6 Best Alternatives to the Alphacool Eisball Reservoir Pump Combo (2026)
As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
You might be looking for alphacool eisball reservoir pump combo alternatives because the original unit does not fit your specific chassis or loop design. The Alphacool Eisball 700ml D5 Reservoir offers a large 700 ml capacity in a transparent nylon sphere. It integrates a D5 pump and Digital RGB lighting into a single 128 mm high unit. This all-in-one platform works well for high-capacity builds. However, you may need a different form factor or a separate pump. Some builders prefer a flat reservoir or a cylinder design. Others already own a pump and only need a top. You might also want addressable lighting or a different port configuration. We selected these alternatives because their specifications overlap with the original. Each option shares key traits like D5 compatibility or acrylic construction. This list covers seven products that serve as direct substitutes. You can choose based on your available space and lighting preferences. The following sections detail the specs for each ranked item.
How each alternative compares
Alphacool Eisball D5 Reservoir and Pump Top
The Alphacool Eisball D5 Pump Top Reservoir shares the same 700 ml transparent nylon sphere and Digital RGB lighting as the original. The key difference is that this unit is a pump top only. It lacks the integrated D5 pump found in the Eisball combo. You must already own a D5 pump to use it. This makes it lighter at 1.42 pounds compared to the original's 2.03 pounds. Its height is slightly taller at 5.04 inches versus 4.63 inches. Choose this if you already have a pump and want the spherical aesthetic without buying a second pump.
Alphacool Eisdecke D5 Plexi Pump Top
The Alphacool Eisdecke D5 Plexi Pump Top is a compact acrylic top for standalone D5 pumps. It does not include a reservoir or pump. It offers five ports for tubing routing, which provides more flexibility than the integrated combo. It is much smaller at 3.15 inches square and weighs only 0.44 kilograms. It lacks Digital RGB lighting, relying on clear coolant visibility instead. This is a budget-friendly option for builders who want a minimal footprint. It suits those who prefer a traditional pump mount over a large spherical reservoir.
EK-Quantum Kinetic TBE 200 D5 Plexi Combo
The EK-Quantum Kinetic TBE 200 D5 Plexi Combo is a cylindrical unit with integrated D5 pump and addressable D-RGB lighting. It replaces the sphere shape with a vertical cylinder design. It features six G1/4-inch ports for versatile tubing connections. The lighting is addressable, allowing for more complex color effects than standard Digital RGB. It is taller at 7.79 inches but narrower at 3.07 inches wide. This option is best for builders who want upright cylinder aesthetics. It provides similar all-in-one convenience but with a different visual style and more port options.
EKWB EK-Quantum Volume FLT 240 Acrylic Reservoir
The EKWB EK-Quantum Volume FLT 240 is a flat acrylic reservoir with addressable D-RGB lighting. It is designed for standalone pumps, not as an integrated combo. It features a slim profile measuring 19.7 inches in length and width. It includes four G1/4-inch ports for loop connections. The lighting is addressable, offering customizable patterns. It lacks an integrated pump, so you must supply your own. This is ideal for flat reservoir setups in cases with limited vertical clearance. It provides a modern, low-profile alternative to the bulky spherical design of the original Eisball.
EK Quantum Reflection² PC-O11D EVO Plexi Distro Plate
The EK Quantum Reflection² PC-O11D EVO Plexi Distro Plate is an integrated pump solution for specific cases. It fits O11D EVO cases directly. It includes a D5 pump and acts as a distribution plate. It lacks a large reservoir, relying on the case's internal volume or smaller reservoirs. It is black acrylic, contrasting with the transparent original. It simplifies builds by combining pump and distribution functions. This is a niche option for O11D EVO owners. It offers a compact, integrated approach but sacrifices the large 700 ml reservoir capacity of the original unit.
