--- Comment #3 from Martin Peres <martin.peres at ensi-bourges.fr> ---
Thanks TM for reporting this bug!

Could you test the following cases, please?

- inverted PWM: The fan may be inverted. 35% would then translate to 65% and
increasing as the temperature falls down. Could you try the manual fan
management and set the pwm to 50%? Please tell us what happens to the fan.

- If the previous test yielded no modification in the fan speed at all, then
either we are driving the wrong PWM controller ... or our settings are not
taken into account. PTHERM may override the fan speed and set it to 100%. Could
you please dump PTHERM's reg space please ? "nvapeek 20000 1000" will do :)
Could you also add "nvapeek e114 20" please?

Looking forward to hearing back from you!
