Abstract
A system to control the interior temperature and particularly the slider and disk temperature of hard disk drives that utilizes the spindle motor to spin a fanning structure. The fanning structure is preferably integrated into the hard disk drive and initiates a cooling air stream that is directed within the contained interior of the hard disk drive toward a Peltier-element that drains the thermal energy into the surrounding environment. In an alternate embodiment, the fanning structure initiates an exterior air stream that provides a cooling air stream at the outside of the Peltier-element. The Peltier-element is controllable to decouple operational temperature variations from environmental temperature variations.
