Hi there!
related to this part of your faq and to my motherboard Asus A7V266ex, I
want to report a solution for the fan settings in /etc/sensors.conf what
actually didnt work with the default settings.
4.17.1 Bad readings from the AS99127F!
The Asus AS99127F is a modified version of the Winbond W83781D. Asus will
not release a datasheet. The driver was developed by tedious
experimentation. We've done the best we can. If you want to make
adjustments to the readings please edit /etc/sensors.conf. Please don't ask
us to fix the driver. Ask Asus to release a datasheet.
- ----------------------
I tried to find out the correct settings and I've seen that the Asus tool
for watching the sensors is using a switch fan_div 4 and I tried that to
set for the AS99127F settings in /etc/sensors.conf
What shell I say, it works and the fan speed is identic to that what my bios
itself shows up in Hardware monitoring.
Dont wonder about the low speed, its an 80mm fan, the cpu itself is
watercooled.
here is the output:
