With rising processor power dissipation and the decreasing allowable maximum processor case temperature, immediate cooling design improvements are critical for system survival. The "Processor Heatink with Slotted Fins" is designed to incorporate significant improvements in todays cooling capabilities with little design changes. The "Processor Heatink with Slotted Fins" invention has 6 advantages over a comparable heatsink without slotted fins: 1) Increased Surface Area More area for heat spreading than with a heatsink of same design without slotted fins (taking away 0.3mm of material while exposing 0.4mm of material in cross section). 2) Reduced Impedance Allows greater volumetric airflow.
