1. EKWB EK-Quantum Kinetic TBE 200 D5 PWM D-RGB - Acetal
The expansion tank is equipped with a total of six G1/4" connections, allowing users to choose the optimal setup for their cooling loops. Three of these connections are located on the top, one of which features a pre-installed internal tube made of nickel-plated brass, preventing coolant from splashing in the tank when the top is used as an inlet. It also prevents air from being drawn in by the pump and keeps the coolant from foaming. Each of these connections can also be used to fill the system or to add additional accessories (thermal probes, LEDs, etc.). An additional three standard G1/4" connections are available on the lower housing. The upgrade from the previous combo unit is the third available side connection, which can be used as an optional inlet or drain. A special rubber damper is used to decouple the pump body from the mounting bracket, ensuring silent operation without noise caused by vibrations. Additionally, horizontal and vertical positioning is supported to simplify tubing routing. The tube, with a diameter of 60 mm, is made of high-quality acrylic material, while the bottom of the expansion tank and the top of the pump are made of CNC-machined black POM acetal. Sealing is achieved with a high-quality EPDM O-ring. The integrated addressable D-RGB lighting is compatible with the common RGB synchronization technologies of all major motherboard manufacturers.
