Yoga S740(710) Shows Current Speed but doesnt set target speed

[MarioGK]

Hi i am using the Yoga S710 config, it seems to be reading the value correctly of the current speed, but the target speed is always 0 and it is not overriding/controlling the speed, is there any way i can debug this?

Read-only               : False
Selected config name    : Lenovo Yoga 710
Temperature             : 34.8

Fan display name        : Fan
Auto control enabled    : True
Critical mode enabled   : False
Current fan speed       : 64.41
Target fan speed        : 0.0
Fan speed steps         : 0

The syntax is a bit confusing, did you try this: sudo nbfc set -f 0 -s 100 This should set target fan speed to 100 percent

Are you sure it's never calling? I was just about to update issue #10 with observing similar behavior, but my issue could differ from yours in two ways (difficult to tell as you haven't given many details):

• I definitely have instances where the target (and actual speed) is non-zero, so nbfc is scaling according to temp
• my fans currently aren't moving, despite saying the current speed is >0 (the error is the current, not the target reading)

Also, can you post the output of ec_probe dump and nbfc status -a , as well as link to the actual config. I don't know Lenovo models and there's an Ideapad 710S as well as a Yoga 710 and Yoga 710 KabyLake.
