So Rudolf, this just takes the control loop out of the picture and always
enables the fan? This stuff always confuses me.
Yes it should. I used the same programming as in orig BIOS but perhaps I missed 
something. I will check later what went wrong. The change should make it manual 
mode (which has some non-zero pwm by default, so fan should spin)
Thanks

Hi

I think this is the problem: change the following line in the devicetree.cb

register hwm_fan2_ctl_pwm = "0x80"

To 0x00 For some reason automatic settings for fan2 does not work... or is
badly set up.

Idwer: He uses the extra fan, not only the CPU fan.

Please let us know if this helps,

Thanks
Rudolf
