Jitter Control and Operating Profiles for Air Moving Devices

An electronic system comprising:

• an air moving device;
• and
• a controller for controlling the air moving device, the controller configured to selectively control a rotational speed of the air moving device, the controller configured to vary the rotational speed within a range bounded by and including a first rotational speed and a second rotational speed during a time that a target rotational speed is within the range.

A method of controlling an air moving device in an electronic system comprising varying a rotational speed of the air moving device within a range of rotational speeds that includes an intended rotational speed.

51-73. (canceled)

An electronic system including:

• a plurality of air moving devices;
• a controller configured to control the plurality of air moving devices;
• a user interface to allow a user to select an operating profile from a plurality of operating profiles for the plurality of air moving devices, the plurality of operating profiles including at least two of a high efficiency profile, a low acoustic noise profile, a high cooling profile and a long life profile.
