  * Note that the above descriptions are board-specific. Please see the board [http://www.gateworks.com/usermanuals Hardware User Manual] 'System Temperature and Voltage Monitor' section for details. Note also that Vin (Board Input voltage) is evaluated at the board's primary power supply input and offset by an estimated diode drop and thus may differ from your actual power supply within a volt or so.

 The fan controller temperature set points can be found in the {{{/sys/class/hwmon}}} directory along with the temperature and voltage monitor information (see previous section). The following examples show reading and writing to the fan set point register.
