dmesg and vbios tared
My gpu: NVIDIA Corporation GK104 [GeForce GTX 760]
Running kernel 3.14.18 I can't control fanspeed. There are no pwm1 files in
/sys as mentioned in
<a href="https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/tree/Documentation/thermal/nouveau_thermal">https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/tree/Documentation/thermal/nouveau_thermal</a>.
fan1 is always at maximum, while the temp1 is around 37°C.
Running kernel 3.16.2 with the same .config everything runs smooth (fan1 720
RPM, temp1 +39°C).
The most important difference in dmesg is:
3.14.18:
nouveau [ PTHERM][0000:01:00.0] FAN control: none / external
3.16.2:
nouveau [ PTHERM][0000:01:00.0] FAN control: PWM
dmesg | grep nouveau attached
Thanks in advance</pre>
