Since updating to kernel 3.15, the pwm fan speed of my 550 Ti card is too high (above 35% in all situations) when compared with the proprietary NVIDIA driver (that hovers around 30%).
The only way to reduce it to silence once again is to manually change the pwm1_max value under sysfs to 30 (by default it's 100).

Can you tell me the temperature of the GPU (run "sensors"). Then, could you send me your vbios (http://nouveau.freedesktop.org/wiki/DumpingVideoBios/) ?

Thanks for reporting the issue.
