EK is releasing a series of unique flow indicators that belong to the Quantum Line. These Quantum flow indicators visually represent the coolant flow rate, which is often hard to see with the naked eye.

This can be very useful to instantly see if your loop operation is nominal or there’s trouble with the pump or flow in some other area as well as looking cool! It also features addressable RGB illumination where the LEDs are covered by a stylish black anodized aluminum cover to hide the hotspots. Aside from the standalone option, there are two more that mount directly on the EK-Quantum Vector GPU water block.

EK-Quantum Flow Indicator D-RGB
This standalone flow indicator features three G1/4″ ports, all of which are female. It can be mounted mid tube run with two fittings or fastened to any G1/4″ port on a radiator, pump, or even a block via the use of a dual male-threaded extender. Any of the threads can be used as either inlet or outlet. It can be used in a straight flow-through setup, or it can replace a 90° angled fitting, or a 90° bend in your loop.

EK-Quantum Scalar Flow Indicator D-RGB
These GPU-mounted flow indicators are made to replace the stock terminal with the one integrating the flow indicator. They come in two variants, with either top-bottom flow or bottom-top flow pattern. Flow patterns are mandatory to be followed for proper operation of the indicators.
