No more mess inside your case.

Durable LDB Bearing

Cooler Master 120mm Silencio FP fan combines sealed LDB bearings with quiet fan blades, offering a long lifetime of quiet cooling.

  • A: The groove outside of the bearing helps to circulate the oil
  • B: Sealant on the bobbin ensures the highest level of dustproof - IP6X
  • C: Recycle slot adds extra storage space for the oil
  • D: The shaft makes the oil flow by pumping it while spinning

MasterWatt Operates at 0dB under 15% load. Experience noise-free basic computing.

Dual Forward and DC-to-DC Circuit Design

The Dual Forward and DC-to-DC circuit design offers reliability and stability. This is especially significant in +3.3V and +5V outputs.

More Conductive PCI-e Cables
