Water Cooling Case

If you’re after a PC that can handle serious gaming and deliver on performance, water cooling is the way to go. It’s more efficient than air cooling methods, which means it takes less energy to maintain safe temperatures and supports your PC to run at peak performance.

Unfortunately, not all PC cases support water cooling. Investing in a water cooling case would be the ultimate choice if you need reliable water cooling capacity for extended periods of time. Having a water-cooled setup ensures your rig will stay cool and well-ventilated, allowing for maximum effectiveness that air cooling does not provide.

Furthermore, you may want it not only to ensure that all of your components are efficiently cooled but also to serve as an incredible showpiece, with dazzling illumination effects that look great in any setup.

We have taken it upon ourselves to search through all the best cases out there and bring you what we consider to be the ultimate list: Our picks for the Best Water Cooling Cases. With this guide, you’ll be sure to find a perfect match for your dream builds.

How to Select the Best Water Cooling Case

PC Case Size

PC case size definitely matters and can determine how efficient water cooling modules will be. Full-tower or mid-tower cases are usually the best bet for water cooling, as there tends to be more space for water components like radiators, water blocks, pumps, and reservoirs.

The larger the computer case, the more water-cooling components can be installed while maintaining adequate airflow. But if you prefer a mini-tower or small form factor (SFF) case, water cooling kits are now available that are designed to fit these smaller cases. Either way, when selecting your water cooling case, it’s important to take into the account water flow and where the radiators and pumps should be placed. That’s definitely an important consideration when trying to make sure your build is as efficient as possible.

AIO or Custom Water Cooling?

Picking out the right water cooling case is crucial to ensure proper cooling. It depends on what type of system you’re looking for. All-in-One (AIO) systems are much more popular, but if you want to get really fancy and personalize your build, custom water cooling can take it to the next level.

The most important aspect of a case is making sure there’s enough space to mount all the necessary hardware while still having decent cable management options. If you’re aiming for custom water cooling, then you’ll also need to consider how much room is available for the reservoir as well.

So whatever path you choose for your build, make sure you take this into account when selecting your case.

Radiator Size

There are many different water cooling cases available, so deciding which one is right for you takes a bit of research. When making your decision, make sure to consider things like the maximum size of the radiator that the case supports, as it is important to ensure that your water cooling system can cool the components effectively.

Generally, full-tower cases offer bigger radiators that can handle up to 360mm (which equates to 3x 120mm fans). Mid-tower cases typically have radiators that are 240mm (2x 120mm fans) or 280mm in size (2x 140mm fans). However, it’s best to double-check the details of each individual case since sizes can differ from model to model. That way you’ll ensure that your PC receives optimal cooling performance.

You will also need to find out where to install the radiator and other components within the water cooling case to ensure optimum efficiency. Doing some comparison shopping and weighing up all of the features of various water cooling cases is also a good idea – it’ll mean you can be sure that you’re making the best choice when deciding on your water cooling setup.
