As big as two DVD drives

The GateWatch takes up just as much room in the case as the CoolWatch. Although the fan controller is laid out to fit a 5.25" drive bay, it's thick enough to require two free neighboring bays for insertion. Its front panel display includes numerous temperature and fan monitoring elements. You also get four individual temperature sensors that you can deploy inside the case anywhere you like.

Various buttons provide access to individual readings available from this device. Repeated use of any single button cycles through all available (and related) sensor or fan indicator readings. You can also switch the temperature displays between Fahrenheit and Celsius degrees.
