Getting lm-sensors working on the Asus AM1I-A in Arch Linux

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/

fam15h_power-pci-00c4 Adapter: PCI adapter power1: 0.00 W (crit = 25.00 W)

k10temp-pci-00c3 Adapter: PCI adapter temp1: +13.8°C (high = +70.0°C) (crit = +70.0°C, hyst = +69.0°C)

it8603-isa-0290 Adapter: ISA adapter in0: +0.83 V (min = +1.10 V, max = +0.17 V) ALARM in1: +2.23 V (min = +1.86 V, max = +1.62 V) ALARM in2: +2.03 V (min = +0.14 V, max = +0.16 V) ALARM in3: +2.03 V (min = +1.49 V, max = +2.05 V) in4: +0.67 V (min = +3.02 V, max = +0.78 V) ALARM 3VSB: +3.34 V (min = +4.39 V, max = +5.11 V) ALARM Vbat: +3.17 V
+3.3V: +3.34 V
fan1: 1266 RPM (min = 200 RPM) fan2: 0 RPM (min = 600 RPM) ALARM temp1: +32.0°C (low = -37.0°C, high = +60.0°C) sensor = thermistor temp2: +36.0°C (low = -123.0°C, high = -97.0°C) ALARM sensor = thermistor temp3: -128.0°C (low = -112.0°C, high = +47.0°C) sensor = thermistor intrusion0: ALARM

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’ ```
