Please verify that all fans have returned to their normal speed. There is either no fan connected to the output of hwmon2/pwm6, Note: If you had gnuplot installed, I could generate a graphical plot. Would you like to generate a detailed correlation (y)? y The pwm outputs connected to the fan connectors,ĭid you see/hear a fan stopping during the above test (n)? Or the connected fan has no rpm-signal connected to one of There is either no fan connected to the output of hwmon2/pwm1, If you do not want to do this hit control-C now!!! This may cause your processor temperature to rise!!! Warning!!! This program will stop your fans, one at a time, Hwmon2/fan2_input current speed: 2054 RPM Giving the fans some time to reach full speed. Hwmon2/pwm5 is currently setup for automatic speed control. Hwmon2/pwm4 is currently setup for automatic speed control. You want to setup this output for manual control? (n) It is more efficient and it reacts faster. In general, automatic mode is preferred over manual mode, as Hwmon2/pwm3 is currently setup for automatic speed control. Physically verify that the fans have been to full speed However, it is ** very important ** that you The program will attempt to restore each fan to full speedĪfter testing. We will attempt to briefly stop each fan using the pwm controls. Note that many motherboards do not have pwmĬircuitry installed, even if your sensor chip supports pwm. This program will search your sensors for pulse width modulation (pwm)Ĭontrols, and test each one to see if it controls a fan on The script tests the individual fans and can then assign them to a temperature sensor with corresponding threshold values: ĭo you want to add these lines automatically to /etc/modules? (yes/NO)yes sudo pwmconfig To load everything that is needed, add this to /etc/modules: #-cut here- # Chip drivers coretemp nct6775 #-cut here- If you have some drivers built into your kernel, the list above will contain too many modules. (YES/no): YES Do you want to scan for Super I/O sensors? (YES/no): YES Do you want to probe the I2C/SMBus adapters now? (YES/no): YES Sudo service fancontrol start Reading out the temperaturesĬommand: sensors Setting the threshold values sudo pwmconfig Ubuntu 20.04: There are no pwm-capable sensor modules installed sudo sensors-detectĭo you want to scan for them? This is totally safe.
Installing fancontrol sudo apt-get install fancontrol lm-sensors Using the service fancontrol the speed of the fan can be linked to any sensor and any threshold and controlled automatically.
In the BIOS I could set the speed, but the automatic mode did not work properly. After I installed a fan in my NAS, it always ran at top speed.
