Question about thermal mode of WolfPass
Closed this issue · 2 comments
Hi,
I am looking into fan-control feature of WolfPass these days,
and I got some question about thermal mode setting.
As far as I know, there are two thermal mode settings:
-
"Performance":
Takes input sensor controller "Front_Panel_LCC", "CPU1" and "CPU2" only,
so phosphor-pid-control will not control fan speed in this thermal setting.
(Fan speed will be set in a fix value by set_fan_speeds.py)
Shouldn't the fan speed be adjusted according to the HOST CPU temperature? -
"Acoustic":
Takes all sensor controller on dbus, phosphor-pid-control will control
fan speed according to HOST CPU temperature.
May I know purpose of each "Performance" and "Acoustic" thermal mode settings?
Best regards,

These are still under development, and the clamps for each are changing. The purpose of thermal modes are to create a preference for CPU throttling. In performance, acoustic performance is sacrificed for better CPU performance. In acoustic, CPU throttling may happen to not go over an acoustic fan noise limit.
Hello, James
Thanks for the response.
I got it now.
