You can also use system monitoring tools such as Core Temp and HWMonitor to monitor and adjust the fan speed. The main window will bring the RPM of the fans and will give you all the information about the temperatures of the motherboard chip, processor, hard disk, and so on. Now the question is how to inquire about the temperatures of different stuff of the PC. Once you are done with the downloading, start installing the software for using that.Īfter the installation process, give some time to the software and let it read all the important details about your PC. For using the speedfan software you have to download the latest version of that software from its official site. The third wire provides feedback on the actual RPM of the fan.SpeedFan is software for controlling the CPU fan speed. Fans with 4 wires are controlled through pulse width modulation (PWM), in theory a more efficient way of controlling the fan speed. See Lm_sensors for generic details.įans with 2 or 3 wires may have voltage regulation: higher voltage (typically up to 12 Volt) results in higher rotation per minute (RPM). Specific hardware may have specific needs with respect to kernel configuration. Fans that allow their speed to be controlled.A motherboard capable of regulating fan speeds.A BIOS that allows users to control the fan speed.Higher temperatures cause more wear on the electronics, resulting in a shorter lifespan.Ĭontrolling fan speed is not supported on all computers.What if the program controlling the fans fails? The computer could overheat and parts could be destroyed.There are two risks when manually controlling fan speeds: It is generally considered more safe to have the BIOS or dedicated hardware control the fans.
