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.
