    Increasing the voltage [4] over the default 12 V can be achieved by e.g. connecting the −12 V or −5 V power line instead of the ground wire in the fan connector, and by connecting the 5 V power line in the +12 V input of the fan connector. Through this procedure, 10, 17 and 24 V voltages can be achieved, with voltages exceeding 12 V being ...
