Cooling - Water

Need help? Read our Water Cooling Buying Guide

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.

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.
