The Aerocool Shark Red Edition 140mm x 25mm fans are a great addition to any system. The fan comes with a Voltage reduction cable to allow operation @ 7V without a controller or external device. This allows a range of specs to be achieved with just one fan. The 15 blade design allows for higher air pressure and air flow! All the cables for the Shark Series are factory sleeved in black. Four Red LEDs are built into the frame for added effect.

• Innovative Fluid Dynamic Bearing for longer life span, higher precision rotation, and anti-shock function.
• 15 fan blades generates High Air Pressure and Air Flow.
• Unique and Stylish "Shark Fin" Fan Blade design.
• Duo Mode Operation - The Shark fan operates in both "Power" mode (12V) and "Silence" mode (7V - with adaptation of Voltage Reduction Cable).
• All cables are sleeve wrapped in black.

I purchased three of these for a triple rad setup. The fan blades themselves seem excessively thin. To the point where there flimsiness concerned me. The frame is well constructed and the cabling was sleeved very nicely. After about 4 months two out of three of these started sounding a bit strange. At first it sounded like HDD chatter but I quickly discarded that theory by unplugging these fans. It''s gotten worse and worse over the last two weeks. It seemed that tapping on them would help at times. Probably wouldn''t buy these again unless maybe i just received some bad fans. I''ve always had good luck with aerocool in the past.
