OK, my bad, I was looking under /proc instead. Yes, there are there.

I used to run this to lower the speeds of the fans and I guess the format is
now different.
echo "0.2 32.0 98.0 1.0 .0.0" > /proc/sys/dev/sensors/`/bin/ls -
1 /proc/sys/dev/sensors | grep -v eeprom | grep -v chips | tail -1 `/pwm2_cfg
Under the new location, the file I think is related is fanX_pwm. When I do a:
cat fan1_pwm
64
and I tried with echo "32" > fan1_pwm but it does not change the value even
logged in as root.
When I try pwmconfig I get.

I don't remember where I got that value. I think what I did was to compare
the values I got back from sensors and tried to compared with what the BIOS
shows for the voltages so this may be completly off. I need to recheck my
stuff later today.
Thanks again.
