Hi.
I bought a motherboard, which has an IT8721F on it, and as asked on the wiki I
report about it :) .
$ sensors
k10temp-pci-00c3
Adapter: PCI adapter
temp1: +29.4°C (high = +70.0°C)
(crit = +70.0°C, hyst = +65.0°C)
it8721-isa-0290
Adapter: ISA adapter
in0: +2.92 V (min = +1.82 V, max = +0.17 V) ALARM
in1: +2.89 V (min = +2.34 V, max = +2.06 V) ALARM
in2: +1.14 V (min = +2.10 V, max = +2.68 V) ALARM
+3.3V: +3.29 V (min = +2.38 V, max = +2.90 V) ALARM
in4: +1.70 V (min = +2.82 V, max = +1.31 V) ALARM
in5: +2.63 V (min = +2.10 V, max = +1.40 V) ALARM
in6: +1.01 V (min = +1.99 V, max = +1.25 V) ALARM
3VSB: +4.27 V (min = +1.30 V, max = +2.76 V) ALARM
Vbat: +3.34 V
fan1: 2657 RPM (min = 14 RPM)
fan2: 1344 RPM (min = 24 RPM)
fan3: 1658 RPM (min = 21 RPM)
temp1: +38.0°C (low = -6.0°C, high = +82.0°C) sensor = thermistor
temp2: +36.0°C (low = +126.0°C, high = +117.0°C) sensor = thermistor
temp3: -128.0°C (low = +17.0°C, high = -15.0°C) sensor = disabled
Voltage:
- obviously lacks scaling/offseting (indeed, it's not configured)
- alarm levels are funny (max < min for most)
- 3VSB is not 3V (scaling again ?)
Fan speed:
- seems correct, although I cannot easily check
- alarm level lacks scaling (non-configuration again ?)
- cannot be seen here, but pwm control works only for fan2 (chassis fan), both
in automatic and manual modes. Other fans (cpu & "power" fan, actually used
for chassis front fan) are at full speed constantly. Setting values and
reading them back returns what was set.
Temperature:
- Unsure about correctness at the moment: temp1 38° idle, 59° full load with
fan at constant full speed seems a bit too narrow (min to high, max too low,
not consistent with k10temp)...
Then again, I'm not used to that CPU yet (Phenom II 1100T), and I cannot
check actual temperature.
No idea for temp2 (motherboard): 36° idle, 38° on load (then again, it does
little as I don't use its integrated gpu).
- Low/high values are funny (non-configuration obviously, but I'm curious
where those values come from...)

I should certainly also report kernel version: 2.6.39-2-amd64 kernel (debian
sid).

Again, with atk0110 loaded (after I noticed the warning in dmesg about using
acpi_enforce_resources kernel parameter preventing atk module from loading).
All values provided again for comparison.

atk driver provides values very close to bios, with following exceptions:
- cpu temp is lower (46° in bios), in my understanding cpu is at full
speed during bios so it can explain
- chassis fan lower (1717 RPM in bios), most probably related to higher cpu
temperature, as its speed under OS follows CPU temperature
- power fan min RPM cannot be set in the bios, others are consistent with my
settings
- MB temperature shutdown level in bios is 95°. Not sure if it contradicts
"crit" level reported above (maybe unrelated).
For some reason, when changing fan settings in bios, linux fails booting after
detecting all hard disks, undoing the config doesn't always cure startup. I
could originally boot in "auto" mode, now I can bot in "manual" mode (bios
controls fans, but I get to set the levels - for no audible difference
anyway). I suspect bios has a good share of bugs (it seems this motherboard is
more recent than I thought... dmidecode says "Release Date: 04/18/2011" in
"BIOS Information" section).

Your copy-and-paste method added a lot of trailing white space, making
your post needlessly large and quoting difficult. Please clean up your
post before sending next time.

This is indeed the driver you want to use on every recent Asus desktop
board.

It no longer matters, but the first 5 voltage labels are wrong. Not
sure where you got them from. in2 is obviously Vcore and in3 matches
+3.3V.

Not surprising, given that the asus_atk0110 driver gets the values from
the BIOS itself, rather than from the monitoring chip directly.

Both correct.

Looks wrong indeed, as it is set to 75°C, not 95°C. Is there a CPU
temperature shutdown level that you can set as well? If so, to what
value did you set it?
What surprises me the most is that the it87 driver reported completely
different limits, which means that these are software limits... The
BIOS never wrote them to the chip (unless you screwed them up yourself
with a libsensors configuration file?) I wonder how such software
limits can be enforced. Maybe this only works on Windows with Asus
proprietary software loaded. Or maybe the BIOS is polling the device
periodically at run-time. Ugly in both cases.

Could be indeed. Feel free to report to the board vendor.

Means that the BIOS is recent, not necessarily the board. But looking
at the Asus website, the board indeed seems to be brand new, so
hopefully any BIOS bug reported now will get fixed in the next BIOS
update.

Sure. Sorry for not noticing.

it87 driver has the advantage of exposing pwm controls in sysfs.

I noticed this too. Maybe this comes from a config I was trying to write for
this chip - I thought I moved it away & reconfigured sensors before posting.

Actually, the "NorthBridge overheat protection" option is a simple
neable/disable switch on a different screen than sensors output & fan
settings.
I could not find any way to configure any temperature limit on CPU.

I don't think so: I could not find any settings for it8721 in either
/etc/sensors3.conf nor /etc/sensors.d/* . All I configured on this chip were
names & fan speed limit, and fan limits were not applied anymore in dumps I
pasted.

No idea. So far, this motherboard didn't see windows.
