## Long description

The EK-Quantum Kinetic³ FLT D5 is a flat-style pump-reservoir combo designed for custom PC liquid cooling loops. This next-generation unit improves compatibility and simplifies installation by positioning the genuine D5 pump on the front face and adding multiple G1/4" threaded ports. The reservoir body is made from acrylic with a high-quality EPDM o-ring seal and is covered by a removable black anodized aluminum shroud that houses an addressable D-RGB LED strip. The unit supports standard 120 mm fan mounting patterns and is available in multiple lengths to suit different loop layouts.
Advantages
The combo integrates an authentic European-made D5 pump capable of up to 1000 liters per hour flow and a maximum head pressure of 5.2 meters, offering reliable performance for demanding cooling loops. Its flat design and 120 mm fan-hole footprint enable flexible installation without requiring case modifications, and additional side mounting points with included L-shaped steel brackets expand mounting options. Nine G1/4" ports provide multiple inlet/outlet configurations while the removable LED cover reduces visible lighting hotspots and allows easy service access.

Custom PC liquid cooling loops in mid-tower and full-tower cases
