I'm guessing that the design is still a hydraulic-based system - is it not? I know my 2000 LS V6 has the hydraulic fan system which allows the fan speed to be variable and even on HOT, HOT 90+ degree days with the A/C running - my fan is rarely audible - whatsoever.
I have heard it run on full speed once and that was in a local car garage while hooked onto a tester and it ran through a series of tests and one was to kick the fan into high.
Not sure what would cause yours to kick onto high, but if the temp gauge is reading the usual 1/2 way - something is definitely amiss. Like some electrical code is telling the fan to go on high. Are you getting the engine light?
Has there been any work done on the engine or reason for the coolant to have been emptied or changed - not sure - but if there was an air bubble in the cooling system - maybe that would cause something to trigger? I don't know for sure - just offering up info about info on the hydraulic and that it never goes on what seems like medium for mine.

that having the cooling system bled properly (to eliminate ALL air pockets) is essential & will eliminate two problems: 1) cooling fan running at full speed & 2) poor heater performance. I found a dealer that knew how to do the bleeding procedure correctly & both problems went away for me.- « Previous
