Abstract
A removably mounted fan for an active heat sink, and the mounting of that combination to a part to be cooled, is obtained by: (1) The use a fan that engages and registers itself upon and against a top peripheral surface surrounding a cavity where the fan is to be located; (2) Holding the fan in place with one or more resilient mounting clips that span the distance from the top of the fan and an opposing outside bottom surface of the active heat sink; and, (3) Providing the resilient mounting clips with outward projecting mounting tabs that are flexible and resilient and that have mounting holes through which the resilient mounting clips (and the active heat sink they grip) can be attached to an assembly carrying the part to be cooled, such that the bottom of the active heat sink is in good thermal contact with that part.
