Hi, I wanted to set up fancontrol so I followed the Arch Wiki and installed m_sensors and ran
sensors-detectThis worked fine. However, one of the fans seems to be broken or off since I get this:
sensors
f71858fg-isa-0a00
Adapter: ISA adapter
+3.3V: 3.28 V
3VSB: 3.28 V
Vbat: 3.22 V
fan1: 1270 RPM
fan2: 972 RPM
fan3: 0 RPM ALARM
temp1: +35.6°C (high = +70.0°C, hyst = +60.0°C)
temp2: +24.2°C (high = +100.0°C, hyst = +85.0°C)
temp3: +41.6°C (high = +100.0°C, hyst = +85.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +37.0°C (high = +83.0°C, crit = +99.0°C)
Core 1: +34.0°C (high = +83.0°C, crit = +99.0°C)
Core 2: +36.0°C (high = +83.0°C, crit = +99.0°C)
Core 3: +34.0°C (high = +83.0°C, crit = +99.0°C)
radeon-pci-0100
Adapter: PCI adapter
temp1: +41.5°C (crit = +120.0°C, hyst = +90.0°C)As you can see, the third fan has zero speed. I actually opened up the computer to check and all of the fans seemed to be working so I guess the issue is either a sensor is broken or I made a mistake with lm_sensors somewhere.
Can anyone help me?

Sanity check - guessing this is a desktop computer: when you opened up the computer, does it actually have 3x fans inside (i.e. a cpu fan, a rear fan and a front fan) that are connected to the motherboard fan headers?
If yes, maybe lm_sensors doesn't support everything on the "f71858fg-isa-0a00" sensor that is shown in your output.
For instance, my laptop has a "temp2: +0.0°C " reading, which isn't correct, but everything's working as it should be.
You could report your findings upstream to the developers of lm_sensors.

Thanks for your reply.
Yes, it is a desktop computer and indeed it has three fans, all of them properly connected. When I opened it up, every fan was spinning at a normal rate so I too think the issue may be related to lm_sensors.
I should point out that I just got this computer from someone who was throwing it out and it is nine years old, so maybe that's the reason. It does have some great specs though... its performance is comparable to my 3 year-old laptop.
Anyway, I will certainly report this issue to the developers of lm_sensors.
In the meantime, is it safe to proceed with the configuration steps on this fancontrol ArchWiki guide?

Yes, but take particular notice of the "Warning" at the top of that page.
It might not be available due to age, but you could check if your machine is running the latest BIOS version as BIOS controls fans.
