The chip has three pwm outputs, so if you have more than three fans I guess
that one pwm output could affect more than one fan.

How many fan counters (fanX_input) do you see on your system ?

I am a bit confused about the correlation of pwm to inputs and fan behavior.
Are you saying that pwm1 affects three of the four fans ? That would be a bit odd.
What are the values repoted by pwm2 and pwm3, and do you see anything change 
if you modify those values ?

Would it be possible to run pwmconfig and let us know what it reports ?

Thanks,
Guenter
