Our PCs generate a lot of heat during their operation, a heat that must be controlled and eliminated since otherwise it can negatively affect the operation of the equipment, in the most serious cases it can even produce blackouts and irreversible damage. SpeedFan is a simple tool that allows us to adjust the speed of our PC fans to our liking.

Why do PCs heat up?

The explanation is very simple and has to do with the laws of thermodynamics, energy is neither created nor destroyed, it is only transformed. In an ideal world, the energy efficiency of the components of our PC would be 100%, with this, all the electricity consumed would be used and nothing would be wasted in the form of heat. Unfortunately this is impossible, our PCs have an energy efficiency of less than 100% which means that not all the energy is used, the part that is not used is lost in the form of heat and therefore the components heat up.

Control the temperature of your PC with SpeedFan

Many of our readers will be used to hearing the name of applications like MSI Afterburner, a great tool but it has the limitation that its action is limited only to the graphics card. SpeedFan is a much more widespread application that allows us to monitor the temperature of all the components of our PC, additionally it allows us to control the speed of rotation of all the fans, including those of the CPU and those of the chassis.

Best coolers, fans and liquid cooling for PC

The speed at which the fans need to rotate is proportional to the workload of the system and its temperature, normally the motherboard is in charge of managing it but sometimes it may not be as effective as we would like and that's where as users we can intervene.

In the SpeedFan sections we find information about the real-time temperature of the components of our system and the speed of the fans also in real time. We can modify the speed of rotation directly or configure operating profiles so that it adjusts automatically according to the performance and temperature of the components of our PC.
