A cooling device for an electronic component, such as a computer processor, generally comprises a heat sink and a pair of fans. The fans are redundant in that sufficient cooling is supplied should one fan fail. The fans are independently powered and are inspectable and independently replaceable in situ without un-powering the other fan or the processor. The heat sink includes a base plate having a bottom for surface contact with the processor, a front row of fins projecting upward from the front of the base plate and a rear row of fins projecting upward from the rear of the base plate. Right and left fans are mounted substantially within a cavity between fan rows. Each fan blows a flow of air such that the flow impinges on the base plate. A central channel between the front and rear fin rows provides a path for air impinging on the left side of the heat sink to flow to the right side, should the right fan fail, and for air impinging on the right side of the heat sink to flow to the left side, should the left fan fail.
