Our top pick: Alphacool ES HPE-60 Copper 80mm Quad Radiator.

Comparing these radiator alternatives

Alphacool NexXxoS XT45 120mm Copper Radiator

The Alphacool NexXxoS XT45 120mm Copper Radiator shifts your focus to a standard 120mm fan footprint. While the original ES HPE-60 offers a dense quad configuration in an 80mm space, this model provides a more common mounting solution for wider cases. It weighs just 1.32 pounds and measures 4.88 by 6.18 inches, making it significantly lighter and more compact than the heavy 3.45-pound copper block. You gain easier installation in standard chassis but lose the high-pressure industrial rating and the ability to fit four fans in a tight 80mm envelope. This is the better choice if you prioritize space efficiency and standard fan compatibility over extreme pressure tolerance.

Alphacool NexXxos UT60 120mm Copper Radiator

The Alphacool NexXxos UT60 120mm Copper Radiator offers a different approach to compact cooling with its multi-port design. It measures 4.72 by 4.72 inches with a height of 2.76 inches, providing a square footprint that differs from the rectangular ES HPE-60. At 1.76 pounds, it is much lighter than the original’s 3.45 pounds, reducing stress on your mounting points. You trade the original’s reinforced weld seams and 5-bar pressure rating for greater port flexibility and a smaller physical profile. This option suits builders who need multiple connection points in a small area and do not require the heavy-duty industrial specifications of the quad radiator.

Alphacool NexXxos ST30 120mm Copper Radiator

The Alphacool NexXxos ST30 120mm Copper Radiator is defined by its minimal thickness. Standing only 1.18 inches tall, it is far slimmer than the 1-inch wide but deeper original ES HPE-60. Weighing just 0.47 kilograms, it is the lightest option here, offering significant weight savings compared to the 3.45-pound original. You sacrifice the original’s high-pressure capability and dense quad-fan layout for a ultra-compact form factor that fits into tight spaces. This radiator is ideal for small form factor builds where height is restricted. You get efficient single-fan cooling without the bulk, making it a practical choice for constrained PC cases.

Alphacool NexXxoS XT45 Full Copper 180mm Radiator

The Alphacool NexXxoS XT45 Full Copper 180mm Radiator expands your cooling surface area significantly. Measuring 8.78 by 7.17 inches, it is much larger than the compact 80mm original. At 1.06 kilograms, it is lighter than the original but offers more cooling potential for a single fan setup. You gain a larger heat exchange surface suitable for higher heat loads but lose the ability to mount four fans in a small 80mm space. This model is best for users who have case space for a 180mm mount and need robust copper performance without the industrial pressure ratings of the original quad radiator.

Alphacool NexXxoS XT45 Full Copper 180mm Dual Radiator

The Alphacool NexXxoS XT45 Full Copper 180mm Dual Radiator provides double the surface area of the single 180mm version. It measures 14.2 inches in length and weighs 3.8 pounds, slightly heavier than the original ES HPE-60. You gain substantial cooling capacity for high-heat components but require a case that supports dual 180mm mounts or a very long single mount. The original offers a dense 80mm quad layout, while this provides a long, dual-channel solution. This is the right choice if you have ample case space and need maximum copper cooling performance, accepting the larger footprint and weight increase.
