I would guess so, Eric. The Aussie chap that has been severely over-running these motors (and who has made some interesting discoveries about ways to improve their performance by changing the magnets) relied solely on air cooling and found that just replacing the standard, very crude, pressed metal fan that holds the sensor magnet array, which is under the non-drive end of the motor, with one machined from an aluminium billet, made a significant difference to motor temperature. He has been running his ME0913 at 700A peak and found that it gives pretty good performance.

Since the temp sensor is at the hottest location that is the toughest to cool, temp drops there actually mean something.
