How to set you up?

[z36r2850o]

Hello. I can't figure out how to set up fan2go. I am facing an error when I try to execute the `sudo fan2go. Here is what I get in response:

A little information.

 SUCCESS  Config looks good! :)

I am using archlinux and fan2go built from the AUR. Please tell me how to fix this?

Hmm looks like fan2go cannot read the RPM of the fan, does the fan connector and the fan itself support it? Can you see RPM values when running sensors?

[z36r2850o]

sensors

asus-isa-0000
Adapter: ISA adapter
cpu_fan:     2100 RPM
temp1:        +45.0°C  

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +48.0°C  (high = +87.0°C, crit = +105.0°C)
Core 0:        +48.0°C  (high = +87.0°C, crit = +105.0°C)
Core 1:        +47.0°C  (high = +87.0°C, crit = +105.0°C)

acpitz-acpi-0
Adapter: ACPI interface
temp1:        +45.0°C  (crit = +108.0°C)

does the fan connector and the fan itself support it?

Don't know how can I check it?

[z36r2850o]

If you run fan2go detect then everything shows, but it is enough to run sudo fan2go and everything is empty again. The sensors command now shows:

asus-isa-0000
Adapter: ISA adapter
cpu_fan:          N/A
temp1:        +53.0°C  

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +54.0°C  (high = +87.0°C, crit = +105.0°C)
Core 0:        +54.0°C  (high = +87.0°C, crit = +105.0°C)
Core 1:        +54.0°C  (high = +87.0°C, crit = +105.0°C)

acpitz-acpi-0
Adapter: ACPI interface
temp1:        +53.0°C  (crit = +108.0°C)

I guess something goes wrong when fan2go tries to set the pwm_enable value, but the error is not logged correctly :( I will try to make some adjustments surrounding this.

[markusressel]

@z36r2850o I have made some changes for #116 as well, can you retest?

I am closing this because of inactivity. Feel free to reopen if necessary :)
