Cooler Master Excalibur fan uses barometric ball bearing

Posted on Thursday, January 28 2010 @ 12:12:58 CET by

Cooler Master shows off the Excalibur, a new 120mm fan with Barometric Ball Bearing (BBB) technology to generate superior air pressure with balanced airflow. The fan has removable fan blades and uses a honeycomb ventilation meshed frame. It delivers an airflow of 26.4CFM to 85.6CFM, with an air pressure of 0.75 - 3.53 mmH2O at a noise level of 13dBA to 30dBA.
Barometric Ball Bearing (BBB) Technology
Barometric Ball Bearing is a uniquely advanced technology to maintain barometric pressure in the center of the fan. The benefits of BBB fans are longer life expectancy than traditional bearing fans, lower noise level and higher reliability. The blades can be easily removed for quick and easy cleaning.

Sword-like Fan Blades
Excalibur, as the name suggests, is inspired by the legendary sword of King Arthur from the middle ages. The nine massive sword-shaped blades are designed to produce exceptionally high air pressure, which fortify the cooling efficiency when used in dense water cooling radiators or performance heatsinks. Its triangular blade tips reduce turbulence at fan edges and decrease wind shear noise while keeping maximum surface area.

Robust Frame and Honeycomb Ventilation Mesh
The unique 3-piece frame with metal rim of the Excalibur provides a durable structure with a functional purpose. The honeycomb ventilation holes on the frame works as a secondary intake to increase airflow under low speed operation. At high speeds these ventilation holes help to reduce noise by releasing excessive turbulence and vibration. The metal frame adds a performance outlook while improving airflow and reducing blade noise.
