As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
The Alphacool NexXxoS HPE-30 Full Copper is a slim 30mm radiator built for tight cases. It features a pure copper core with twelve cooling channels and five G1/4-inch ports. This design offers a practical foundation for standard 360mm liquid cooling loops. You might look for alphacool nexxxos hpe 30 full copper alternatives if you need more mounting clearance or different port layouts. Some builds require thicker cores for higher thermal capacity, while others need straight-through flow routing for cleaner tubing paths. The original model’s slim profile limits its surface area compared to bulkier options. You may also prefer a different size, such as a 480mm unit for quad-fan setups. Alternatively, you might want a white finish to match a specific aesthetic. We selected these alternatives because their specifications overlap with the original. Each option shares the 360mm or larger size category and uses copper construction. This ensures they serve similar cooling roles while addressing specific spatial or routing needs. You can choose based on your case dimensions and preferred connection styles.
Our top pick: Alphacool NexXxoS HPE-30 360mm Copper Radiator.
Comparing HPE-30 Alternatives
Alphacool NexXxoS XT45 360mm Copper Radiator
The Alphacool NexXxoS XT45 moves to a thicker 46mm profile, which provides more core volume than the HPE-30's 30mm design. It retains the all-copper construction but adds a sixth G1/4-inch port for easier tubing routing. This extra thickness requires more clearance inside your case. You should choose this if you have space for a 46mm depth and want more connection points. The wider profile may limit fitment in compact chassis where the slimmer HPE-30 fits easily.
Alphacool NexXxos UT60 360mm Copper Radiator
The NexXxoS UT60 doubles the thickness to 60mm, significantly increasing the copper core volume compared to the HPE-30. It offers six G1/4-inch ports for flexible loop planning. This unit is strictly for spacious cases that can accommodate the extra depth. You gain thermal capacity and routing options but lose the ability to mount it in tight spaces. If your chassis has ample room, the UT60 provides a more robust heat dissipation surface than the slim HPE-30.
Alphacool NexXxos UT60 360mm White Radiator
This white variant of the UT60 shares the same 60mm thick copper core and six-port layout as its black counterpart. It offers substantial thermal mass for high-performance loops. The white finish suits builds with specific aesthetic goals. Like the black UT60, it requires generous case clearance. You trade the compact 30mm form factor of the HPE-30 for a much larger cooling surface. Select this if you prioritize aesthetics and have the physical space to mount a thick radiator.
Alphacool NexXxoS XT45 X-Flow 360mm Radiator
The XT45 X-Flow features a 45mm thickness with an end-to-end flow design. This layout allows for straight-through tubing routing, which simplifies plumbing compared to the side-mounted ports on the HPE-30. It maintains the full copper build for reliable heat transfer. You gain easier tube routing but sacrifice the slim 30mm profile. This option suits builders who need streamlined tubing paths and have the case depth to support the thicker core.
Alphacool NexXxoS ST20 HPE Copper 360mm Radiator
The ST20 HPE is a slim 20mm radiator, thinner than the 30mm HPE-30. It uses pure copper construction to fit into even tighter spaces. You get a more compact footprint but likely less thermal mass than the HPE-30. This model is ideal for ultra-compact cases where every millimeter counts. If your priority is fitting a 360mm setup into a restricted area, the ST20 offers the smallest profile while maintaining copper performance.
Alphacool NexXxoS ST30 480mm Full Copper Radiator
The ST30 scales up to a 480mm size while keeping the slim 30mm profile. It supports four fans instead of three, providing more surface area for heat dissipation. This option is for large cases that can accommodate the extra length. You gain significant cooling potential by adding a fourth fan zone. If your chassis allows for a 480mm mount, this provides more cooling capacity than the 360mm HPE-30 without increasing thickness.

Frequently asked questions
Is there a 360mm copper radiator with a thinner profile than the HPE-30?
No. The ST20 HPE Copper is the thinnest 360mm option listed, measuring 0.79 inches or roughly 20mm. It uses pure copper construction to provide heat dissipation for builds with very limited mounting clearance. This slim frame makes it suitable for compact enclosures where space is at a premium.
Which copper radiator offers the most connection ports for tubing?
The XT45, UT60, and UT60 White models all feature six G1/4-inch ports. The XT45 provides six ports in a 46mm profile, while the UT60 series offers six ports in a thicker 60mm core. These extra ports allow for more flexible tubing routing in custom loops compared to the five-port HPE-30.
Can I use a 480mm copper radiator in a standard case?
Only if your case has sufficient length. The ST30 480mm Full Copper Radiator is designed for large cases needing quad-fan cooling. It maintains a slim 30mm profile while providing massive surface area. You must verify your chassis supports the longer 480mm dimension before installation.
What is the difference between the XT45 and XT45 X-Flow?
The XT45 X-Flow features an end-to-end flow routing layout, which allows for straight-through tube connections. The standard XT45 uses a traditional multi-port design. Both use full copper construction, but the X-Flow version is better for streamlined tubing routing in roomy cases.
Which copper radiator is best for a white custom loop?
The UT60 360mm White Radiator is the ideal pick for white aesthetics. It delivers heavy-duty thermal capacity with a 60mm thick copper core and six connection ports. You need ample chassis room to accommodate its extra thickness, but it fits well in spacious builds with white themes.
Does the ST20 HPE use the same core as the HPE-30?
Both are slim copper radiators, but the ST20 is thinner at 20mm compared to the 30mm HPE-30. The ST20 provides 360mm heat dissipation in a 0.79-inch frame. It is built strictly for compact enclosures requiring the thinnest possible copper cooling solution.
