Controls the speed on your system fans for CPU and GPU
FanCtrl is a software that allows you to automatically control the fan speed on your PC.
The free tool FanCtrl provides you with all information about your mainboard/processor/graphics card fan and offers you the possibility to control it precisely. In this way, you always have an overview of the PC temperature and can influence it in a targeted manner.
You can use the so-called on-screen display (OSD for short) to display certain values graphically on the Windows desktop.
You can also use this useful tool to create profiles so that the fan speed can be adjusted automatically. Simply set the desired speed at a certain temperature in your computer case and the program reads the system's internal thermostat and adjusts the speed of the fans if necessary.
