![]() Many of these modules require you to add acpi_enforce_resources=lax to the kernel command line to load. This often results in sensors being able to report various temperature and voltage readings, and the fancontrol script ( packaged separately in Debian/Ubuntu ) can be configured to manipulate the fan speed in response to the temperature readings. You run sensors-detect and it will probe for known controllers and can configure the correct driver to be loaded to manipulate it. I would like to have a tool to test fan speed in command line, not only CPU fans. Many of these hardware controllers can be detected by the lm-sensors package. 5 I've to manage 50 workstations of different brands, mostly DELL T76 and HP Z800. Generally the bios ACPI tables don't provide the fan interfaces and just leave it up to a hardware controller to manage. You might look in /sys/class/thermal and see if there are any fans that show up under there and if they can have their settings changed. Unfortunately, I have yet to see a single bios vendor actually comply with the standard. Have all of them controlled by a single smart entity, and start thinking about cooling and noise as a system-wide concern. Say goodbye to the 'silo' approach of using multiple softwares to control your different fans. Fans are supposed to be managed by ACPI, which allows the kernel to cooperate with the bios to monitor temperature and adjust the fan speed automatically using bios provided rules. Fan Control has extensive support for a variety of motherboards, GPUs, and other hardware, like AIOs. ![]()
