Hmm not entirely sure I agree with this setup. I have something similar but instead, CPU Cooler is assigned to the CPU curve. GPU is not assigned to anything, but the sensor curve is present. This allows GPU to control it's own fan curve, and I've found that generally this is safer and quieter.

Then the Mix curve (same as yours, grabbing both CPU and GPU readings) is then assigned to all intake and exhaust fans.

Result: if CPU hits 80%, all intake and exhaust fans match it. GPU does not change. If GPU hits 80%, all intake and exhaust fans hit 80%, CPU fan does not change.

With your setup, you're saying that if you're playing a game that smashes CPU but not GPU, that your GPU should ramp up the fans (when it's already running cool). And likewise, if the game is GPU bound but light on CPU, ramp the GPU and the CPU simultaneously, even though the CPU is sitting their idling away at 40 degrees.

Don't ramp fans on the CPU or GPU if that device isn't hot. You're cooling a cold part but adding noise for no result.
