How each alternative compares
Alphacool NexXxoS XT45 360mm Copper Radiator
The Alphacool NexXxoS XT45 360mm Copper Radiator increases thickness to 46mm, providing more material for heat dissipation than the 45mm HPE-45. It offers six G1/4-inch ports instead of five, giving you slightly more flexibility for fittings and drain lines. The XT45 uses a full copper core similar to the HPE-45, ensuring consistent thermal performance across the loop. You should choose this model if you prefer a thicker radiator for better cooling potential or need an extra port for complex routing. The wider profile may not fit in cases with strict height limitations.
Alphacool NexXxos UT60 360mm Copper Radiator
The Alphacool NexXxoS UT60 360mm Copper Radiator steps up to a 60mm thickness, significantly increasing the surface area for cooling compared to the 45mm HPE-45. It retains the six G1/4-inch port configuration found in the XT45, offering ample connection options. The all-copper construction ensures high thermal capacity, making it suitable for high-TDP CPUs. This option is ideal if your case has the depth to accommodate the thicker unit and you prioritize maximum cooling performance over compactness. The added weight and depth require careful planning for case compatibility and airflow.
Alphacool NexXxos UT60 360mm White Radiator
The Alphacool NexXxoS UT60 360mm Radiator in White matches the 60mm thickness and copper internals of the UT60 black version, offering superior cooling capacity to the 45mm HPE-45. It features six G1/4-inch ports for versatile loop routing. The primary difference is the white finish, which helps maintain a specific aesthetic in white-themed builds. You should pick this if you need the extra cooling performance of a 60mm radiator but require a white color to match your components. The increased thickness demands more space within your case chassis.
Alphacool NexXxos ST30 360mm X-Flow Radiator
The Alphacool NexXxoS ST30 X-Flow 360mm Radiator reduces thickness to 30mm, making it much slimmer than the 45mm HPE-45. It uses a straight-through X-Flow port design, which simplifies tubing routing compared to the multi-port layout of the HPE-45. The full copper core maintains good thermal performance in a low-profile package. This is the best choice if you have limited case depth or prefer a minimalist look. You trade some cooling potential and port flexibility for a significantly smaller footprint that fits into tighter spaces.
Alphacool NexXxoS XT45 X-Flow 360mm Radiator
The Alphacool NexXxoS XT45 X-Flow 360mm Radiator maintains a 45mm thickness, similar to the HPE-45, but switches to an X-Flow port configuration. This design aligns ports on opposite ends, allowing for straight tubing runs rather than the multi-directional routing of the HPE-45. The full copper core provides comparable thermal performance. Choose this model if your loop layout benefits from end-to-end fluid flow and you want to avoid angled fittings. It offers a streamlined look and easier tubing management for builders who prefer simple, straight paths.
Alphacool NexXxos UT60 X-Flow 360mm Radiator
The Alphacool NexXxos UT60 X-Flow 360mm Radiator combines the 60mm thickness of the UT60 series with the X-Flow port layout. It offers higher thermal capacity than the 45mm HPE-45 while simplifying tubing routing with straight-through connections. The six G1/4-inch ports provide ample connection points for complex loops. This radiator is suited for spacious cases that can handle the extra depth. You gain cooling performance and routing simplicity but lose the multi-directional port flexibility of the HPE-45. It is a robust option for high-performance builds with ample internal space.

Frequently asked questions
Is the XT45 better than the HPE-45 for tight cases?
The XT45 is not better for tight cases because it is slightly thicker. It measures 46mm in height, while the HPE-45 is 45mm. This small difference matters if you have minimal clearance. The XT45 offers six ports instead of five, which helps with flexible routing. You should choose the HPE-45 if your case has very limited vertical space.
Can I use a white radiator with the HPE-45 loop?
Yes, you can use a white radiator in the same loop. The UT60 in white features a full copper core like the HPE-45. It provides six G1/4-inch ports for easy connection. The white finish matches aesthetic builds without sacrificing thermal performance. Just ensure your case can handle the extra 60mm thickness of the UT60 compared to the 45mm HPE-45.
What is the difference between X-Flow and standard ports?
X-Flow ports allow liquid to pass straight through the radiator. The ST30 and XT45 X-Flow models use this design for streamlined routing. Standard ports, like those on the HPE-45, are located on the sides for multi-port flexibility. X-Flow is ideal for simple loops. Standard ports are better for complex setups with multiple components.
Which Alphacool radiator is the thinnest option?
The ST30 X-Flow is the thinnest option at 30mm. It fits in slim cases where the HPE-45 would not fit. The ST30 uses a copper core for good heat dissipation. It weighs 1.51 pounds and measures 16.3 inches long. Choose this model if your case has only 30mm of available space for a radiator.
Does the UT60 provide more cooling than the HPE-45?
The UT60 likely provides more cooling due to its increased thickness. It is 60mm thick, compared to the 45mm HPE-45. More material allows for greater heat dissipation capacity. The UT60 also has six ports for versatile loop integration. If your case allows the extra space, the UT60 offers higher thermal potential than the slimmer HPE-45.
How many ports does the HPE-45 have compared to others?
The HPE-45 has five G1/4-inch ports for flexible routing. Most other models in this list have six ports. The XT45, UT60, and UT60 X-Flow all offer six connection points. This extra port helps when connecting multiple components or adding a drain line. The HPE-45 balances port count with its slim 45mm profile.
