Thomas-
As stated in a thread earlier this year - it has something to do with the
velocity being too high to actually transfer the heat from the radiator -
much like the alternate problem with running without a thermostat allows too
much water flow through the radiator.

Possibly the non-moving fan is obstructing airflow across the radiator???
