EK-Quantum Scalar Flow Indicator is a premium GPU-mounted flow indicator with addressable RGB implementation belonging to the Quantum Line. It visually represents 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 is operation is nominal or there's trouble with the pump or flow in some other area. Aside from that, it perfectly blends with your GPU block and backplate due to the aesthetic anodized aluminum cover that matches the finish of the GPU water block backplate.
