Details
The Alphacool NexXxoS HPE-30 Full Copper 140mm Radiator is a 140 mm radiator for one 140 mm fan, 30 mm thick, for a custom water cooling loop. Its IN/OUT connections have G1/4 threads, a fill or drain port sits on the opposite side, and the color is black.

NexXxoS Full Copper
Alphacool says it has dominated the market with the NexXxoS Full Copper radiator series for more than a decade, and calls its extensive portfolio of radiator variants unique in the world. Just like the portfolio, it points to its manufacturing process, which allows it to produce all water-carrying parts and the cooling fins out of pure copper. As a result, in Alphacool's words, the series offers the highest thermal conductivity of any radiator on the market. Alphacool adds that, thanks to their exceptional performance, the radiators can easily dissipate even extremely high waste heat and have become essential in many areas of the cooling industry.
The next step in evolution: NexXxoS HPE Full Copper Radiator!
The HPE radiator uses the same materials as previous NexXxos models, but Alphacool takes it a step further technically. Due to a condensed internal structure, the number of water channels and copper fins could be increased. Thus a larger volume of water is in direct contact with the cooling fins, and Alphacool describes the heat transfer as enormously improved. It says the higher number of fin rows and their shortening also makes much more efficient use of the cooling surface.
Alphacool reports comparison tests with the conventional NexXxos radiator that have shown a possible performance increase of 4.5K when using the HPE radiator. At higher ambient temperatures and higher fan speeds, it says the performance gap with the normal radiators even increases progressively, reaching up to 6K. Alphacool gives us the test setup: a NexXxos ST30 360mm radiator vs. a NexXxos HPE-30 360mm radiator, each with an Eisbaer cooler and 3x 120mm Rise Aurora fans. It ran on an Asus Prime x299 motherboard with an Intel i9 10900x CPU at 350W of waste heat, so both figures belong to the 360 mm size. Alphacool's data sheet adds 1.2x increased water throughput and 20% more efficient heat transfer compared to the NexXxos standard, with 100% of the internal structure made of copper.
Connection options & mounting
Alphacool's text describes two IN or OUT connections with G1/4 threads in the pre-chamber area, while its table counts 4x G1/4 IN/OUT. A loop uses two of them, one in and one out, so the radiator takes two G1/4 fittings, each with a thread no longer than 5 mm. The fill or drain port on the opposite side can be used for filling and draining the water circuit. The radiator holds a 140 mm fan on M3 threads. All screws for mounting in the case and for mounting the fans are included with the radiator: four M3x5 case mounting screws and four M3x30 fan screws. Additional screws are not usually required.
Safety first
Special protective plates are placed under all mounting holes of the radiator. They prevent the screws from being screwed in too deeply, which protects the cooling fins and water channels underneath from damage.
Patented screw plugs
All NexXxoS HPE radiators use screw plugs that Alphacool has patented. Protruding plugs often mean that a radiator cannot be laid flush. Alphacool's screw plugs are fully recessed into the radiator and flush with its surface, which it says allow easy installation in the case. The box lists a plug tool and no loose plugs.
