G15 SpeedFan

The G15 SpeedFan application was designed to be a small tool that will work with any Logitech G15 keyboard and displays realtime temperature, fan speed and voltage information from SpeedFan.
It is a breeze to configure, and only requires that you have the Logitech GamePanel Manager software running. The download (below) comes with a default configuration file that will work with most computers, and instructions on how to change it if required.
You can set high and low values and if the temperature, fan speed or voltage goes outside that range the value will be displayed in bold on your LCD screen. Very helpful for long gaming sessions if you don’t want your computer to overheat.
Column Offsets:
There are 3 values listed, each value is the pixel offset of each column. For example, the first value "30" means that the first column will be centred around column 30. Play around with these values until you get everything lined up the way you want.
Temperatures:
There are 4 sub-sections here. Each subsection contains 4 values. The first value is the display name. You can set this to whatever you want to appear on your G15 LCD. The next value is the 0-based index number of the SpeedFan value. To get this index number just open SpeedFan and count how many items down the list an item is. For example, if SpeedFan shows your CPU temperature as the 3rd item listed, then it would be index number 2. (0, 1, 2). The next value is the minimum value threshold. If the value for this sensor every drops below this value you set it will be displayed in bold on your G15 LCD. Set this value to -1 to disable this feature. The 4th item in this sub-section is the maximum value threshold. It works the same as a minimum value except it will bold the value when it goes over this threshold.
Fans and Voltages:
Configuration for these sections is the same as for TemperaturesSystem requirementsLogitech G15 keyboard
