Your own experience says that fancontrol, lmsensors and a BMC do not
have a way to coordinate actions which leads to errors and faults.
And as Jean has said, the Winbond chip has a paged register set that
requires coordination to access. The BMC code has now way to
coordinate access with the OS.
Jean mentions thermal trip points. I believe that the winbond chip
includes it's own autonomous fan speed control seperate from the BMC
monitoring. What if you just reprogram the fan control curves in the
Winbond chip once at boot if you don't like the ES BIOS fan control
curve?
Otherwise, no I don't think what you want is possible.
How hot were the CPU under full load with the ES fan curve that you
felt they needed to be colder?

Use ipmitool and perhaps bmcsensors module to monitor sensors.
Go into the bios and under hardware monitoring arrow down to see
fan speeds and then select the ES fan profile (lowest) rather than
Off, performance, balanced. That should make the fan speeds much
slower and quieter
These are the steps that I already took. But I would like to use
fancontrol because then I can make it really quiet most of the time,
yet keep the server relatively cool when under high load. Are you
saying that it is not possible to use fancontrol in combination with
my motherboard?
