Redundancy and Overkill time, (best reasonably priced thermostatic cooling fan)

You're making this waaaaaay harder than it needs to be.
Like I said, redundancy and overkill is what I Want. The wiring is fat gauge wire, fuse on every electrical item, 20 gauges,4 wheel disc brakes etc etc. This will be my sons car, his sons car and so on. So im beefing everything up so it will rarely be in need
Of repair and everything will last a long time.
