CoolerMaster 120mm Excalibur PWM Fan

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. Capable of moving up to 85.6CFM and operating as low as 13dBA. This is the first fan from Cooler Master to adopt Barometric Ball Bearing (BBB) technology.

•The innovative Barometric Ball Bearing technology provides longer life span while remaining lower noise level.
•Removable blades for quick and easy cleaning.
•Nine massive sword-shaped blades generate outstanding high air pressure with balanced airflow.
•Triangular blade tips reduce turbulence at fan edges and decrease wind shear noise while keeping maximum sweeping area.
•3-piece frame with metal rim provides robust structure.
•Honeycomb ventilation meshed frame:
- Low speed operation works as a secondary intake to increase airflow.
- High speed operation helps to reduce noise by releasing excessive turbulence and vibration.
•PWM function for total performance solution at high and low speed operation.

Lanoc Reviews
The shape of the fan blades are definitely unique as well. Aside from looking very kick-ass, the sword-shaped design generates even more air pressure and thus better cooling... Read more...
