Frequently Asked Questions

How does SpeedFan work?

The SpeedFan application runs in the system tray like any other Windows application. By default, it doesn’t do anything until certain conditions are met, such as a specific CPU temperature or enough drive space used. As soon as the program runs, the fan will start to reduce the temperature, or you will get a pop-up alert.

What RPM should my CPU fan be?

Depending on your CPU fan stock, you could set it to 70 percent or even higher RPM. It is ideal for running the fan at 100 percent RPM if your CPU temperature is 70C. A CPU fan should spin at 50 percent of its total RPM at 50 to 55 degrees Celsius.

How does computer fan speed increase?

In order to actively cool the CPU, computers run their fans at high RPMs when high-end games and power-consuming software are utilizing them.
