Summary0002154: MAX of speed problem
DescriptionI select multiple temperatures to control a fan, method is "max of speed"

I observe that the effective fan speed is not the maximum of the speed of each of the response graphs, but usually (under load) much higher. I could not find a mathematical correlation of the observed speed and the settings of the response graphs.
Steps To ReproduceSet fan control with curve for GPU temperature. Fan speed has to increase after GPU temp of 82 C or higher. It works fine.

Add temperature control on same fan based on CPU temperature, method is "max of speed". Fan speed has to increase at CPU temp of 60 C or higher.

Observation : after starting a game, CPU and GPU temp start increasing.
Even when measured temperatures stay below both CPU and GPU thresholds, fan speed still increases to near maximum speed.

Please close the report as solved. The temperature warning was set too low and caused the observed behavior.
