Cooling - Water

These hydro-coolers allow anyone to water-cool their processor. They combine the pump, tubing, radiator and fans into a single, sealed unit that's simple to install and doesn't require maintenance or filling, and they're compatible with most Intel and AMD processors. Hydro-coolers provide superior cooling to a budget air-cooler, helping you reduce unwanted system noise and potentially enabling you to overclock the processor for added performance.

These particular hydro-coolers attach to a free 120 or 140mm fan mount in your case, and also require sufficient space to install the radiator.

These large hydro-coolers require attachment to a pair of free 120 or 140mm fan mounts side by side in your case, and also require sufficient space to install the radiator.

These extra-large hydro-coolers attach to three free 120 or 140mm fan mounts side by side in your case, and also require sufficient space to install the radiator.

These pre-selected kits are designed to make the transition to water-cooling easier, and contain all the blocks, pumps, radiators, reservoirs, tubing and fittings you need to create a fully functional water-cooling system, and many are supplied with coolant as well. You can be sure that each of the bits are compatible, and there's a range of kits to cater for systems with different requirements.

VGA coolers are the best way to cool your Graphics card when overclocking. This prevents damage to your components and can also decrease fan noise on certain graphics cards. Updated

Most of the water blocks here can be strapped to almost any CPU, including Intel and AMD processors, but it's important to check the socket you're using is compatible. They vary in their materials and colours, so you can easily match them to your system's aesthetics.

These are the smooth-faced chunks of metal that actually make contact with your components in a water-cooled rig. They can be used with processors, graphics cards, hard disks and chipsets, and many are only compatible with specific motherboards or third-party graphics cards, so double-check before you buy.

These blocks are designed to fit AMD's high-end single and dual-GPU graphics cards. Due to the complexity and variability of GPU PCBs, most are only compatible with reference designs or specific third-party models, so it's vital to check that your water block is compatible with your exact graphics card. Also take note of the thread size so you can connect your fittings and tubing properly. Finally, some blocks come with a backplate, while with others you can buy one separately, giving you the option to combine different colours and perfect your look.

These GPU blocks and accessories enable you to watercool your GeForce GTX 2080 Ti or 2080 graphics card based on the revolutionary new Turing architecture.

Watercooling a graphics card can make it cooler, quieter and potentially enable a bigger overclock.

Make sure you choose the right block for your specific graphics card.

Make the most of your GeForce GTX 1080 Ti, 1080, 1070 or Titan X Pascal graphics card, customising it with a waterblock for lower temperatures, lower noise and greater overclocking potential.

These products enable you to link together several watercooled graphics cards more easily and securely than connecting them with tiny pieces of tubing. Choose from a variety of colours, finishes and connections, enabling you to personalise your watercooling loop.

Pumps generate the motion required to push the water around your system. They come in various forms – some will fit into a spare drive bay, for example, and others have a reservoir attached. Whatever one you buy, you need to ensure it's powerful enough for your system, and that you have space in your chassis as well as a suitable spare power connector.

Reservoirs are not technically necessary, but are highly recommended. They increase your loop's fluid capacity and provide a convenient place to monitor water levels, add fluid or bleed air. Many can also be housed inside a spare 5.25in bay. This category also includes tubes, caps and other accessories.

The complexity and cost of custom water-cooling systems means it pays to keep an eye on them. The components in this category will allow you to track temperatures and flow rates and control fan speeds too. The 5.25in bay adaptors are useful for bringing these monitoring and control capabilities within easy reach at the front of you PC.

Hardline acrylic tubing looks stunning, but needs special fittings to hold the tubes in place compared to standard flexible tubing. The fittings in this category are all specially designed for hardline acrylic tubing and are available in a variety of colours and sizes to match the diameter of your tubing.

Fittings are a critical component in a watercooling loop as they secure the flexible tubing between the various components, such as the blocks, pump, reservoir and radiator. The fittings in this category are designed to secure 8/10mm (5/16"-7/16") tubing and pre-threaded for easy installation.

Fittings are a critical component in a watercooling loop as they secure the flexible tubing between the various components, such as the blocks, pump, reservoir and radiator. The fittings in this category are designed to secure 13/19mm (1/2"-3/4") tubing and pre-threaded for easy installation.

These products enable to easily add a fill port to your waterloop loop. When mounted at the highest point of a loop it allows you to easily fill and top-off the fluid, without having to dismantle your PC. Fill ports are not necessary, but make maintaining a watercooled PC much easier than a loop without one.
