EK-Quantum Phase 120 D-RGB - Black is EK's most refined 120mm radiator fan engineered specifically for high-performance liquid-cooling systems. Developed through close collaboration with industry-leading fan engineers, injection-moulding specialists, and EK's liquid-cooling experts, Phase represents EK's most advanced fan design to date. EK-OmniLink EK-OmniLink - allows daisy chaining of multiple fans, thus reducing cable clutter and greatly easing cable management. The Omni-Link ecosystem of interconnects will be greatly expanded in the near future, allowing additional benefits to users. It uses Micro-fit 8-pin connectors between products. The EK-OmniLink design resolves the cable clutter issues of unifying the connection of multiple fans onto a single PWM and D-RGB header while still maintaining full flexibility if the user wants to remove a single fan from the chain.
