Top rated Water cooling pumps
Here’s a ranking of the top rated Water cooling pumps. To give you a quick overview, we’ve added the most important information about each product. This page always stays fresh and updates automatically.
1. EKWB Uni pump holder
Planning a custom water cooling system is not for the faint of heart, as there are many details to consider. One should also be clear about the positioning of the pump. With the black EK-UNI pump holder, selected pumps can be positioned horizontally or vertically depending on the orientation of the fan. The extensive accessories from EK Water Blocks leave nothing to be desired.

2. EKWB Ek-Uni pump bracket (120mm fan)
The four or eight holes in the center of the bracket are compatible with M4 threaded screws. This allows the pumps of the EX-XTOP and EK-XRES Revo D5 series to be installed without additional accessories. On the other hand, the EK-XTOP DDC series requires additional materials for installation, namely EK-DDC vibration dampers, an EK-DDC heatsink housing, and an EK-UNI DDC V2 bracket.

3. Alphacool VPP655 Single Edition
Alphacool's new power pump series offers exceptional performance at an unbeatable price. The 12V pumps can be easily connected to the power supply and start up along with the computer, ensuring maximum convenience and safety.
This pump is ideal for water cooling of PCs and other electronic components. The DC motor pump is equipped with an electronically commutated spherical motor. In a pump with a spherical motor, the only moving part is a spherically shaped rotor that rests on a bearing ball made of ultra-hard and wear-resistant ceramic. The spherical bearing of the rotor provides numerous advantages: an increase in bearing play is structurally impossible, and the pump consistently operates quietly and smoothly. A separate magnetic shielding is also unnecessary for this pump. The ball motor principle allows for efficient operation with excellent performance. All parts of the pump are completely corrosion-resistant. The pump is simply powered via a 12V Molex connector from the PC power supply.

4. 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.

5. Alphacool Vpp655 Pwm
For years, this attachment has been a benchmark. Small improvements have been made repeatedly. The second major update differs both visually and technically in a few details. The principle: there is space for the Laing D5 or VPP655 on the underside, with inlet and outlet at the front and on the top. For even more flexibility, the ice cover features three inlets and two outlets. Another feature is the new mounting bracket, which provides a stable base for the entire unit and enhances the overall visual appeal. Optionally, installation in a 3.5" bay is also possible. The attachment can be transformed into a complete expansion tank with the help of the optional expansion tank adapter, which has also been revised. For all case modders, the acrylic attachment includes four holes for 5mm LEDs.

6. Alphacool Vpp6553
This pump is ideal for water cooling of PCs and other electronic components. The DC motor pump is equipped with an electronically commutated spherical motor. In a pump with a spherical motor, the only moving part is a spherical rotor that rests on a bearing ball made of ultra-hard and wear-resistant ceramic. The spherical bearing of the rotor offers a variety of advantages: an increase in bearing play is structurally impossible, and the pump always operates quietly and smoothly. A separate magnetic shielding is also unnecessary for this pump. The ball motor principle allows for efficient operation with excellent performance. All parts of the pump are completely corrosion-resistant. The pump is easily powered by a 12V Molex connector from the PC power supply. The special feature of this model is that only the pump core is supplied. After all, one would want to connect the pump to an alternative cover or expansion tank; why pay more for the surrounding components? Another feature is located on the back: with a small twist, the pump can be adjusted to five different pumping levels.

7. Aqua Computer D5 Next RGB
With the D5 NEXT, Aqua Computer presents a coolant pump based on the Laing D5, featuring an excellent range of functions. The detachable control unit is equipped with an OLED display and a powerful PWM fan output. An RGBpx effect controller for 64 addressable LEDs is also integrated.

8. Aqua Computer Aquastream Ultimate Version
The Aquastream Ultimate was specifically designed for PC water cooling systems and meets all set goals with powerful electronics, integrated fan control, temperature measurement, an OLED display, and various control options. Additionally, the extremely quiet operating noise of the pump is worth mentioning.

9. Aqua Computer ULTITUBE D5 150 PRO expansion tank with D5 NEXT pump
The AGB from Aqua Computer in the Pro version features a D5-NEXT pump made of durable borosilicate glass with a capacity of 350 ml. It includes a stainless steel filter and a pressure equalization membrane, as well as mounts for floor or wall installation and RGBpx lighting.

10. Aqua Computer ULTITUBE D5 100 PRO expansion tank with D5 NEXT pump
AGB from Aqua Computer in Pro version, equipped with a D5-NEXT pump, made of durable borosilicate glass with a filling volume of 230 ml. It includes a stainless steel filter and a pressure equalization membrane, as well as brackets for floor or wall mounting and RGBpx lighting.
