![]() So be careful with these programs and always monitor your system's parameters. I'm not interested in actually testing this failure condition, though. Therefore, it should be possible for the fan to be turned off and remain off even under high load if the program crashes, gets killed or otherwise exits without resetting the fan mode back to automatic. Manual mode means the fan speeds are set manually. ![]() Automatic mode means the fans are controlled by the computer's own embedded controller. On these laptops, fans apparently have two modes of operation: automatic and manual. The program is GPLv3 and talks to the laptop's embedded controller directly instead of using or exposing any sysfs interfaces. I've been in contact with them and it appears they just released their fan control application. I just learned about which allows a fan control curve to be specified, but it has some limitations, like I can't see how to monitor different specific temperatures for one fan, it is designed to use I/O ports directly instead of the existing kernel interface, the configuration seems tedious, and it uses Mono.ĭevelopers from Tuxedo have been working on fan control drivers and user interface for their Clevo-based laptops. But if you want to control fan speed, only very rudimentary tools seem available, like the fancontrol shell script. If you want to just see temperature, lm-sensors will show you that in a friendly way. User mode software is needed to actually set fan speeds based on current temperatures. ![]() However, this merely provides an interface for reading temperature or writing PWM values. ![]() This stuff is available via the /sys file system, for example fan control via /sys/devices/virtual/hwmon/hwmon2/pwm1. The Linux kernel supports a wide variety of temperature monitoring and fan speed control. ![]()
