Fan Tray and Speed Variation

Fan speeds are adjusted based on calculations of the temperatures on all sensors. Due to one fan being
located behind the other, air pushed from one fan may cause the other fan in the module to run at a
higher speed. One fan can run at medium speed while the other can spin at high speed if one is close to
the temperature boundary.
