A heat sink ( 100 ) includes a cooling block ( 105 ) having a plurality of fins ( 110 ) extending through the block to provide a series of coolant channels ( 112 ) extending between the fins, the channels having in the interior of the block a venturi narrowing. Beneficially, the channels have coolant entry regions in at least two different regions ( 115, 120 ) of the block to direct a plurality of coolant flows into the interior of the block from different directions. Also described is a method of cooling a device such as a processor of a mobile computer used in a vehicle by placing the heat sink or more than one of the heat sinks adjacent to the device to be cooled, preferably with a region in which the venturi narrowing of the coolant channels is provided close to the hottest part of the device to be cooled.
