Solid material. Metal shell + metal base, stable structure, , can not only efficiently dissipate heat, but also protect M2 hard disk High speed 2010 fan. Maximum air volume: 1.35CFM, in order to avoid taking up too much space inside the chassis, M2-TWO uses a 20x20x10mm exquisite fan, the speed is up to 14000RPM, although the size is small, the performance is strong Aluminum alloy heat sink. The heat of the M2 hard disk is conducted to the aluminum alloy heat sink through the thermal grease. The 2010 high-speed fan blows out the heat quickly to that the hard disk works efficiently and with low noise: less than equal 24dBA Grille shape. The heat sink adopts a grille shape, which increases the heat dissipation area and ensures the smooth flow of the air path, which is convenient for the rapid dissipation of heat. Maximum wind pressure: 4.31mmH2O Model: M.2-TWO Cooling method: active cooling Rated voltage: DC12V Rated current: 0.054A Input power: 0.65W Fan speed: 14000RPM Maximum air
