You&#39;ve assembled the key components of your custom loop. Now you need water cooling fittings that connect everything securely and keep coolant flowing exactly where it should. CORSAIR fittings are built to hold up under the demands of a high-performance custom liquid cooling build, whether you&#39;re running a soft tube loop or a rigid hardline setup.

A PC water block is the core component of any custom liquid cooling loop. It mounts directly to your CPU, GPU, or other heat-generating component, drawing heat away from the die and into the coolant that circulates through your system. If you&#39;re building a high-performance custom cooling loop, choosing the right waterblock is one of the most important decisions you&#39;ll make.

A water cooling radiator is a core component of any custom liquid cooling loop. It works by absorbing heat from the coolant circulating through your system and dissipating that heat into the surrounding air with the help of mounted fans. Whether you&#39;re building a high-performance gaming rig, a content creation workstation, or an overclocked CPU setup, choosing the right PC radiator directly impacts how well your system manages thermal load.

A CPU water block is the component that mounts directly onto your processor, transferring heat away from the die and into the coolant circulating through your custom loop. If you&#39;re building or expanding a custom liquid cooling system, the CPU water block is the core piece that connects your processor to the rest of the loop, keeping temperatures in check during sustained workloads, gaming sessions, and overclocking runs.

If you&#39;re pushing your graphics card hard, a GPU water block gives you a direct path to lower temperatures and more stable performance. By replacing the stock cooler with a precision-machined water block, you route coolant directly over the GPU die, VRAM, and VRMs, pulling heat away far more efficiently than air cooling allows. Browse our full range to find a water block built for your card.

A pump reservoir combo simplifies your custom liquid cooling loop by integrating the coolant storage and circulation pump into a single, compact unit. Instead of sourcing and mounting these two components separately, you get a cleaner build with fewer fittings, less tubing, and a more streamlined installation. Whether you&#39;re building your first custom loop or upgrading an existing setup, a pc water cooling pump and reservoir combo is a practical choice for managing space and reducing complexity.
