Cooling fan noise

[elvis 0]

Tinker Edge R is very interesting board, unfortunately cooling fan running at full speed all the time makes playing with this board very painful experience.

Is there any method to reduce fan speed? In fact it should be possible to run even with passive cooling most of the time, ToyBrick doesn't need active cooling at all. Maybe fan should be used only in case of temperature increase?

I have the same problem. Someone wrote a script (see below) to reduce fan speed when it is not necessary for tinker T, but I have problems on running it on Edge R. I already wrote to Asus and waiting for a reply.

Let me know if it works for you.

Hi onayg,

This code seems to be prepared for Asus Tinker, not Edge. It also requires additional circuit to be connected. In my opinion it will not work here ?

The only solution I've found until now is to disconnect fan, otherwise noise is too annoying for me. But during boot fan is running slower, so there seems to be some way to control rotation speed. Just I have no idea how.

Hi Elvis,

You could follow steps as below:

linaro@linaro-alip:~$ sudo -i
root@linaro-alip:~# echo 158 > /sys/class/gpio/export 
root@linaro-alip:~# echo 0 > /sys/class/gpio/gpio158/value <== Low Speed
root@linaro-alip:~# echo 1 > /sys/class/gpio/gpio158/value <== High Speed
root@linaro-alip:~# echo 158 > /sys/class/gpio/unexport 

Note:
1. Two-level controllable for the Fan Speed, Low and High.
2. The default Fan Speed is High.

Thank you for the answer, with low speed it's much better ?

Do you plan to document such "tricks" somewhere? I think that knowledge might be very for all Edge R users.

I share my codes on Gist:

This is a simple script and service setup that allows your Debian OS can monitor the temperature of the SoC regularly and then control it to be high or low speed automatically through the GPIO. 

I have not encountered any problems so far
