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-S1 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.
