conditions (55°C and 6000 ft altitude)
Air temperature rise is 68°F (20°C) on a fully
loaded system with fans running at
maximum speed.
Note
Air exhaust temperature
500 ft/min (2.55m/s) under typical conditions 27°C
1000 ft/min (5.1m/s) at maximum speed
Software controls the speed of the fans based
on measurements from the chassis thermal
sensors.
