As of 04/2014 version 3.3.5 of lmsensors doesn’t yet support the ITE IT8623E Super IO on the Asus AM1I-A meaning we can’t get fan speed and temp readouts. Support was added in this changeset so hopefully a new version will be released soon.
To get this working in Arch Linux, I did the following:
In Arch, SVN trunk lm-sensors can be built using the following AUR package https://aur.archlinux.org/packages/lm_sensors-svn/
After installing it, run sensors-detect(keep hitting enter saying yes to all the defaults), it should now detect the IT8623E as well as the temperature sensors built into the CPU
Trying family `ITE'... Yes Found `ITE IT8623E Super IO Sensors' Success! (address 0x290, driver `it87')
- With kernel 3.14, the it87 module needs to be force loaded:
$ modprobe -vv it87 force_id=0x8603 modprobe: INFO: custom logging function 0x409b50 registered insmod /lib/modules/3.14.2-1-ARCH/kernel/drivers/hwmon/it87.ko.gz force_id=0x8603 modprobe: INFO: context 0x15b2290 released
- On running sensors, you should now get some output from the IT8623E:

Partial success! Unfortunately the values look fairly crazy, so we’ll need to tweak the sensor config.
- To load the module with that parameter on every boot, add a new .conf file in /etc/modprobe.d containing:
options it87 force_id=0x8603
as per https://wiki.archlinux.org/index.php/kernel_modules#Setting_module_options
- We can also enable sensorsd to start on every boot:
$ systemctl enable sensord ln -s '/usr/lib/systemd/system/sensord.service' '/etc/systemd/system/multi-user.target.wants/sensord.service'
