Lots of good explainations attempting to help, but I'm afraid it's all a waste of time. We can supply the illiterate with all kinds of knowledge but we can't force them to learn. Some are like a sponge, even a natural grown one has extremely limited brain power.
Without a doubt, the best fan controllers are aquaero. Aquaero 5, aquaero 6 (lite because it does everything other models do without 5.25" mount & front panel) and QUADRO. They have so many possible functions and features with add-ons. They best way to use them is with aquasuite using mouse, keyboard and monitor.
But they have exposed components on at least one side, so if some numb-skull drops conductive items on them while they are running they can short out, just like motherboards, RAM, GPUs, one side of SSDs & HDDs, and more.
There are thousands of computer techs working on Earth working with exposed components every day and rarely if ever shorting them out. Of course they use common sense and don't work on them while running .. and close up cases / cabinets after working on components.
