Should I Buy a Standalone Unit or a Reservoir-Pump Combo?

It doesn’t matter if you buy standalone or a combo. I would recommend buying a combo because these combo units exactly meets with your demand.

If you want to customize your build on your own then, it would be better to take separate components.

But, it’s very time consuming to build and join everything accurately. If any misplacement occurs then, whole build can rupture in seconds.

Whereas, the combo kits are joined and easier to connect to other components.

Reservoir-Pump Combo Ultimate Buyer’s Guide

A good combo unit is needed in order to flow the liquid perfectly in the cooling loop.

You need to consider certain aspects before buying a reservoir/pump combo unit.

Here are some things you should consider for buying a reservoir-pump combo unit:

Anti-Cyclone Feature

Some reservoirs don’t have this feature and hence a tornado is created within the reservoir because of gravity. This coolant cyclone can damage the whole cooling system and make you cashless within seconds.

You don’t want this sort of things to happen to your cooling loop. And so, Corsair Hydro X series XD5 is the best option for you in such cases because of the anti-cyclone feature present in tis combo unit.

Reservoir Capacity

Reservoir capacity is very important in case of building a custom cooling loop.

Your amount of coolant and reservoir capacity should not mismatch. Or else, it will be difficult for the pump to transfer the coolant from reservoir to radiator. EK-Quantum Kinetic FLT 360 has a reservoir capacity of 435 mL which is enough for the coolant flow.

Noise-Reduction Feature

I personally don’t want noise in my cooling loop and so I recommend a zero noise anti-vibrating combo.

Thermaltake Pacific PR22-D5 w/ Silent Kit Combo and Corsair Hydro X series XD5 is the best when it comes to keeping a silent environment.
