Water Cooling Kits
If you're ready to move beyond standard cooling options, a custom water cooling kit for PC gives you direct control over temperatures, noise levels, and the look of your build. CORSAIR's water cooling kits bring together the core components you need to build a custom loop, whether you're cooling just your CPU or running a full-system setup that covers your GPU as well.
What's Included in a Custom Water Cooling Kit?
If you're ready to move beyond standard cooling options, a custom water cooling kit gives you direct control over temperatures, noise levels, and the look of your build. CORSAIR's water cooling kits bring together the core components you need to build a custom loop, whether you're cooling just your CPU or running a full-system setup that covers your GPU as well.
A water cooling kit typically bundles the essential components of a custom loop into a single purchase, removing some of the guesswork around compatibility and sourcing individual parts. Depending on the kit, you can expect to find some or all of the following:
- Pump & Reservoir: A standalone pump and reservoir, or a combined pump-reservoir unit
- Radiator: A radiator sized to fit your case
- CPU Water Block: A dedicated block to draw heat away from your processor
- Tubing, Fittings & Coolant: Everything needed to connect and fill your loop
This makes a custom water cooling kit a practical starting point for builders who want a custom loop without sourcing each component separately.
Choosing the Right Kit & Expanding Over Time
Before you pick a kit, consider what you want to cool. A CPU-only loop is simpler to build and maintain, while a CPU and GPU setup delivers more coverage for high-output rigs running demanding workloads or extended gaming sessions. You'll also want to think about your case's radiator support — check the maximum radiator size your case accommodates, since 240mm, 360mm, and larger options all affect airflow and thermal capacity differently.
Tubing style matters too. Soft tubing is more flexible and easier to route, while hardline tubing offers a precise, clean look that many builders prefer for a showpiece build. Some kits are designed specifically for one tubing type, so check the contents before committing.
One of the key advantages of starting with a custom water cooling kit is that you can expand it over time. Once your initial loop is running, adding a GPU block or a second radiator is a realistic next step. CORSAIR's custom liquid cooling ecosystem includes individual components — from fittings and radiators to water blocks and coolants — so you can build on your kit as your system evolves.
