Abstract
The fan has an arrangement for monitoring the ageing of at least one of its bearing, the arrangement including a reference ambient temperature sensor and a processing circuit for comparing the temperature difference between the temperature measured by the temperature sensor or by each temperature sensor fitted directly on the corresponding bearing and the temperature measured by the reference temperature sensor with a first predetermined value.
