You guys do realise you are talking about two different "fans" - the 2 x cooling / AC fans mounted at the front of the car, and the engine compartment cooling fan mounted just inboard of the R/H side air vent.
The OP first asked about controlling the engine compartment fan, which in my experience only operates for a few minutes in heavy traffic then quickly stops when you get underway and get air circulating around the engine. Its only a small fan with a +/- 100mm blades which really can't do much (apart from making a loud noise) to cool the compartment in stop go traffic or get rid of heat soak after the engine has been restarted after long periods in traffic.
