[lm-sensors] Quick question Winbord w83627ehf - BIOS vs manual

[Mihai Tanasescu]

Hello guys,


I'm having some "theoretical" dilemmas here and wanted some help if 
possible.

I'm having an Asus P5B Deluxe MB with a W83627DHG chip.

Prob:

If I enable in Bios, Q-Fan Control (Thermal Cruise in normal language:) 
), then do the settings in /sys like:

/sys/devices/platform/w83627ehf.656/pwm1_enable
pw2_enable
etc
pwm1_target
pwm1_tolerance

get set automatically based on what is read by the BIOS ? or do I have 
to set them ?

Also, if I set them, do they overwrite the BIOS settings ?

I'm a bit confused here and would be grateful if you could shed some 
light on the subject.



Thanks,
Mihai

I partially found the answer to this...

The settings are read from BIOS.

Half the question still remains...if I change anything manually there 
with echo "value" > /sys/... then does it take effect and override the 
BIOS setting ?

Why not try it and monitor the outcome?

Sadly I did..but can't see any change in the fan speeds.

I retried right now..without any result.
