Closing WordsįanCtrl is a well designed open source application it may not work on every PC you run it on as some configurations may not be supported, but if it does, it does deliver. Activate it to display temperature and fan speed information as well as RAM and FPS in an overlay on the screen. The second feature that FanCtrl supports is an on-screen display. Supported modes are normal, silence, performance, and game. You need to enable 'automatic fan control' and may then assign modes to sensors and fans.

A click on the option opens a new configuration window. The first allows you to configure the program's automatic controlling of fans. The fan control program for Microsoft Windows devices supports two additional options. Other motherboards via LibreHardwareMonitorLib or OpenHardwareMonitorLib.You may use them to change the update interval from the default 1000ms, enable or disable the use of libraries and support for certain devices, and configure the program to start with Windows.Īs far as support is concerned, the developer notes the following components are supported: Raising the fan speed on the other hand may lower the temperature but increase the noise the fan makes.Ī click on options displays a number of settings. Lowering the fan speed may increase the temperature of the component and lower the noise of the fan at the same time. You could lower or raise the fan speed of a component using the fan control fields. Just click in a field and type to change the value.

You can rename device and fan names for better identification, and change the fan control value easily. The temperature of each component, as reported by the component or motherboard, and the fan speed is listed by the program. I ran it on several systems to get a feel for it it supports plenty of hardware components including processors, video cards, and motherboards. The program displays the temperature of components that it detected on start and the fan speed of those components. NET Framework 4.6 but can be run from any location.įanCtrl works similarly to Speedfan. For video card fans, I used MSI Afterburner, a free software for all video card manufacturers.įanCtrl is a free program for Windows. I used the free tool Speedfan about a decade ago to control fans on Windows PCs to reduce the noise these fans generated. While that is necessary to keep components from overheating, it is sometimes problematic because of the noise that these fans make.
