EK-Quantum Impulse 120 D-RGB - Black (400-1800 rpm) 3831109854198 Features: Three Premium LED-Lit Zones Unlike other EK fans, which have LEDs exclusively in the rotor, Impulse fans have additional LEDs on both sides of the frame. MagLev and VAPO Bearing The VAPO bearing adds a magnetic effect (magnetic levitation) to the bearing to reduce noise and increase shaft stability. Square Frame for Airflow Focusing The practical square shape of the fan frame provides optimal performance in either the pull or push regime without hydraulic losses, which ensures the optimal cooling capacity of your liquid cooling radiators. Standard D-RGB Connectors The EK-Quantum Impulse 120 fan's D-RGB lighting does not require any fancy or expensive additional controller for you to enjoy vibrant light effects. A simple 3-pin 5V addressable D-RGB connection for standard controllers or any popular D-RGB (ARGB) sync technology from major motherboard manufacturers is all you need. OmniLink The ability to daisy chain fan power, D-RGB, and even pump power across a single cable gives you the ultimate flexibility while reducing cable clutter. All the cables are flat ribbon style with no additional sleeving for an even better cable routing experience.
