What goes into a Watercooled PC?


 Fans are mounted directly onto the radiator to create airflow and cool it down. the fans can operate at lower speeds than traditional air coolers, resulting in a quieter and more efficient cooling solution for your system.

Water Blocks

Water blocks replace air coolers or AIO liquid CPU coolers to efficiently transfer heat from the processor or graphics card to the liquid.

The pump pushes the coolant through the loop, while the reservoir, often connected to the pump, stores the coolant and acts as the primary filling point for the system.


Fittings serve as the connecting pieces between tubing and components, such as water blocks, in a custom water-cooling system. The tubing connects all the components in a single loop and carries the coolant from one part of the system to the next.
