Water Cooling Pumps
At the heart of every custom loop is a reliable water cooling pump. These essential components ensure steady coolant flows throughout your system, maintaining optimal temperatures for your CPU and GPU. Whether you're running a compact loop or a full tower with multiple radiators, the right pump makes all the difference in thermal performance and system stability. Overclockers UK stocks a wide range of water cooling pumps, including the popular D5 and DDC models, known for their power, reliability, and modularity. You’ll also find integrated pump-reservoir combos for easier installation and a cleaner aesthetic. Choose between PWM or voltage-controlled units to suit your set-up, and enjoy quieter, more efficient cooling. No matter your loop size or complexity, we have the perfect pump to keep your system flowing strong.
How To Choose The Right Pump
Not all water cooling pumps are created equal. Choosing the right water cooling pump is essential for achieving reliable flow and optimal thermal performance in your custom loop. Whether you're running a compact build or a sprawling setup with multiple components, there are three main pump types to consider: D5, DDC, and combo units. Each offers unique benefits in terms of size, power, noise levels, and installation flexibility, so it's important to match your pump to your PC’s specific demands.
- D5 Pumps: Renowned for their high flow rate and near-silent operation, D5 pumps are a favourite among enthusiasts building larger, more complex loops. Their cylindrical design is often housed in a larger body, making them better suited for mid- to full-tower cases. With superior reliability and smooth performance, D5 pumps excel in pushing coolant through multiple radiators, GPU blocks, and longer tubing runs.
- DDC Pumps: DDC pumps offer similar performance to a D5, but in a much smaller footprint. This makes them ideal for SFF (small form factor) or compact cases where space is at a premium. They run slightly louder and hotter than D5s under heavy load, but with the right mounting and cooling, they deliver powerful performance in tight builds.
- Combo Pumps: Combo units integrate the pump with a reservoir into a single compact device, reducing the number of components in your loop and simplifying installation. Available in both D5 and DDC variants, these are perfect for users who want to save space and minimise tubing while keeping maintenance straightforward. They're especially helpful for first-time loop builders or anyone wanting a cleaner internal layout.

What does a water cooling pump do?
A water cooling pump circulates coolant through your custom loop, moving it between components like the CPU block, GPU block, radiators, and reservoir to maintain optimal temperatures.
What is the difference between D5 and DDC pumps?
D5 pumps are larger and quieter with high flow rates, ideal for big loops, while DDC pumps are more compact and powerful, making them better suited for small form factor builds.
Do I need a pump/reservoir combo?
Pump/reservoir combos simplify loop design, reduce tubing, and are easier to install, making them a great choice for first-time builders or space-conscious setups.
