Q: Does loop order matter?
A: Since our Pump/Reservoir Combo unit is both pump and reservoir, there is no need to worry about the order of the remaining parts.

Q: Can I use Hydro X Series blocks with aluminum blocks/fittings?
A: No, Hydro X Series blocks use a cold plate made of nickel-plated copper and should not be mixed with aluminum parts in a liquid cooling loop.

Q: Can I run this as a standalone part?
A: No, the Hydro X Series are intended for use as part of a complete custom cooling system, including standalone pump and radiator.

Q: Can I use tap water or distilled water as coolant?
A: For the best performance, protection and longevity of the cooling system we recommend using pre-mixed fluid with corrosion, biological and scale inhibitors such as CORSAIR XL5 Performance Coolant. You should never fill or flush your custom cooling system with tap water, as it contains high levels of particulates and minerals that will damage and clog your system. Distilled water can be used to flush the system, and as a coolant, but requires corrosion, biological and scale inhibitors to be added for long-term use.

Q: How can I clean the Hydro X Series components?
A: Internally, flush with distilled water. Externally, use a lint-free cloth to remove marks or fingerprints.

Q: How often do I need to change fluid?
A: We recommend changing your custom cooling system’s fluid every 12 months to remove particulate build-up and ensure optimal thermal performance.

Q: Is the XL5 coolant non-conductive?
A: While the XL5 coolant has a very low conductivity level, no coolant can be deemed “non-conductive” since any coolant will slowly become conductive when put in contact with metal such as radiators and water blocks. While it would technically be correct to say on the bottle that the coolant is non-conductive, this would be misleading to our customers as it would no longer be true as soon as the coolant is added to the custom cooling system.

Q: Can I reuse the pre-applied thermal material on the XC or XG Series RGB Water Blocks for re-installation?
A: Re-installation of the water blocks will require you to clean off the pre-applied thermal paste and apply a new layer of thermal material. However, the thermal pads fitted to the GDDR and VRMs can be reused.

Q: How many water blocks and radiators can one Pump/Reservoir Combo support?
A: This unit delivers a head pressure of 3.9 meters, powerful enough to provide adequate flow through a custom cooling loop of at least four water blocks and three radiators.
