Help to configure automatic fan speed and cpu frequency on ThinkPad X260

[Joel Carnat]

Hello,

I am discovering DragonflyBSD v5.8.3 on a ThinkPad X260.

I have read and configure the system according to the documentation I 
found on the website and various man pages I read. But the fan keeps 
blowing, even when the system is IDLE. And as far as I can tell, the CPU 
frequency doesn't seem to go to its minimum value ; which probably leads 
to the fan issue.

Here's what I have configured:

$ /boot/loader.conf
acpi_thinkpad_load="YES"
acpi_video_load="YES"
drm_load="YES"

$ /etc/rc.conf
powerd_enable="YES"
#powerd_flags="-u 7 -r 0.2 -T 60"

$ /etc/sysctl.conf
hw.acpi.cpu.cx_lowest=C3
machdep.mwait.CX.idle=AUTODEEP

The CPU is "Intel(R) Core(TM) i5-6300U CPU @ 2.40GHz".

I have attached extracts from sysctl.

I already ran OpenBSD 6.x and FreeBSD 13 on that particular machine and 
when idling, then fan becomes silent. So there must be something I do 
wrong with my dfly configuration.

Any advices?

Thank you,
Joel
