Product information

Description

EK-Quantum Scalar Flow Indicator is a GPU-mounted flow indicator with addressable D-RGB lighting and G1/4" inlet and outlet ports. It visually shows coolant flow rate and is designed to integrate with EK-Quantum Vector GPU blocks and backplates via an anodized black aluminium cover that matches the GPU water block finish. The unit uses a top-to-bottom flow pattern: liquid should enter the top right port and exit the side bottom port. The impeller body has a closed centre and sloped wings to reduce air trapping inside the indicator. The device includes two LEDs and is compatible with major motherboard manufacturers' addressable RGB (D-RGB / A-RGB) headers; align the arrow on the 3-pin connector with the +5V marking on the header. Installation requires following the labeled ports and the manual.

Advantages

The flow indicator provides an immediate, visual indication of coolant movement in a GPU cooling loop, helping to detect pump failures or flow issues that are otherwise difficult to observe. Its anodized aluminium cover hides LED hotspots for even illumination and visually matches EK GPU backplates. The sealed impeller design reduces air accumulation and the G1/4" ports ensure compatibility with standard water-cooling fittings.

Suitable for

  • Custom GPU water-cooling loops
  • Monitoring coolant flow in PC liquid cooling systems
  • Systems using EK-Quantum Vector GPU blocks and backplates
  • Builds requiring 1/4" (G1/4) threaded fittings

Key specifications

  • Type: Flow indicator
  • Mounting: GPU-mounted
  • Ports: G1/4" inlet and outlet (top-to-bottom flow)
  • Material: CNC machined cast acrylic body with anodized aluminium cover
  • Colour: Black, Transparent
  • Lighting: 2 addressable D-RGB LEDs, 3-pin connector (align arrow with +5V)
  • Compatibility: Compatible with major motherboard addressable RGB headers

How to use

Mount the flow indicator on the GPU as instructed in the product manual and confirm the correct orientation of the ports: connect the coolant inlet to the top right port and the outlet to the side bottom port. Use G1/4" threaded fittings to connect the indicator into your loop. Connect the 3-pin addressable LED cable to the motherboard D-RGB header, aligning the arrow on the connector with the +5V marking. Power up the system and verify visible impeller rotation and LED lighting to confirm proper flow and lighting operation.

Usage recommendations

Follow the manual closely and observe the port labels during installation. Ensure fittings are tightened to avoid leaks and that the D-RGB connector is aligned to +5V. Periodically inspect for trapped air and bleed the loop if necessary to maintain accurate flow indication.
