Lock fans to multiple sensor profiles based on temp, load or even voltage.
This is basically an expansion on the select cpu sensor idea.
Even though I use multiple platforms the idea of being able to lock fans to different sensors is one I am very keen on.
My AM3+ gaming machine has all fans bar the CPU fan set to the GPU since that kicks out more hot air than the CPU ever will.
But with different sensor options I could stick a grid+ v2 into my AM4 audio workstation to control airflow all over the case based on M.2 temps, ambient, cpu, harddrive or even voltage going into my soundcards...that would be freaking ace.
