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

All EK-Quantum flow indicators are CNC-machined out of cast acrylic material, and these variants come with nickel-plated aluminium covers. The aluminium cover is also there to cover any LED hotspots, as proper LED implementation is one of EK's key missions when designing a product. The flow indicator features a unique impeller body with a closed center and sloped impeller wings that prevent air from being stuck inside the indicator.

RGB Compatibility
These products are compatible with popular RGB sync technologies from all major motherboard manufacturers. The arrow marking on the 3-pin LED connector is to be aligned with the +5V marking on the D-RGB (aRGB) header.

Availability and Pricing
The EK-Quantum Flow Indicator D-RGB - Nickel is available for order through the EK Webshop and dedicated reseller network, while nickel Scalar Flow Indicators are available for pre-order and expected to ship out on September 15, 2020.
