Enermax are using a Globe Fan, model number RL4Z B1352512H. This is a ball bearing fan with a maximum rated rotation speed of 1,500 rpm. We have seen this fan used in other power supplies such as those by OCZ. It is a common choice within Sirtec manufactured supplies. The fan runs for between 30 to 60 seconds after the power supply has been shut down to help dissipate the remaining system heat. This feature is not implemented on the 350W/450W and 550W models.

The power supply incorporates several rows of large heatsinks which will help ensure optimal running temperatures.

All models in the NAXN range are based on an improved 5V standby circuit to reduce the energy loss by about 20 percent and to support ErP Lot 6. We are pleased to see high quality 105c Rubycon capacitors used in the design. The power supply supports multiple protection across OVP, UVP, OPP, SCP and SIP.

The cables are fully sleeved inside the chassis with cable ties, there is also a rubber protective strip across this section to ensure long term safety and protection against fraying.
