DIY Water Cooling

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.

The coolants here are both aesthetically pleasing and highly functional. They are designed to prevent corrosion and the growth of algae, both of which would prove problematic and reduce your systems cooling ability. Pre-mixed solutions are available in a wide variety of colours, including UV reactive ones.

These concentrated coolants are designed to be mixed with deionised water to fill your water-cooled PC. Choose a wide variety of colours and finishes.

Customise the look of your watercooling loop with these water dyes. Choose a single dye or consider mixing different dyes together to create your perfect colour.

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.

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.

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.

If you're short on space inside your PC then you you should consider one of these pump/reservoir combos, which as the name suggest comprise a pump and reservoir mounted together in one space-saving device.

The pump is absolutely critical, pushing fluid around the watercooling loop. These accessories allow you to personalise your pump, including special mounts that make it easier to position the pump inside your case.

Customise and personalise the reservoir in your watercooling loop with these handy accessories.

The radiators here can only be used with a single fan or a fan on either side. They're designed to make the very most limited space, and are particularly well suited to small form factor cases.

The radiator, when combined with one or more fans helps to conducts heat energy from the fluid in the watercooling loop into the air away from your PC. The larger the surface area the more effective the cooling, although some radiators are so thick they will only perform well with special fans that have a very high static air pressure to move air between the fins of the radiator. The radiators in this category require at least two 120mm fans to cool adequately.

The radiators in this category require at least six 120 or 140mm fans to cool adequately.

Tubing is what connects all the various components of your water-cooling system together. It's flexible, and can be cut to the length you require. The tubing in this category is sized 3/8” inner diameter (ID) and 1/2” outer diameter (OD), and is suitable for both barb and compression hose fittings. It's available in a range of colours and those listed as UV will glow under UV light.

Tubing is what connects all the various components of your water-cooling system together. It's flexible, and can be cut to the length you require. The tubing in this category is sized 3/8” inner diameter (ID) and 5/8” outer diameter (OD), and is suitable for both barb and compression hose fittings. It's available in a range of colours and those listed as UV will glow under UV light.

Acrylic tubing is non-flexible. As well as cutting, it requires manual bending, but the end result of straight lines and sharp angles is visually stunning and it's available with special finishes too. Pay attention to the internal and external diameters measure up so you know the length you need.
