I don't know what parameters to pass to i2detect and i2cdump. I've tried some
adresses like 002e and lots of others but i don't know which one. I'll take
time to read man for i2cdetect and i2c dump. But i don't have time to do it
OK i realised that /sys/bus/i2c/devices/0-002e/name contains adm1027 instead
of adt7463. Actually, i don't know which one is right since i can't read the
name of a chip that is "jailed" in a laptop.
Do i have to load the lm85 module with special options like :
modprobe lm85 force_adt7463=xxxx
What should i put instead of this xxxx ? modinfo lm85 says "list of adapter,
address pairs, what does it mean ?

Well, i thought that the fastest the fan turns, the more energy is spent and
the shorter the battery lasts. No ? If the fan does not spend a lot of
energy, reducing fan speed has at least one advantage : less noise !

Should i use something like :
set pwm1_zone 123
in /etc/sensors.conf in the appropriate section (lm85 and co...), as explained
at the end of your linked document ?
Any way, thanks a lot !!!
