Here is my varyfan.conf
#
# Varyfan configuration file
#
# The non-comment parts are currently fragile.
# The format is strictly:
# Variable<space>=<whitespace>VALUE
# where Variable is case sensitive, and it's up to you to verify that
# the VALUE is in the correct range, <space> a single space, and
# <whitespace> is any combination of spaces and tabs.
#
# The varyfan.conf.suggested file contains the defaults.
#
# Extra debugging output. 0 = off(default), anything else = on.
#Debug = 0;
# The pseudo-files for the CPU and case, for PWM (fan speed), and temperature.
# They are provided by the lm-sensors package. Install that and find a
# directory that has all the required files.
