I disagree but then, I'm not an engineer and was even wrong once (though I might be mistaken about that). The air movement has no additional effect on the coolant over ambient temp. If the solution is gelled, it did so at ambient temp and could indeed block the thermostat from working correctly thereby never getting warmed by the engine except for radiant heat (which itself could be blown away by the wind).
