Water block EK Water Blocks 3831109829899 Nickel Silver Transparent
EK-Quantum Flow Indicator D-RGB is a premium flow indicator from the Quantum Line that makes coolant movement in custom liquid cooling loops visible. The device helps determine at a glance whether the loop flow is nominal or if there is an issue with the pump or restricted flow. Constructed from cast acrylic and finished with a nickel-plated aluminum cover, the indicator combines functional visibility with a compact, metal-clad design.
The flow indicator provides a clear visual representation of coolant flow rate through a uniquely designed impeller with a closed centre and sloped wings that prevent air entrapment. It includes three female G1/4" ports and supports addressable D-RGB lighting compatible with major motherboard RGB sync standards. A nickel-plated aluminum cover conceals LED hotspots to produce even illumination across the device.
Install the indicator inline within the tubing run using two G1/4" fittings or attach it to a G1/4" port on a radiator, pump, or block with a dual male-threaded extender. Connect the 3-pin addressable LED connector to a +5V D-RGB (A-RGB) header on the motherboard, aligning the arrow marking with the header's +5V marking. Any of the three ports may be used as inlet or outlet; choose the orientation that matches your loop layout and secure fittings to ensure a leak-free connection.
Check flow visually after initial filling and during first run to confirm there are no trapped air pockets; the impeller design minimizes air retention but visual verification ensures correct loop operation. Ensure the D-RGB connector is aligned correctly to avoid lighting issues and use appropriate G1/4" fittings rated for coolant systems.
