Questions about this item

Will the fan need bearing lubrication or full replacement after a year of daily use?

The fan is tested individually before shipping and covered by a 9-month warranty; bearing wear beyond that period would require a new unit.

What thermal limit triggers throttling on the Lenovo M4400s or M4450s when the fan runs continuously?

The CPU in those models reduces clocks once its internal thermal threshold is reached; the fan maintains airflow at 5 V and 0.5 A to delay that point.

How much noise and heat does the 5 V 0.5 A fan produce during all-day operation?

At its rated 5 V 0.5 A the fan spins quietly enough for office use and adds only a few watts of heat to the chassis.
