DIY Water Cooling

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.

The importance of choosing the right sort of water or coolant for your watercooling loop shouldn’t be underestimated. Don’t be tempted to use standard tap water as it's full of particles and bacteria that over time will clog up the loop reducing its effectiveness and making the tubing and reservoir look a prop from a Roger Corman film.

This category contains a variety of premixed coolant in a huge variety of colours, including some that are UV reactive. Being premixed, the coolant already contains anti-algae and corossion inhibitors, so you can simply fill up your loop without having to worry about needing any additives.

This category contains a huge variety of optional accessories that can help improve the functionality or look of your watercooled PC.

Adding a flow meter to the loop allows you to monitor the flow rate of the coolant, giving you an early warning of any problems. They also look cool whirling away.

Combining one or more temperature sensors with compatible software allows you to monitor the temperature of the coolant, giving you an early warning of any problems. You can also use them to adjust the fan and pump speed if the temperature is too high or you want to reduce noise.

Leak testers comprise a hand-operated pump that uses air pressure to easily test your watercooling loop before filling it with coolant and potentially experiencing a nerve-wracking leak.

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 reservoirs. 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. 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.

This category contains a huge variety of 80, 120 and 140mm radiators. The radiator and associated fans conduct heat out of the coolant and into the surrounding air.

Radiators come in four main sizes, 80/120/140mm for a single fan, 240/280mm for two fans, 360/420mm for three fans and 480/560mm for four fans. The larger the radiator the more heat it can conduct. Large radiators have a side benefit which is that you can use slower and quieter fans. If space permits you boost performance by mounting fans on both sides of the radiator in a push-pull configuration.

Radiators also come in different thicknesses, anywhere from around 25mm up to 60mm. Thicker radiators are theoretically capable of conducting more heat but will require more powerful fans to push air between the radiator’s fins.

This category contains a huge variety of flexible tubing. This is easy to work with and is available in a variety of colours, including transparent so you can see the coolant inside.

Tubing is used to transfer the coolant between all the aforementioned components of the loop. Make sure you consider the size, it’s important to check the internal and external diameter of the tubing to ensure it's compatible with the other components in the loop. As a general rule of thumb, the larger the diameter the lower the temperatures as there will be more water in the loop. The downside is that larger diameter tubing is more awkward to work with and may not fit at all in smaller cases.

This category contains a huge variety of hardline tubing fittings. Fittings are used to secure the different components of the loop to the tubing. You’ll need two fittings (one in, one out) for each component, making sure that they are the right diameter for your tubing. Fittings are available in a wide variety of finishes so you can match them to the rest of the loop. Fittings are even available in different shapes, including 45° and 90° angles, y-splitters and x-splitters.
