Cooler Master are making a big song and dance about these fans and on paper they certainly look interesting. The fan in this power supply is called the Mobius 135 with a maximum rotational speed up to 2,400 rpm. It is DC 12V/0.4A. These fans are, unsurprisingly, made in China.
Cooler Master ‘Ring Blade Design (RBD)' diagrams are shown here, from the company themselves (above). They claim the interconnecting fan blades are designed in house and are reinforced for ‘stable and concentrated airflow'. We have seen a lot of fans over the years so it's easy to get bogged down in buzzwords at times. Their life span is rated at 100,000 hours before failure.
This is a power supply that Prince would have been proud to own. The design offers OPP/ OVP / OCP / SCP / UVP and Surge and Inrush protection. This is an interleaved PFC design which helps decrease power loss by minimising the current and reducing interference. Cooler Master are using high quality Japanese capacitors throughout the design to help improve ripple performance and to offer more reliability.
There are several large heatsinks running along the length of the densely populated main PCB to aid with heat dissipation. Soldering quality throughout is very good.
Cooler Master's capacitors of choice in this unit are Toshin Kogyo, otherwise more widely known as TK. The two primary capacitors are 105C rated, 650V 680uF each for a total of 1360uF.
