Or maybe on windows it's different...
Yeps. On Windows it is extremely simple to set fixed clocks, fans, overclocking, so you can easily have a "benchmark platform".
With a headless Linux system I don't think there's any solution for fixed fans yet, others might know differently. I previously had fixed fans and clocks on Linux, but I perfectly recall that I specifically had to configure/attach a monitor in order to get that working at the time.
to set the fan on linux just test this

Thanks, but I fear it needs a monitor or the x session will not start... Or will it?
NOT ANY MORE--
If you have one of the latest driver packages, you can use nvidia-config to enable cards without monitors to be adjusted:
"sudo nvidia-xconfig -a --cool-bits=28 --allow-empty-initial-configuration" (Source: https://bitcointalk.org/index.php?topic=826901.msg12279696#msg12279696)
The numbeer "28" is a bitsum that signifies clocks, fanspeed, and power controls.
This was in this thread, earlier. I think that "-a" and the longer "--allow-empty-initial-configuration" are equivalent.
--scryptr
-a is equivalent to --enable-all-gpus, which configures an X screen on every GPU in the system.
I've tested the sctipt on Ubuntu 14.04 with two 750 Ti.
To set fixed fan speeds
Code:
sudo ./cool_gpu2.sh 72
To reset to default Code:
sudo ./cool_gpu2.sh stop
THANK YOU! --
For correcting me. I should have read the manual first.
