I'm sorry. I copied over the wrong lines here of course. After applying with "c"
the `fan_zero_rpm_stop_temperature` state is as follows (actually applies
the custom setting):

$ cat fan_zero_rpm_stop_temperature
FAN_ZERO_RPM_STOP_TEMPERATURE:
50
OD_RANGE:
ZERO_RPM_STOP_TEMPERATURE: 50 110

$ sudo tee fan_zero_rpm_stop_temperature <<< "65"
65

$ sudo tee fan_zero_rpm_stop_temperature <<< "c"
c

$ cat fan_zero_rpm_stop_temperature
FAN_ZERO_RPM_STOP_TEMPERATURE:
65
OD_RANGE:
ZERO_RPM_STOP_TEMPERATURE: 50 110

Sorry for any confusion caused.
Tomasz
