If you want to have the pump with the highest possible throughput for your water cooling system, you should use the Laing D5. But it's not perfect in one respect: the non-standard connections. Like other manufacturers, Bitspower also offers alternative D5 covers. The completely transparent cover, milled from one block of acrylic, has three G1/4" threaded holes and holes for LEDs. The transparent look makes LEDs and coloured coolants particularly effective. Included in delivery are the necessary screws and a sealing ring.
