Frequently asked questions
Can I use these radiators with the Alphacool ES RTX 4080 block?
Yes, you can pair any of these radiators with the GPU block. The block cools the graphics card, while the radiators dissipate heat from the loop fluid. You simply need to connect them using compatible tubing and fittings. This combination allows you to build a complete custom liquid cooling system tailored to your specific case size and thermal requirements.
Which radiator is best for a slim server rack build?
The NexXxoS ST30 480mm is ideal for slim server racks. It maintains a compact 30mm thickness while offering a 480mm length for quad-fan setups. This design fits dense enclosures where space is limited. Its full copper construction ensures efficient heat transfer without requiring excessive depth, making it a practical choice for tight server installations.
Do I need a thick radiator for heavy overclocking?
A thick radiator like the NexXxoS UT60 360mm provides substantial cooling volume. Its 60mm all-copper core delivers heavy-duty thermal capacity for demanding workloads. This depth allows for more heat exchange surface area. You should only choose this option if your case can accommodate the extra depth required for maximum thermal performance.
What is the difference between the XT45 and UT60 radiators?
The XT45 offers a standard 45mm profile, while the UT60 features a thicker 60mm core. Both are 360mm copper radiators, but the UT60 provides greater thermal mass. The XT45 is suitable for standard builds, whereas the UT60 suits spacious loops needing extra cooling headroom. Your choice depends on whether you prioritize profile height or maximum heat dissipation.
Are these radiators compatible with white PC cases?
The NexXxoS UT60 360mm White Radiator is designed for white builds. It features a white finish that matches modern aesthetic themes. It retains the heavy copper construction and multi-port connectivity of the standard black version. This option allows you to maintain a cohesive look in your custom loop without sacrificing the thermal performance of a full copper core.
Is there a smaller radiator option for single-fan setups?
The NexXxoS XT45 180mm Copper Radiator is sized for single-fan mounts. It provides a full copper cooling surface with a 1.77-inch profile. This compact size is perfect for targeted cooling in smaller cases. It delivers reliable performance for custom loops that require a minimal footprint while still utilizing the efficient heat transfer properties of copper.
How does the X-Flow design affect cooling performance?
The XT45 X-Flow 360mm Radiator uses an all-copper build with a 1.77-inch profile. This design ensures dependable liquid cooling with moderate thickness. It offers a solid balance between size and thermal capacity. The X-Flow structure helps manage fluid dynamics efficiently, providing consistent performance for standard 360mm fan mounts in compatible chassis.
