A noise suppressing heat exchanger (also referred to as heat sink) includes a plurality of heat dissipating fins formed with baffles. The baffles suppress noise from a fan by slowing air flow and creating internal reflections within the heat exchanger that reflect noise away from the air flow path, absorbing sound energy and potentially setting up standing waves which dissipate noise via destructive interference. Other embodiments may be described and/or claimed.
