The unbreakable rule has now been broken. Cooler Master’s Turbine Master is the company’s latest 120mm high air flow fan that refutes the standard of “high air flow fan = loud”. Modeled after a strong turbine engine, the Turbine Master produces a strong air flow from an ingenious 16-blade design & generates unsurpassed airflow combined with a circular semi-frameless design to maximize coverage & reduce noise. The Barometric Ball Bearing (BBB) can be easily removed to provide effortless cleaning & quick maintenance. Low R.P.M., High Air Flow Encompassing power & speed to smoothness & efficiency, the Turbine Master is available in three speeds to suit every need. A choice among 800 R.P.M, 1200 R.P.M, & 1800 R.P.M fans are available, each embodying an extreme high air flow. With air flow as high as 80.3 CFM & sound levels as quiet as 13.83 decibels, this fan will satisfy the needs of silent & even performance systems. Barometric Ball Bearing (BBB) Technology Barometric Ball Bearing is a uniquely advanced technology to maintain barometric pressure in the center of the fan. Progressive barometric ball bearing technology extends the life expectancy of the Turbine Master up to 100, 000 hours of use, while keeping the noise level to a soft, unobtrusive undertone. Features The innovative Barometric Ball Bearing technology provides longer life span while remaining lower noise level Removable blades for quick & easy cleaning Outstanding 16-blade design covers maximum area to generate striking airflow, even under low speed operation High airflow design gives excellent chassis ventilation One-of-a-kind turbine shape inspired by a powerful turbine engine Specifications Dimension 120 x 120 x 25 mm / 120 x 120 x 39 mm (with hub cover) Speed (R.P.M.) 800 R.P.M. +/- 10% Air Flow (CFM) 35.07 CFM +/- 10% Air pressure (mm H2O) 0.42 mm H2O Noise 13.83 d BA Bearing Type Barometric Ball Bearing Fan Life Expectancy 100, 000 hours Voltage 12 V DC Current (Ampere) 0.08A (0.2A MAX) Power consumption 0.96W (2.4W MAX) Weight 123.7 g Connector 3-pin Accessory 4x Rubber screw 4x Metal screw 4x Rubber pad 1 x Molex-to 3 Pin adapter
