Hello :-)
A lmsensors3.conf generated by pwmconfig resulted in fancontrol message
"Error: file hwmon0/device/fan4_input+hwmon0/device/fan1_input doesn't
exist".
The motherboard was an ASUS P8H67-V fitted with an S-Flex SFF21E case
exhaust fan (3 wire) connected to CHA_FAN2 and a stock Intel Core i3
processor cooler fan (4 wire) connected to CHA_FAN.
pwmconfig detected that the Nuvoton NCT6776F controlled both CHA_FAN and
CHA_FAN2 via pwm1 (pwm2 controls CPU_FAN; pwm3 seems not to be used).
The sensors3.conf generated by pwmconfig included this line:
FCFANS= hwmon0/device/pwm1=hwmon0/device/fan4_input+hwmon0/device/fan1_input
The space after FCFANS= is irregular but did not seem to cause any
problems for fancontrol.
Both hwmon0/device/fan4_input and hwmon0/device/fan1_input do exist:
root@CW8:~# ls -l /sys/devices/platform/w83627ehf.656/fan[14]_input
-r--r--r-- 1 root root 4096 2011-12-03 18:44
/sys/devices/platform/w83627ehf.656/fan1_input
-r--r--r-- 1 root root 4096 2011-12-03 18:26
/sys/devices/platform/w83627ehf.656/fan4_inpu
Further information: the processor cooler fan was connected to CHA_FAN2
instead of CPU_FAN because pwmconfig could not slow it below 1,100 RPM
when it was on CPU_FAN. Here's the pwmconfig output with the processor
cooler fan connected to CPU_FAN:
