Makes Odroid XU3 Lite fan silent on idle load

systemd init script

As most modern distributions are switching to systemd, it might be appropriate to add a service for it.

XU4: Fan spins even when the temperatur is so low that the fan shouldn't

Hey there,

thx a lot for your work!

I have installed the script on my XU4-device and is is working well - with one exception:

When the cpu-temp ist below the 55 degrees then the fan shouldn't work and the variable fan_speed is set to the vaule 2:

elif (( ${current_max_temp} >= 55000 )); then
new_fan_speed=30
else
new_fan_speed=2

But in my case the fan spins for a short moment (not even a second), makes maybe 2 to 3 spins and stops. Then there is another short moment (not even a second too) where the fan is in stop-mode and then he spins again 2 to 3 spins. This goes on and on and on.
Shouldn't the fan stop and doing nothing when the cpu-temp ist below 55 degress according to your script?

What can I do do stop the fan from this 2-3-spins-stop-cycle every "half second"?

Any hint?

Thx a lot, mike

squeaking sound

Hi!

tried your script on the new XU-4 which is said to be XU-3 compatible. Use it on Ubuntu 15.04.
$uname -a ->
Linux odroid 3.10.82-39 #1 SMP PREEMPT Fri Jul 10 17:47:37 BRT 2015 armv7l armv7l armv7l GNU/Linux

Instead of the fan noise I know get a high frequency squeak (but no fan noise as it stops turning)

Disable syslog information

Hi,

Do you know how to disable fan control information from syslog ? I found that these messages are from kernel but I do not know how to turn it off.

Please help.

Works on XU4

If I changed odroid_fan.14 to odroid_fan.13 it works on Odroid XU4 too.

FAN_MODE_FILE="/sys/devices/odroid_fan.13/fan_mode"
FAN_SPEED_FILE="/sys/devices/odroid_fan.13/pwm_duty"
