Enzotech’s CNB series is the world’s first complete one-piece forged copper Northbridge heatsink with no interface or gaps. It gives you the best thermal performance possible without using a fan. The chipset is cooled to optimum operating temperature with no fan noise or vibration. CNB-S1L can also be used for some Southbridge or VGA applications.
Multiple push pin locations for universal mounting on various board assembly (hole to hole distance: 53mm to 59mm)Formed of pure copper to enhance thermal conductivity.Excellent surface flatness minimizes the interface between heat source and heat sink.Dimension36 x 36 x11.6(H) mmWeight50gMaterialForged copper 1100Base FlatnessPolished mirror surface, flatness for machined surfaces are typically in the range of 0.0003" to 0.0004"per inch
