A cooling system is configured to supply individually metered amounts of cooling
fluid to heat generating components of an electronic system. The cooling system
includes at least one variable speed fan configured to supply fluid through a centralized
plenum and thereafter through a plurality of nozzles to the components of the electronic
system. Each of the nozzles contains a valve to control the amount of fluid flow
through the each of the nozzles. A controller is provided to control the operation
of the variable speed fan and the operation of each of the valves is also controlled
by a controller.
