The EK Quantum Kinetic3 FLT 240 D5 PWM D-RGB Plexi is a premium reservoir and pump combination designed for custom liquid cooled PC builds. Its flat, 240mm format design offers a space efficient solution for integrating coolant storage and circulation into a custom loop, with mounting options suited to compatible cases and radiator style layouts. The transparent acrylic construction allows coolant levels and flow to remain visible, while integrated D-RGB lighting adds customisable illumination to your system. An integrated D5 PWM pump provides adjustable coolant circulation through compatible PWM control, allowing users to tailor pump speed to their cooling requirements. The built-in reservoir maintains a supply of coolant to the pump, while multiple G1/4 inch threaded ports provide flexibility for tubing layouts and loop connections. Designed for enthusiast water cooling systems, the EK Quantum Kinetic3 FLT 240 D5 PWM D-RGB Plexi combines pump performance, reservoir functionality and RGB lighting in a streamlined format for custom gaming and workstation builds.
Features

EK-Quantum Kinetic³ FLT 240 D5 PWM D-RGB - Plexi
This next-generation EK-Quantum Kinetic³ FLT D5 pump-reservoir combo unit builds on the success of the existing FLT, flat-style combo unit and further improves compatibility, and simplifies the installation process by moving the pump to the front side and implementing additional G1/4“ connection ports.
It comes with sophisticated addressable D-RGB lighting and a genuine D5 pump.
The unit features standard 120mm fan mounting holes for maximum flexibility during the installation. The reservoir is equipped with a total of eight G1/4“ ports so that users can choose the most optimal setup for their liquid cooling loops.
EK-Quantum Kinetic³ FLT D5 series pump-reservoir units are equipped with genuine D5 pumps, made in Europe, which are capable of delivering flow rates of 1000 litres per hour with a maximum head pressure of up to 5.2 meters. These new FLT series combo units are available in six different sizes 92mm, 120mm, 240mm, 140mm, 280, and 360mm.

The new Kinetic³ flat-shaped pump-reservoir units are to revolutionise the way you were thinking about combo units and loop building. Since 120mm fan mounting patterns (105mm apart) are the most dominant mounting options inside PC cases these days, these new Kinetic FLT D5 combo units will allow greater flexibility for installation since they don't require drilling of mounting holes on your case. The combo unit is also equipped with additional mounting points on both sides (105mm apart) which can be used with the included steel L-shaped mounting plates. All mounting holes utilise M4 threads with the included screws.
The reservoir is manufactured of premium quality acrylic material, and machined to perfection, while the sealing is performed by a custom-formed high-quality EPDM O-ring. Alongside the reservoir is a black anodised aluminium cover under which the Addressable D-RGB LED strip is placed. Proper LED implementation is one of the main focus points of EK so that there are as few visible "LED hotspots" as possible. The cover is now a standalone piece, easily removable at any time if the LED strip requires any service or replacement.
Please Note:
- Do not clean the reservoir with alcohol derivates or other solvents as the acrylic may crack.
- Coolant and additional plugs are just for showcase and are not delivered with the product.
- The D5 pump is water lubricated and it must not be run dry; otherwise, permanent bearing damage can occur.
