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 pinlocations for universal mounting on various board assembly (hole to hole distance 54.6mm and 59mm)
• Formed of pure copperfor enhanced thermal conductivity
• Excellent surface flatness minimizes the interface between the heat source and heat sink
