thinkfan.service won't start

[Guyv-dev]

Hi,
I have T14 gen3 and tried to work with Thinkfan, but I can't make it start. I am running pop_os.
my configs:

/etc/modprobe.d/thinkfan.conf:

options thinkpad_acpi fan_control=1 experimental=1

/etc/thinkfan.conf:

sensors:
  # GPU
  - tpacpi: /proc/acpi/ibm/thermal
    indices: [1]
  # CPU
  - hwmon: /sys/class/hwmon
    name: coretemp
    indices: [2, 3, 4, 5]
  # Chassis
  - hwmon: /sys/class/hwmon
    name: thinkpad
    indices: [3, 5, 6, 7]
  # SSD
  - hwmon: /sys/class/hwmon
    name: nvme
    indices: [1, 2, 3]
    correction: [-5, 0, 0]
  # MB

    name: acpitz
    indices: [1]

fans:
  - tpacpi: /proc/acpi/ibm/fan

levels:
  - [0, 0, 37]
  - [1, 35, 42]
  - [2, 40, 45]
  - [3, 43, 47]
  - [4, 45, 52]
  - [5, 50, 57]
  - [6, 55, 72]
  - [7, 70, 82]
  - ["level full-speed", 77, 32767]

/etc/default/thinkfan:

# Additional startup parameters
DAEMON_ARGS="-q"
THINKFAN_ARGS="-c /etc/thinkfan.conf"

cat /proc/acpi/ibm/fan:

status:		enabled

level:		auto
commands:	level <level> (<level> is 0-7, auto, disengaged, full-speed)
commands:	enable, disable
commands:	watchdog <timeout> (<timeout> is 0 (off), 1-120 (seconds))

i am getting:

there has been some naming hops in hwmon module in recent kernels. You have to adjust thinkfan.conf to follow it
