Cooling - Water

Water-cooling is perfect for those looking to achieve the lowest temperatures and noise levels with overclocked components. Water-cooling loops involve combinations of water blocks, tubing, fittings, radiators, pumps, reservoirs and coolant, and since many of these come in a wide range of colours, it can also be used to create some seriously attractive and jealousy-inducing PCs and case mods. CPUs, GPUs, motherboards and even memory sticks can be water-cooled, but please be aware that the use of this equipment may void the warranty of your system or components.

120mm to 140mm Single Fan AIO Hydro Coolers

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.

240mm to 280mm Dual Fan AIO Hydro Coolers

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 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.

CPU Water Blocks

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.

Chipset Blocks

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.

AMD Graphics Card Blocks & Backplates

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.

Water Pumps

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.

Sensors, Monitoring & Controls

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.

540mm/560mm Radiators & Accessories

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 six 120 or 140mm fans to cool adequately.
