Doorstroomindicator EK Water Blocks zwart transparant 1/4 inch

EK-Quantum Scalar Flow Indicator is a GPU-mounted flow indicator with addressable D‑RGB lighting, designed to show coolant flow visually and match the finish of EK-Quantum Vector GPU water block backplates. The device has a black anodized aluminum cover and a transparent acrylic body, and it mounts to the GPU using dedicated G1/4" In and Out ports. This variant uses a bottom-to-top flow pattern and incorporates an impeller with a closed centre and sloped wings to reduce air entrapment. The housing contains two LEDs and the cover evens out lighting to hide hotspots.

Advantages

The indicator provides an immediate visual indication of loop flow, allowing quick detection of pump or flow issues. Its G1/4" threaded In and Out ports are clearly labelled to ensure correct installation, and the bottom-to-top flow design is optimised to prevent trapped air. The anodized aluminum cover matches EK GPU block finishes while reducing LED hotspots for uniform lighting. Compatibility with major motherboard RGB sync standards allows integration with addressable D‑RGB (A‑RGB) headers.

Suitable for

• Custom GPU water-cooling loops with G1/4" fittings
• Systems using EK-Quantum Vector GPU water blocks and backplates
• Setups requiring visual confirmation of coolant flow

How to use

Install the flow indicator into the GPU cooling loop following the port labels: connect the inlet to the loop feed at the bottom-side port and the outlet to the top-side port so coolant flows bottom-to-top. Secure all G1/4" fittings and check for leaks before powering the system. Connect the 3‑pin addressable LED cable to the motherboard D‑RGB/A‑RGB header, aligning the connector arrow with the header's +5V marking. Consult the product manual for detailed installation diagrams and torque recommendations.

Recommendations

Always follow the manual and verify correct inlet/outlet orientation before filling the loop. Use compatible G1/4" fittings, ensure the 3‑pin D‑RGB connector is aligned with +5V, and perform a leak test with the pump running but the system powered off where applicable.
