Cooling - Water

NVIDIA GeForce RTX 50-series graphics cards produce a lot of waste heat, and without sufficient cooling will overheat, shutting down or damaging your system. Watercooling provides the ultimate in cooling and aesthetics.

This category contains a huge variety of waterblocks that replace the heatsink and fan on NVIDIA GeForce RTX 50-series graphics cards, conducting heat away from the hot running components underneath into the coolant that flows through the interior.

Make sure you choose a waterblock that is compatible with your NVIDIA graphics card. You not only need to check which GPU(s) each waterclock is compatible with, but also which graphics card are compatible, as different card manufacturers use custom PCBs.

NVIDIA GeForce RTX 40-series graphics cards produce a lot of waste heat, and without sufficient cooling will overheat, shutting down or damaging your system. Watercooling provides the ultimate in cooling and aesthetics.

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.

AMD and Intel CPUs produce a lot of waste heat, and without sufficient cooling will overheat, shutting down or damaging your system. Watercooling provides the ultimate in cooling and aesthetics.

This category contains a huge variety of waterblocks that mount on top of the CPU, conducting heat away into the coolant that flows through the interior.

Make sure you choose a waterblock that is compatible with your CPU. If you're not sure check your component documentation or our buyers guide.

CPUs and motherboards produce a lot of waste heat, and without sufficient cooling will overheat, shutting down or damaging your system. Watercooling provides the ultimate in cooling and aesthetics.

This category contains a huge variety of combo waterblocks that cool both the CPU and select components on the motherboard such as VRMs, conducting heat away into the coolant that flows through the interior.

As motherboard design varies enormously make sure you choose a waterblock that is compatible with your motherboard.

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.

Cooler running electronic components such as memory chips last longer, so why not consider watercooling the RAM in your PC. These watercooled memory kits include a set of DDR4 DIMMs of varying capacities for desktop PCs, plus a waterblock that attachs to the DIMMs. Plumb this into a watercooling loop and you could lower the memory temperature by as much as 37%. The waterblock also includes a programmable RGB lighting system for extra standout.

PC components produce a lot of waste heat, and without sufficient cooling will overheat, shutting down or damaging your system. Watercooling provides the ultimate in cooling and aesthetics.

This category contains a variety of watercooling kits which include the CPU waterblocks, pump, radiator, reservoir, tubing and fittings you need to create a fully functional watercooling loop, most are supplied with coolant as well. Buying a kit means you don't need to worry about compatibility between all the components. It's also worth noting that you can easily upgrade and expand the loop with additional components such as a GPU waterblock at a later date.

Before you start browsing it’s important to know what sort of case you have, as these kits are available with different size radiators, typically 240mm or 360mm.

This category contains a huge variety of pumps. The pump is the beating heart of a watercooling loop, moving the coolant between all the other components. Loops with multiple waterblocks and large radiators will require a more powerful pump than a basic loop. The pump has to be securely mounted to the case, so make sure to use a sound absorbing mount, otherwise the pump will cause the whole case to vibrate and make a right old racket.

This category contains a huge variety of combo pump/reservoirs. These generally take up less space than separate components, and are more convenient than buying a pump and reservoir separately.

The pump is the beating heart of a watercooling loop, moving the coolant between all the other components. Loops with multiple waterblocks and large radiators will require a more powerful pump than a basic loop. The reservoir stores extra coolant in the loop and helps separate air bubbles from the coolant as it passes through. This is important as excess air bubbles will reduce the effectiveness of the waterblocks, radiator and pump, leading to increased temperatures and unnecessary noise.

This is important as excess air bubbles will reduce the effectiveness of the waterblocks, radiator and pump, leading to increased temperatures and unnecessary noise. Most reservoirs are made of transparent plastic so you can see the coolant, and are available in a wide variety of shapes, sizes and finishes, including RGB lighting.
