Silent Eagle CPU Cooler: multi-socket heatpipe cooler with preinstalled Silent Eagle 2000 Fan / Frameless fan design

Sharkoon introduces a new CPU-Cooler for AMD (939) and Intel (775) systems. The Sharkoon Silent Eagle CPU Cooler consists of a heatpipe cooling design with a preinstalled Sharkoon Silent Eagle 2000 Fan. The highly awarded Silent Eagle Fan distinguishes itself through the unique, golf ball design of its fan blades. Many small, round dimples on the fan blades reduce wind turbulence and displace high volumes of air with a minimal amount of noise. The heatsink is mounted vertically on the motherboard and three, u-shaped copper heatpipes direct the CPU's heat away from the socket and into the aluminium fins. The heatpipes are mounted through the aluminium base and have direct contact with the CPU. The fan is connected with vibration-free rubber bolts and mounted directly in front of the aluminium fins to provide an optimal air stream across the motherboard.

For quiet operation the fan comes with a frameless design. In order to reduce air resistance, Sharkoon designed the Silent Eagle Fan's plastic frame as a small round bezel with included cable management. The dimensions of the cooler with the installed fan are 77 x 130 x 100 mm. Included in the packaging are mounting pins and a backplate for Intel systems, a retaining clip for AMD systems, a wrench and heat paste...

Come on guys, can we get an engineer in the crowd please? Dimples on the blade surfaces INCREASE turbulence, thus eliminating separation. Separation of the flow would normally cause much noise, reduced flow, and would strain the motor by causing tons of resistance. By adding turbulence, it increases the drag due to turbulent flow, but that is a pittance compared to the drag and noise caused by separation of the flow.

This is a very nice design for a cooler and I am amazed no one ever thought to dimple the fan blades sooner. Good thinking, Sharkoon!
