## Summary description

The EK Water Blocks 3831109829721 is a flow indicator designed for computer cooling systems. It features a black and transparent design with a 1/4" connecting thread, allowing for easy integration into your cooling loop. This component helps monitor the flow of coolant, ensuring optimal performance and preventing overheating.

## Long 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

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.
