Excalibur R4-EXBB-20PK-RO Cooling Fan, 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. Excalibur R4-EXBB-20PK-RO Cooling Fan is the first fan from Cooler Master to adopt Barometric Ball Bearing (BBB) technology.
