DeepCool have opted for a Hong Hua HA13525H12SF-Z Fluid Dynamic bearing fan. This fan is rated 12V, 0.5A and should last many years.
This is a CWT OEM design which has been adopted in several power supplies lately. It is a solid design. A half bridge topology and an LLC resonant converter feature on the primary side. It is reassuring to see two high grade 105c rated Japanese Nichicon capacitors on the primary side rated 470uf, 420V, for a total of 940uF. Two VRM's are used to generate the minor rails. Soldering quality on the PCB is high with some copper plates used.
