    Unleash Ultimate Cooling Power – Discover Premium Components for Perfect Water Cooling

    With a custom water cooling system, your PC will be quieter and cooler. The advantage over an AIO is that you can integrate your graphics card, motherboard, and even your SSD into a self-built water cooling loop. This way, all the PC components relevant to your gaming PC's performance are cooled with water and can unleash their full potential.

    We offer water cooling components for custom loops from the following manufacturers:

    • EK Water Blocks
    • Corsair
    • Alphacool
    • Phanteks
    • BitsPower

    Build your own water cooling system and achieve the best temperatures

    The topic of water cooling may seem complex and time-consuming at first glance. With the right accessories, however, you will definitely not have any problems building your next water cooling system.

    What do I need for a custom water cooling system?

    • Reservoirs
    • Distro Plates
    • Pumps
    • Radiators
    • Tubes
    • Controllers
    • Water Additives

    The biggest and most important part of your water cooling loop is the tubes or hard tubes and the fittings that hold your circuit together. They connect the water coolers of graphics cards, CPUs, and other components with the reservoirs and radiators. Therefore, they must be absolutely leak-proof so that your valuable hardware is not prematurely damaged.

    Additional accessories for water cooling systems

    Other categories are also essential for building a reliable water cooling system:

    Coolant with various colours and effects

    Water additives bring colour to water cooling systems and give the coolant impressive colours or light effects (e.g., UV activity). Coolants for improving thermal properties or additives for enhanced corrosion protection are also in demand.

    Ball valves and shut-off valves for easy maintenance of the water circuit

    Shut-off and ball valves allow flexible interruption of the cooling circuit, for example, to subsequently disconnect individual components for maintenance or to refill coolant.

    O-rings prevent liquid damage

    Sealing rings reliably protect the hardware from contact with water. Remember to also replace the O-rings in long-standing water cooling loops. Wear on the seals can cause your loop to no longer be leak-proof.

    Bridging external and internal threads

    Spacer rings and sleeves are sealed spacers that can be used, for example, as spacers between longer external and shorter internal threads.

    Water cooling adapters facilitate the construction of your cooling circuit

    Adapters can be used to connect different connection formats.

    Secure hold of your tubes with compression fittings

    Compression fittings not only look chic, but they also ensure safety in water cooling systems by securely holding the tube or hard tube.

    Openings in reservoirs and the case lid for filling the loop

    Water fill ports are fill nozzles that make it easier to fill the water circuit through an opening in the case lid or directly at the reservoir.

    Flow sensors to measure the flow in your system

    With flow sensors, you are on the safe side because you always have the flow in your water cooling loop in view. They are available in analogue form, in which they purely indicate the current flow through movement. There are also digital versions that display the flow rate in litres per minute and issue warning signals if the flow rate is too low.

    Configure and buy water cooling systems at Caseking

    If you want to build your custom water cooling system, Caseking is definitely the right place. We offer you everything you need for building your custom loop and are happy to assist you with any questions or problems.
