Described is a fan assembly constructed to enable fans to be installed and removed from a storage enclosure individually or collectively. The fan assembly has a plurality of fan packs and a support frame that includes a plurality of wells for holding fan packs. Each fan pack includes a fan and a fan mount attached to the fan, and each fan pack is disposed in one of the plurality of wells. A first latch-and-release mechanism secures one of the fan packs to the side walls of the well within which that fan pack is disposed. The first latch-and release mechanism enables that fan pack to be removed individually from the fan assembly. A second latch-and release mechanism secures the support frame to opposing side walls of an enclosure. The second latch-and-release mechanism enables the fan assembly to be removed from the enclosure while populated with the plurality of fan packs.
