What is SpeedFan?

SpeedFan is a free and open-source software utility that monitors and controls the fans in your computer. It can be used to adjust the fan speed, monitor the temperature of your components, and troubleshoot cooling problems. SpeedFan is available for Windows, Linux, and macOS.

SpeedFan works by reading the temperature and fan speed data from the sensors on your motherboard. This data is then displayed in a graphical interface, which allows you to monitor the temperature of your components and adjust the fan speed as needed.

SpeedFan can be used to troubleshoot cooling problems by identifying which components are overheating and which fans are not working properly. It can also be used to improve the performance of your computer by reducing the temperature of your components.

Why is SpeedFan not detecting fans?

There are a few reasons why SpeedFan might not be detecting your fans.

  • The fans might not be connected to the motherboard. Make sure that the fans are connected to the motherboard correctly. The fan headers are usually labeled “CPU Fan”, “System Fan”, “Power Fan”, etc.
  • The fans might not be spinning. If the fans are not spinning, SpeedFan will not be able to detect them. Try turning on the computer and listening for the fans. If you do not hear any fans, there might be a problem with the fans or the fan headers.
  • The fan speed might be too low. SpeedFan requires a minimum fan speed of 200 RPM in order to detect the fans. If the fan speed is too low, SpeedFan will not be able to detect the fans.
  • The fan speed might be too high. SpeedFan can only detect fans that are spinning between 200 RPM and 10,000 RPM. If the fan speed is too high, SpeedFan will not be able to detect the fans.
  • The fan speed might be being controlled by a third-party software. If you are using a third-party software to control the fan speed, SpeedFan will not be able to detect the fans.

If you are sure that the fans are connected to the motherboard correctly, are spinning, and are within the speed range that SpeedFan can detect, then the problem might be with SpeedFan itself. You can try updating SpeedFan to the latest version or reinstalling the software. If that does not work, you can try using a different fan monitoring software.

Here are some other tips that might help you troubleshoot the problem:

  • Try disabling any overclocking software that you are using.
  • Try disabling any power saving features that you are using.
  • Try restarting your computer.
  • Try connecting the fans to a different fan header on the motherboard.
  • Try using a different fan.

If you are still having problems, you can contact the SpeedFan support team for help.
