Now that I think of it that fan should have a clutch on it. If it is from a recent car it will have a thermostatic clutch which means it will only come when the preset temp is reached. Also I think there is relay involved in the normal wiring of those fans. I don't know how these issues will affect the situation and I am not trying to talk you out of it, quite the contrary, but they are questions you want to answer before going forward.
