Computer Power Supply and Switch Wiring Questions

0.4A is higher than I would have expected for a typical fan, but is fine.

What do you mean by "Also, I did a bit of thinking, since the "controller" varies the fan, through voltage *most likely*, on 5V, it'd probably be giving like 3V on full low..
So, on full, it ran, so HAH!"? You have a controller that is running on 5v?

Well, I mean.
The fan is hooked to the controller, which is hooked to power.
I changed the power input to 5V (what I'm gonna end up doing..), so when I turned it to low, I would assume it changes the fan voltage down, while on full, it'll let the 5V (or whatever) go right through...

Also.. if I connect for 7V, and I'm removing the grounding wire..
Shouldn't I be... well, upset after connecting it?

I mean, I have a metal-steel controller mounted on metal-steel chassis...
