VIM3 fan control

[TheCoolest]

You can install netdata via entware (there’s a thread about it)
Or you can run cputemp from ssh.
And of course in Kodi GUI you can see temperature in Hardware tab under system information

[timfolk]

Thanks TheCoolest. I’ll look into those options.

You can install netdata via entware

Further option using docker

Is there a way to see the temps?

SSH and run command below which continually monitors Temp. When Fan Kicks in
you can see the temp live in your SSH session.

echo "cat /sys/class/thermal/thermal_zone0/temp" > temp 
chmod +x temp 
watch ./temp

[timfolk]

Thanks, kostaman.
I was thinking SSH would be the easiest way look into it. I’m not near a PC when I watch something though, so I’d have to get up and look. I’ll have a look at this though. Or maybe map a key to Kodi’s info if that’s possible so I can just open that while watching.

Nice, thanks.
btw, I posted on another issue some weeks ago and it was moved to the Hardware thread and had no responses.

Network unreachable

Using the 20200210 currently. I have a small issue that seem to come and go with updates. Not sure if it’s build related: I usually leave the Vim3 on a network shared location (where I have videos I play) when I send it to suspend via CEC. A lot of the times when it wakes up on TV power (it sometimes does and sometimes I have to press the power button), It pops a “Network unreachable” error and goes back to Videos root. From there it has no problem to browse to my saved network locations.

Any suggestions on that?

echo “cat /sys/class/thermal/thermal_zone0/temp” > temp chmod +x temp watch ./temp

running this now. V3 is idle. it shows 40000-40500. Started a vid and it’s averaging at about 41700-41900 at the beginning and now climbing towards 43000.
I’m not sure what sort of temp metric this is. I’ll check it out if/when the fan kicks in.

[Tim_Taylor]

Create the file temp using vi or nano and insert this commands:
cpuTemp0=$(cat /sys/class/thermal/thermal_zone0/temp)
cpuTemp1=$(($cpuTemp0/1000))
cpuTemp2=$(($cpuTemp0/100))
cpuTempM=$(($cpuTemp2 %$cpuTemp1))
gpuTemp0=$(cat /sys/class/thermal/thermal_zone1/temp)
gpuTemp1=$(($gpuTemp0/1000))
gpuTemp2=$(($gpuTemp0/100))
gpuTempM=$(($gpuTemp2 %$gpuTemp1))
echo CPU Temperatur “= “$cpuTemp1”.”$cpuTempM"°C"
echo GPU Temperatur “= “$gpuTemp1”.”$gpuTempM"°C"

save the file
chmod +x temp
watch -t -n 5 ./temp
Shoes temperatur from CPU and GPU in celsius

[timfolk]

Thank you. I will try it.
So 43000 is 43c (43.000)?

[Tim_Taylor]

@timfolk

So 43000 is 43c (43.000)?

No, it´s not only division by 1.000

[timfolk]

OK.

GPU Temperatur “= “46”.”7°C

looks like it’s running with your code. I think you left out a slash so I changed it to watch -t -n 5 ./temp.

[Tim_Taylor]

@timfolk

I think you left out a slash

Sorry, I edit my post

[timfolk]

Ran the script for a few hours while watching last night. Did not notice any sudden fan action. It stayed on those values most of the time:

CPU Temperatur “= “44”.”9°C
GPU Temperatur “= “46”.”3°C
CPU Temperatur “= “45”.”0°C
GPU Temperatur “= “47”.”3°C
CPU Temperatur “= “44”.”8°C
GPU Temperatur “= “46”.”1°C

Hello, i have installed the 3705 fan on khadas vim3 with coreelec OS, but it not work. How can i active it?

[eviltrooper]

also bought the 3705 FAN… but its not working…
seems i2c-tools are not installed…

[eviltrooper]

i can activate the Fan on Kodi… how this works without i2c-tools?
i want to use this on emuelec as well…

[vpeter]

i2c-tools are part of system-tools addon.

Maybe this could help too: service.coreelec.settings/hardware.py at coreelec-19 · CoreELEC/service.coreelec.settings · GitHub
seems it writes some values to /sys/class/fan nodes.

[eviltrooper]

Ahh. CoolMaybe this works for emuelec… j

[eviltrooper]

Yes it works…
