I agree WattMan is "missing" an automatic link between Fan and Temperature control -however- you can finetune it even more PER application. When you set your temps, you can also set your min and target RPM's so in essence it's fully user controlled as opposed to a guessed percentage if that makes sense.
So, set both your targets on Fan and Temperature and play around with your acoustic settings if it gets too loud. Don't mind my readings, I don't have fans on my GPUs. AMD tools have always been (to me) about full user control which doesn't necessarily mean "slide-and-play".
