If your PC has high-end components that generate a lot of heat, then it is extremely important to cool them properly in order to avoid any damage or performance throttling. The best way to that is to use water cooling solutions, since they are much more efficient than air-cooled solutions when it comes to cooling. However, liquid cooling systems are oftentimes big and chunky, so you’ll need to use a specially optimized PC case to install such solutions.
