A cabinet (30) having an exhaust fan (F) that creates a primary air flow across heat generating electronic components includes a cooling enclosure (11) which encloses predetermined components (C) to isolate them from other components in the cabinet (30). An air inlet conduit (18) connects the cooling enclosure (11) with the air inlets in the cabinet (30) and an air outlet conduit (19) connects the enclosure (11) with the air outlets of the cabinet (30) and the fan (F) to define a separate secondary air flow across the isolated components (C). The fan (F) creating the primary air flow across the non-isolated components simultaneously creates the secondary air flow across the isolated components (C), where heat generated by the isolated components (C) and non-isolated components is not mixed to maximize cooling of all components within the cabinet (30). The cooling enclosure (11) may also contain a heat sink (H).
