Script for Fan Speed Control

[nsaha]

Ok, I found how to save my configuration.
In nvidia-gui.py, line 119 & 120:

x_values = [0,  55, 59, 61, 63, 64, 65, 68, 80, 100, 110] #temp
y_values = [15,  16, 17, 32, 63, 83, 92, 94, 98, 99, 100] #speed

and at the line 66:

first = [0,10]

I start at 10%, but the bios of my card start at 28%. So my minimum speed is 28%.
To modify this, I've seen this thread, but I'm a little afraid to change the bios of my card (waranty etc..)

To start your software, I've wrote this script to have a log file:

#! /bin/bash
exec >/home/nsaha/.Nvidia_control_fan/start_fanspeed.log 2>&1
python /home/nsaha/.Nvidia_control_fan/nvidia-gui.py

But I still have the window at startup
Anyway, this is an excellent software, thank you !

Thank you!
Good job in modifying the script!
I thought that a limit of 30% could be acceptable, but I was thinking of a gaming configuration

But I still have the window at startup

If I have understood, you want the script to run without the GUI, right?

Yes, but I've found a solution: I've commented the line 222 like this

#chart.show()

And the script works without the GUI.
With this script and Psensor, I can verify that all is fine

Ok

I actually use a simple bash script to do the work, but yours are far more sophisticated, great job!

The thing is the method we use is the same, nvidia-settings is the (only possible?) responsible to tweak the fan.

However last days I tried to make some CUDA computations over tty, necessarily without a running X server. And what happens is that [gpu:0] and [fan:0] don't exist anymore, since there is no X servers/displays, thus nvidia-settings -a ... doesn't work.

What you think about? Any ideas to set fan speeds without X servers?

[MisterPup]

Thank you!
No I'm sorry, I don't know how to do it. I've done some tests and, as you said, nvidia-settings doesn't work.
I've taken a look on the web, and I've found this outdated article

Also I've found your question on the Nvidia forum, have you tried the solutions proposed there?

[homerobono]

Thank you, that worked

It doesn't allow you to auto adjust fan speeds, but to set a fixed speed and the GPU to hold this parameter. Although, this seems to be the best that can be done with the faulty geforce products line.

I don't understand why nvidia doesn't have a proper heat management script inside the BIOS or the driver, so I'll keep watching for user mods to a lower level implementation oh these hacks. Please let me know if you find any driver related solution.

Perfect!
Ok, you too if you find it first
