When considering water cooling, one question comes to mind: is there a specific order in which the liquid cooling components should be placed? Today we plan to give a short and clear explanation of the recommended order.
Simple custom outline This handy illustration depicts the liquid cooling circuit in its simplest form. Starting from the bottom and moving clockwise, you will see that the reservoir feeds the pump, which then pushes the liquid into the water block (s) and then into the radiator to exchange heat with the surrounding air to complete the cycle in the reservoir.
The pump requires fluid to constantly flow through it otherwise you risk damaging the motor (fluid acts as a lubricant in addition to keeping the pump itself from overheating – especially in the case of D5). After the reservoir and pump, you can customize your circuit in almost any configuration you want.
What about more complex paths?
It is recommended to keep the flow as high as possible in order to reduce the temperature difference between the units in the circuit. This becomes a more serious problem if multiple GPU and CPU units are added to the same circuit, resulting in a higher refrigerant temperature. Although this difference is usually only a couple of degrees Celsius, it can have a slight impact on system overclocking performance.
This can be corrected by placing blocks with similar limiting properties (for example, the same GPU blocks) in a parallel configuration so that each block receives the same flow and theoretically has the same temperature.
Heatsinks are usually placed directly in front of the reservoir to dissipate heat in front of the pump, but you can install heatsinks between block arrays: the largest heatsink in front of the GPU and the smallest heatsink in front of the processor for optimal thermal performance if your chassis can accommodate it.
Always position the reservoir in front of your pump (a pump / reservoir combination is best for this). Also, consider using a parallel configuration when cooling multiple GPU waterblocks for more even flow. Otherwise, the components can be placed as desired, as this does not significantly affect the cooling performance.
