GPU and CPU Mixed Fan Curve

[wsm78]

I have an RTX 4090 MSI Suprim Liquid and was wanting to use its default fan curve settings for its radiator. I want to make a mixed fan curve specifically for switching between my custom CPU coolant curve and the default GPU fan curve. Is this at all possible does anyone know?

Keep the GPU controls disabled.
Create a "sync" fan curve. Select your GPU as its source.
Create a mix, mix your sync and your CPU coolant curve.

So I'm assuming there isn't a way the other way around then? If the CPU kicks up but the GPU does not?

The previously stated setup would kick up either if the gpu or CPU heats up.

Experiment with it, you'll see for yourself how it works out!
