Frequently asked questions
Which Alphacool 360mm radiator is best for tight cases?
The NexXxoS ST30 360mm X-Flow is the ideal choice for space-constrained builds. It features a slim 30mm profile, which is significantly thinner than the Monsta’s 3.39-inch depth. This design allows for straightforward tube routing and better clearance in compact chassis. You get a copper core in a 16.3-inch length without the bulk of thicker options.
Does the Monsta have more ports than other 360mm models?
No, the Monsta does not offer more ports than several alternatives. The UT60 series, including the white and black versions, provides six G1/4-inch connection ports. This matches the port count of the XT45 models. You gain flexible multi-port routing options with the UT60 without needing the extreme 86mm thickness of some other high-capacity radiators.
Is there a white option similar to the Monsta?
Yes, the Alphacool NexXxoS UT60 360mm White Radiator is available for white builds. It shares the all-copper internals of the Monsta but offers a 60mm thickness instead of 3.39 inches. This model includes six G1/4-inch ports for versatile plumbing. It suits builders who want premium materials and multi-port flexibility in a white aesthetic.
How does the XT45 differ from the Monsta in thickness?
The XT45 360mm Copper Radiator is much thinner than the Monsta. It measures 46mm in depth, compared to the Monsta’s 3.39-inch profile. This reduced thickness balances liquid volume with broader PC case compatibility. You get dependable heat transfer through all-copper internals and six G1/4-inch ports, making it suitable for standard mid-tower cases where the Monsta might not fit.
What is the X-Flow layout used for?
The X-Flow layout provides an inline flow configuration for specific tube routing needs. Models like the ST30 and XT45 X-Flow use this design to offer cross-flow port layouts. This is helpful when standard dual-port radiators do not fit your tube runs. You gain streamlined hardware clearance and versatile routing options in space-limited or complex custom loop builds.
Which radiator is heaviest among the 360mm options?
The UT60 360mm White Radiator is the heaviest option listed. It weighs 3.87 pounds, which is more than the Monsta’s 1.5 pounds. This weight comes from its all-copper construction and 60mm thick core. The UT60 X-Flow is also heavy at 3.17 pounds. These models deliver high thermal capacity but require robust case mounting support.
Can I use a 360mm radiator in a small form factor case?
You can use a 360mm radiator in small cases by choosing a slim model. The ST30 360mm X-Flow has a 30mm profile and weighs only 1.51 pounds. Its slim design trades raw core volume for streamlined tube routing. This makes it easier to fit in cases where the deeper Monsta or thicker UT60 models would obstruct other components.
