Reboot if...

[sebastjan2]

Hello! I have one quick question since I cannot find anything useful on Google, I came here .
Is it possible to reboot PC, if GPU temperature drops under 40°C?
Thats all folks!

I'm sure it's possible, but you must have misstyped that question. Don't you mean reboot PC if GPU temp rises ABOVE 40⁰C?

[sebastjan2]

Nope. It was not typo. If it drops UNDER is what I ment

Do you currently have a method to get your gpu temp?
eg for my nvidia I can use ...

nvidia-settings -t -q GPUCoreTemp

....or when using the nouveau driver I can get a temp using lm-sensors.

Once you have a method to get temps would be fairly simple to write a bash script
to reboot below a certain temp.

Here's an example of a script running a command when a temp is exceeded.

To use the reboot command without sudo in a script, run.....

sudo chmod +s /sbin/reboot

root@local:~# aticonfig --adapter=all --odgt


Adapter 0 - AMD Radeon R9 200 Series
Sensor 0: Temperature - 35.00 C

Now it should reboot

EDIT!: The only thing is that i'm scared of loop. When PC will reboot, thing is that GPU will be under 40°...

So why do you want to monitor for a low temp?
Would you need to delay the start of the script to allow
computer to warmup sufficiently?
