What other features does SpeedFan offer besides controlling fan speed? Once installed, SpeedFan will automatically detect if your hardware is compatible and advanced features are presented. SpeedFan is able to control the fan speed of most fan makes and models, but this will ultimately depend on your motherboard's sensor chip and capabilities. Can SpeedFan control the fan speed of any fan? Be aware of that the fans stop around under 100 depending on your fan.SpeedFan is a hardware monitor software that can access temperature sensors, but its main feature is that it can control fan speeds - depending on the capabilities of your sensor chip and your hardware - according to the temperatures inside your PC, thus reducing noise and power consumption. If so you can control your fans by setting the PWM type to manual and setting a PWM value from 0-255. Hopefully your fans now show up in sensors. GRUB_CMDLINE_LINUX=‘acpi_enforce_resources=lax’ Make sure the instruction acpi_enforce_resources=lax is set in your grub configuration (/etc/default/grub). Google your chip id and there is a good chance to find what kernel module you have to load.Įxecute modprobe nct6775 to load the kernel moduleĪdd the line nct6775 to the file /etc/modules-load.d/nf In my case a Super I/O chip of the type VIA/Winbond/Nuvoton/Fintek found.īut sensors-detect fails with “unknown chip with ID 0xd42b” Trying family `VIA/Winbond/Nuvoton/Fintek'. (logical device B has address 0x290, could be sensors) Trying family `National Semiconductor/ITE'. This is usually safe.ĭo you want to scan for Super I/O sensors? (YES/no): Be careful and abort with CTRL+C after seeing the following output.Įxecute sensors-detect and follow the instructions until you see this: Some Super I/O chips contain embedded sensors. The following command can damage your system! The chance is low but it can happen. If you can’t see the fan states in sensors you have to detect them first and load a kernel module that fits to your chip. First you have to make sure your fans show up in “sensors”
