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.
This is the first fan from Cooler Master to adopt Barometric Ball Bearing (BBB) technology.
Barometric Ball Bearing (BBB) Technology The innovative Barometric Ball Bearing technology provides longer life span while remaining lower noise level.
Removable Sword-Shaped Blades with Triangular Blade Tips The Cooler Master Excalibur R4-EXBB-20PK-R0 is equipped with nine massive sword-shaped blades which generate outstanding high air pressure with balanced airflow for exceptionally cooling efficiency. Triangular blade tips reduce turbulence at fan edges and decrease wind shear noise while keeping maximum sweeping area. The blades are removable for quick and easy cleaning.
Honeycomb Ventilation Meshed Frame The honeycomb ventilation meshed frame works as a secondary intake to increase airflow under low fan speed operation, or helps reduce noise by releasing excessive turbulence and vibration when the fan spins at high speed.
Sturdy Structure The Cooler Master Excalibur R4-EXBB-20PK-R0 features 3-piece frame with metal rim for robust structure.
PWM Function The PWM function automatically adjusts fan speeds according to the CPU temperature for efficient cooling and minimized fan noise, a total performance solution at high and low speed operation.
