I want to know whether the fan of my laptop is on via software. I load fan.ko without complaint. That creates /sys/module/fan/ and /sys/bus/acpi/drivers/fan/ . /sys/module/fan/initstate contains the word 'live' - a good sign. But I can't find a file that contains the current state. fan.c tells me the fan is either on or off and that it would record this with a 1 or 0 in a file called state, but I can't find that file.
The only subdirectory in /proc/acpi is button; I think /proc/acpi has been deprecated.
I used to be able to do this on my old Thinkpads with some software written for them.
AFAIK lm-sensors is the package you need to monitor fans and temps etc. This link should help -->http://lm-sensors.org/wiki
I think lm-sensors is installed if you do a full install. To find out if its there you can as root run the command 'sensors-detect'. It will probe your system and let you know what is found. Once lm-sensors is configured ( with sensors-detect ) you can add plugins for various desktops and display fans, cpu temp, etc. I use xfce and have the fans displayed.
Note that lm-sensors does not support every piece of monitoring hardware out there, so it may not work based on hardware not found.
lm-sensors is installed. sensors-detect finds no sensors it can use. inxi tells me that. I suspect that the fan module loads but can't detect fan status.

Just to see what options are available in inxi since you now have it installed.
Code:
inxi -h
Shows all the different command options that can be used. I am posting right now in Racy 5.2.2 Puppy Linux which is pretty limited in what can be installed as far as sensor modules go. I know I have fan sensors on this laptop but Puppy won't show rpm on fans but In AntiX I can.

sh-3.00#
This is a recent install so like you. I still have some searching/configuring to do to get Puppy to read fan speeds.
So. I installed hddtemp from source since in Puppy Linux. Kinda like Slackware in that respect. But. No joy with fan speed either doing that. Just posting the info. I did make from inside hddtemp source folder. Also downloaded hddtemp.db (data base). Puppy runs as root so easy to compile that way in a sense.

Funny thing is. In my previous post with sensors command all my temps showed OK. This was kinda a shot in the dark to see if hddtemp would help in seeing fan speeds in Puppy. So, Like you

I looked there in Puppy and saw the same as you, 'live'. This is a Acer Laptop 5534 dual core. Probably only has a chassis fan, no cpu fan like my desktop (temperature readouts reminded me to plug in the usb laptop cooler pad ) . So I still have some digging to do like you to see what else I can find.
inxi -h returns 117 lines of information. -s reports fan status, which returns N/A. I think I'm thinking about the chassis fan: it's the one I can see on the bottom rear of the case that I can feel blowing occasionally
/sys/devices/virtual/thermal has 4 directories cooling_device0/ cooling_device1/ cooling_device2/ thermal_zone0/ ; 0 and 1 are 'Processor' type; 2 is LCD type; the type of thermal_zone0 is 'acpitz' - whatever that means (acpi thermal zone?). The temp file in thermal_zone0 is the value the coretemp module returns. Perhaps one of the other files in thermalzone0 is the fan status.
Would you 2 kind persons do me the favor of telling me if you have either of these 2 files:
fan.c creates a device with ID PNP0C0B . I see that it never appears in any log file or in /sys/devices/LNXSYSTM:00 where PNP0C0? for lots of other digits appear. It appears my computer doesn't report its fan status.
It definitely works: when the temp reaches 55 degrees the fan comes on and the temperature drops.
