The default Trixie install does not include the NCT6799 module required
to read sensors on the newer B850 series chipset motherboards.
For users with B850 chipset motherboards (ASUS TUF Gaming B850-E WIFI
tested), the standard sensors-detect may not find hardware monitoring
support.
Solution:
sudomodprobe nct6775
sensors
This loads the NCT6799 Super I/O monitoring chip and provides:
* Fan speed monitoring (fan1-fan7)
* PWM control channels (pwm1-pwm7)
* Multiple temperature sensors (SYSTIN, CPUTIN, AUXTIN0-5)
* Voltage monitoring
Make permanent:
echo "nct6775" | sudo tee -a /etc/modules
I tested this with AMD Ryzen 7 8700G, ASUS TUF Gaming B850-E WIFI,
Debian Trixie, kernel 6.12.41
Note: CPU fans must be connected to motherboard headers (not case
controller boards) to appear in readings.
