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).
