The ultra bright fan, from the inside. Notice the unit hasn't been totally sprayed inside.
The Twister fan, uses patented ‘twister bearing technology' which keeps noise levels to a minimum (more on that later), and it also helps to increase the life span with Enermax rating it at 100,000 hours. Most fans are rated between 30,000 and 50,000 hours. The Rotor has an integrated magnet which ensures a frictionless and smooth motion. The bearing sleeve is self lubricating with abrasion protection. The fan also spins for 30-60 seconds after the unit has been shut down to help remove excess heat from the system – Enermax call this ‘HeatGuard'.
The insides are rather unusual, we are not sure if we have seen a PSU with heatsinks all coloured blue. Its certainly eye catching!
AC Filtering starts from this area and the vertical board in the image above is home to four Y capacitors, one X capacitor and a coil.
Two VRMs which handle the 5V and 3.3 V rails.
Enermax have implemented the ‘Dynamic Resonant Transformer Array”. This is based on the highly efficient resonant topology which has been used in LCD monitors. On this PCB there is an additional resonant choke. By using this design zero voltage switching of the main switches is achieved which results in dramatically lower switching loss with boosted efficiency throughout.
We have seen the controllers before on the Seasonic X series supplies. They are the CM6901 and a CM6502 for the PFC section. You can also see the primary capacitor above, a high quality Rubycon.
The electrolytics are Nippon Chemi-Con and the polymers are Enesol branded. VRM's are handled by the APW7073A control processor.
The sleeving is excellent, going into the unit which helps stop any damage to the cabling against the grommet.
