Designed by researcher Jeffrey Koplow, the Sandia Cooler does away with a separate fan component, and instead relies on the heat sink itself to disperse heated air.
Traditional CPU heat sink designs usually feature a metal heat sink and a fan working in concert to siphon off the heat generated by computer parts. However, that design creates a 'boundary layer' of air, retaining the heat that the fan is
supposed to disperse. The power necessary to drive the fan, as well as the fan's proximity to the boundary layer, makes that design inefficient. The Sandia Cooler eliminates the fan, replacing it with a finned heat sink that can disperse the boundary layer far more efficiently since the two are in closer contact.
