Best Linux alternatives to SpeedFan

What is SpeedFan?

SpeedFan is a Windows utility that lets users read sensor data and adjust fan curves to keep hardware cool. It’s popular among hobbyists, overclockers, and anyone who wants fine‑grained control over cooling without buying a dedicated hardware controller.

The program is distributed as freeware, with the source code not publicly released. Users can download and use it without paying, but it runs only on Windows.

Linux users often look for a replacement because they need similar temperature monitoring and fan control on their native OS, and SpeedFan does not run there natively.

What a replacement for SpeedFan must do

• Read CPU, GPU, and motherboard temperature sensors
• Adjust fan speed curves manually or automatically
• Display voltage and power usage information
• Support for multiple fan controllers and PWM headers
• Provide real‑time graphs or logs of sensor data
• Run with low system overhead

Can you run SpeedFan on Linux?

There is no native Linux version of SpeedFan. The usual approach is to use fancontrol, a command‑line tool that works with the lm‑sensors framework. Some users run SpeedFan under Wine, but fan control rarely works through Wine because it needs low‑level hardware access. No web version exists.

Which alternative should you choose?

If you need a simple graphical interface, consider Psensor for monitoring and combine it with fancontrol for PWM control. For scriptable, fine‑tuned fan curves, fancontrol remains the most direct Linux equivalent.

Moving your SpeedFan files and habits

SpeedFan does not store complex project files; it reads sensors directly from the hardware. To move to Linux, install lm‑sensors, run sensors-detect to expose the same hardware readings, then configure fancontrol with the generated config file. No data export is required.
