HC4 fancontrol not working again

Hi there,

I have HC4 and happily running DietPi for last 2 years but recently I have noticed that fan is buzzing to much and now I see after running sensors that it is around 3000rpm constantly even that temp is only 46.8C (or around):
`root@DietPi:~# sensors
pwmfan-isa-0000
Adapter: ISA adapter
fan1: 3046 RPM

cpu_thermal-virtual-0
Adapter: Virtual device
temp1: +46.6°C

ddr_thermal-virtual-0
Adapter: Virtual device
temp1: +47.5°C`

my fanconfig which worked for so far good but not anymore:

ty# !!!USE AT YOUR OWN RISK!!! Configuration file generated by pwmconfig
INTERVAL=10
DEVPATH=hwmon0=devices/virtual/thermal/thermal_zone0 hwmon2=devices/platform/pwm-fan
DEVNAME=hwmon0=cpu_thermal hwmon2=pwmfan
FCTEMPS= hwmon2/pwm1=hwmon0/temp1_input
FCFANS= hwmon2/pwm1=hwmon2/fan1_input
MINTEMP= hwmon2/pwm1=45
MAXTEMP= hwmon2/pwm1=55
MINSTART= hwmon2/pwm1=30
MINSTOP= hwmon2/pwm1=30
MINPWM= hwmon2/pwm1=10
MAXPWM= hwmon2/pwm1=150

After running pwmconfig:

Found the following devices:
   hwmon0 is cpu_thermal
   hwmon1 is ddr_thermal
   hwmon2 is pwmfan

Found the following PWM controls:
   hwmon2/pwm1           current value: 0

Giving the fans some time to reach full speed...
Found the following fan sensors:
   hwmon2/fan1_input     current speed: 0 ... skipping!

There are no working fan sensors, all readings are 0.
Make sure you have a 3-wire fan connected.
You may also need to increase the fan divisors.
See doc/fan-divisors for more information.

My current kernel is 6.6.65-current-meson64

Any help please?
