    Take your PC’s performance and aesthetics to the next level with custom water cooling. Whether you’re chasing lower temps, silent operation, or a stunning showpiece PC, water cooling offers unbeatable flexibility and results. Overclockers UK stocks a whole host of water-cooling components compatible with the latest Intel, NVIDIA and AMD PC components. You can find CPU and GPU blocks, tubing, fittings, radiators, and reservoirs, all of which work in sync to keep your hardware cool under heavy loads. Plus, with options for soft and hard tubing, vibrant coolants, and powerful pumps, building your perfect loop has never been easier. Whether you're just starting out or you're a seasoned enthusiast, Overclockers UK has everything you need to design, customise, and maintain your ultimate water cooling set-up.


    Water-cooling Explained

    • CPU Water Blocks: These sit on top of your processor and transfer heat into the coolant, keeping your CPU running cool under pressure.
    • GPU Water Blocks: Designed to cool your graphics card, these are essential for high-end GPUs or overclocked set-ups where heat output is significant.
    • Radiators: Radiators dissipate heat from the coolant with the help of fans, keeping temperatures low and performance high.
    • Pumps: Pumps move the coolant through your loop, ensuring consistent flow and effective heat transfer across all components.
    • Reservoirs: Reservoirs hold excess coolant and make it easier to fill, bleed, and maintain your water cooling loop.
    • Tubing and Fittings: These connect every component, available in both soft and hard variants depending on your layout and aesthetics. Fittings ensure a secure, leak-free connection between components and come in various types like compression, rotary, and angled for added flexibility.
    • Coolant: Coolant flows through the entire system, with clear, dyed, or additive-enhanced fluids to match your build and prevent corrosion.
    • Distro Plates: Distro plates combine reservoirs and coolant channels into a single component, simplifying loop design and adding visual flair.
    • Quick Releases: Quick-release fittings allow for easy disconnection of components without draining the loop, ideal for upgrades and maintenance.
    • Monitoring Tools: Tools like flow meters, sensors, and temperature probes help you fine-tune performance and ensure optimal system health.

    Water Cooling FAQ


    How effective is water cooling?

    Water cooling is highly effective, offering superior thermal performance and lower noise levels compared to traditional air cooling, especially in high-performance systems.

    Is water cooling really better than air cooling?

    Water cooling typically outperforms air cooling in heat dissipation and acoustic performance, making it ideal for overclocked CPUs, GPUs, and enthusiast-level gaming PCs.

    What do I need for a custom water cooling loop?

    A complete custom loop requires a CPU or GPU block, radiator, reservoir, pump, tubing, fittings, and coolant.

    Is custom water cooling hard to install?

    Custom water cooling can be complex for beginners, but with planning and the right tools, it’s a rewarding upgrade that offers excellent cooling performance and incredible style.
