Framework 13 laptop fan constantly at max speed regardless of CPU temp

I have had arch installed on my Framework 13 laptop for a few months with no issues however the CPU fan has recently started going at full speed regardless of CPU temp.

After running sensors-detect and sensors my output is:

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +29.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:        +26.0°C  (high = +100.0°C, crit = +100.0°C)
Core 1:        +26.0°C  (high = +100.0°C, crit = +100.0°C)
Core 2:        +27.0°C  (high = +100.0°C, crit = +100.0°C)
Core 3:        +25.0°C  (high = +100.0°C, crit = +100.0°C)

                       (crit = +84.8°C)

acpitz-acpi-0
Adapter: ACPI interface
temp1:        +31.8°C  

Following the guidance of https://wiki.archlinux.org/title/Fan_speed_control I attempted to increase the fan divisor by inputting

chip cros_ec-isa-0000
set fan1_div 4

in /etc/sensors.d/fan-speed-control.conf however I get the error

Error: File /etc/sensors.d/fan-speed-control.conf, line 1: Parse error in chip name

I have also tired using the fw-ectool-git package but when I use the commands the outputs seem correct but no change is actually made
