Copy-n-paste typo for this last value?

Yep everyone seems to agree - I've updated my patch:
http://jdelvare.pck.nerim.net/sensors/hwmon-it8716f-it8718f-v3-2.6.18.patch
Fan readings for fan1 and fan2 should be OK now - not sure about fan3.
Can you test and report?

Yes, your CPU can change its Vcore depending on frequency.

> 3,3V		3,41V		3,22V (i think it is the voltage called VDDR)

Then just change the label to "+3.3V" in sensors.conf.

Hmm, all your voltages are lower in sensors than in the BIOS. We just
had a similar report, however I also had reports where the voltages
match so I think the driver works. I just can't explain this difference
on some Asus boards.

For temperatures it is OK, BIOS is usually in a busy loop so slightly
hotter than Linux at idle.

Ah, hardware is too recent for lm_sensors 2.10.0's sensors-detect. Can
you please pick SVN's version and try again?
