Here, CPUTIN and AUXTIN (whatever it is) are obviously wrong. CPUTIN
*decreases* towards 17°C when the CPU gets hot (non-linearly, though).
Odd. No idea what is going on, though. The registers are quite straightforward,
and the same for NCT6775F and NCT6776F. And it works on my system with NCT6775F.
Is there the option that auto-detection was wrong and I have a
completely different chip?
This was the first problem. The second problem occurs when I try to
control fan2 manually. The "pwm2" file in sysfs is 255 for anything
above 2000 RPM, but as you can see above, the fan can do more (I've been
at 2600 RPM -- maybe it can do even more), but pwm2 stays at 255.
Looking through the datasheet, I did not find anything obvious. It might
be possible that the PWM output frequency (register 2 bank 0) somehow affects
the fan speed as well. What causes the fan speed to go higher in your system ?
High temperature in Temperature Cruise mode.
My firmware setup interface actually provides me with both the options
"Target fan speed" and "Target temperature", but I have the impression
that while the driver reports that I'm in Temperature Cruise mode, the
fan speed does not vary that much, but it rather tries to keep the fan
speed constant unless temperature is completely out of range.
The fan speeds up only when I'm above 60°C, and even that with a certain
delay, so under full load, I get above 70°C when my fans are
firmware-controlled... That's basically the reason why I want software
control.
