I too am curious why your fan runs all the time, I live at 2,590m elevation on very steep switchback mountain roads with ambient temperatures around 27+C in the summer and have no heating issues the fan only comes on when stopping or stopped, I also have an override switch with a timer so I can run the fan after turning the engine off. Even going up Pikes Peak at 4302m did not cause the fan to come on whilst moving, often drive well over 3,300m on hot days (we are classified as high mountain desert) and have never experienced what you describe.
P.S. I have a thermostat controlled oil cooler but the engine has to get really hot (which it needs to) to activate.
