EK, the premium liquid cooling gear manufacturer from Europe, is releasing another series of flow indicators that belong to the Quantum Line. These Quantum flow indicators visually display the coolant flow rate, which is often hard to see with the naked eye. This allows you to instantly see if your loop operation is nominal or there's trouble with the pump or flow in some other area. It also makes the loop look even cooler! It features addressable RGB illumination where the LEDs are covered with a stylish nickel-plated aluminium piece that hides hotspots. Aside from the standalone version, there are two more that mount directly on the EK-Quantum Vector GPU water blocks. All three come with nickel-plated aluminium cover.

This standalone nickel-plated flow indicator features three female G1/4" ports. It can be mounted in the middle of a tube-run with two fittings or fastened to any G1/4" port on a radiator, pump, or even a block by using a dual male-threaded extender. Any of the ports can be used as either inlet or outlet. It can be installed in a straight flow-through setup, or it can replace a 90° angled fitting or a 90° bend in your loop.
