This unit was installed in a generic midtower case with 1 80mm intake fan, one 80mm rear exhaust fan behind the cpu area and dual exhaust fans in a Powmax/Leadman 300w PS. The other system specs were MSI KT7 Pro2A, Athlon 1.0 @ 1.1 A 1.85v, Radeon LE. The unit fit easily into the 5.25 bay and sensors and fan leads reached all interior area of the case. Before you install this unit, you really need to spend some time deciding where each sensor/fan pair will go. The sensor lead headers are in one bank of 8 and the fan power headers are installed in 2 banks of 4, but one bank of power headers is adjacent to the sensor leads and makes it a very tight fit, and difficult to move the leads around once they are installed. The unit needs to be completely cabled before it is fully inserted into the 5.25 bay. I installed the unit with a sensor between the hs/f and the cpu, a sensor in the top of the case, a sensor on the video card, and a sensor on the primary HDD. The video card only employs passive cooling, so I inserted an 80mm case fan between the video card and the modem in the next slot for test purposes.

The unit powered up with the system and immediately began cycling through the 8 temperature channels. As each temperature is displayed, an icon shows whether a fan is running on that channel. The unit is programmed through a set of buttons on the front panel. I first tried to program it without referring to the manual, just to see how intuitive the controls were, but eventually resorted the the manual, which provides straightforward explanations and diagrams for programming the unit.
