Sensors - cpu_fan = 0 RPM (and no service script generated)
by Moun from LinuxQuestions.org on (#54TTS)
I get a similar situation described in a previous thread.
Before submitting an issue to the project GitHub page, I prefer confirm this is not an issue related to my installation. Installed package is the official lm_sensors-3.4.0-x86_64-1.
Running sensors-detect leads me to this result:
Code:Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `coretemp':
* Chip `Intel digital thermal sensor' (confidence: 9)
Driver `nct6775':

Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no): yes
Copy prog/init/lm_sensors.init to /etc/init.d/lm_sensors
for initialization at boot time.
You should now start the lm_sensors service to load the required
kernel modules./etc/sysconfig/lm_sensors contains :
Code:# [...]
# This file is sourced by /etc/init.d/
lm_sensors and defines the modules toWMON_MODULES="coretemp nct6775"However, I didn't find any lm_sensors.init file with the command below:
Code:find /{bin,dev,etc,lib,lib64,root,run,sbin,srv,sys,tmp,usr,var} -iname lm_sensors.initAfter reading sensors-detect, which is actually a Perl script, it seems this message is displayed if the script failed to find /bin/systemctl.
It may be the expected situation with Slackware. By the way, I added a line to load nct6775 in /etc/rc.d/rc.local:
Code:modprobe nct6775Once the module loaded a wild hwmon2 appears (I wonder why I have an eeepc-wmi entry, it's a desktop computer):
Code:/sys/class/hwmon/hwmon0 -> ../../devices/platform/eeepc-wmi/hwmon/hwmon0/
/sys/class/hwmon/hwmon1 -> ../../devices/platform/coretemp.0/hwmon/hwmon1/
/sys/class/hwmon/hwmon2 -> ../../devices/platform/nct6775.656/hwmon/hwmon2/Only hwmon0 and hwmon2 have fan informations. The alias hwmon0 seems to reference the cpu fan:
Code:/sys/class/hwmon/hwmon0/fan1_input
/sys/class/hwmon/hwmon0/fan1_label (contains "cpu_fan")The alias hwmon2 references 5 fans without labels.
But what bugs me is that the hwmon0/fan1_input file shows 0 RPM, among hwmon2/fan[4-5]_input ones, but I assume it's because those fans are not actually plugged for them.
Below summary outputted by inxi and sensors shows the same results, and several others fans (I only see 3 fans in my computer case).
