High efficiency jet flow generator for storage cooling

A method, comprising:

• providing a computer chassis having:
• one or more chassis walls defining an airspace having an air inlet and an air outlet;
• a printed circuit board (PCB) layer positioned within the airspace to split the airspace into a first region and a second region, the PCB layer having a plurality of connectors for receiving a plurality of heat-generating components in the first region, the PCB layer having a forward end adjacent the air inlet and a rearward end adjacent the air outlet, the PCB layer having at least one air opening positioned between the forward end and the rearward end to permit passage of air between the second region and the first region;
• and
• at least one baffle positioned in the second region adjacent the at least one air opening;
• receiving air into the first region and the second region via the air inlet, wherein air received into the first region via the air inlet is first input air and air received into the second region via the air inlet is second input air;
• passing the first input air past at least a first portion of the plurality of heat-generating components to heat the first input air;
• passing the second input air into the first region via the at least one air opening, wherein passing the second input air into the first region via the at least one air opening results in passing the second input air past at least a second portion of the plurality of heat-generating components to heat up the second input air.
