the press into the housing of the fan control which is very helpful if you have a door in front for drive bays.
All one has to if you want a quiet chilled PC in particular.
