Article Text
For more than a decade, Alphacool has dominated the market with the NexXxoS Full Copper radiator series. Our extensive portfolio of radiator variants is unique in the world. Just like our manufacturing process, which allows us to produce all water-carrying parts and the cooling fins out of pure copper. As a result, the NexXxoS series offers the highest thermal conductivity of any radiator on the market. 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 NexXxos Full Copper HPE Radiator uses the same materials as previous NexXxos models but takes it a step further technically. Due to the 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 the heat transfer is enormously improved. The higher number of fin rows and their shortening also makes much more efficient use of the cooling surface. Comparison tests* with the conventional NexXxos radiator have shown that a performance increase of 4.5K is possible when using the HPE radiator. At higher ambient temperatures and higher fan speeds, the performance gap with the normal NexXxoS radiators even increases progressively, reaching a possible performance increase of up to 6K.
* Test setup: NexXxos ST30 360mm radiator vs. NexXxos HPE-30 360mm radiator with Eisbaer cooler and 3x 120mm Rise Aurora fans and on Asus Prime x299 motherboard with Intel i9 10900x CPU with 350W waste heat
Connection Options & Mounting
The NexXxoS HPE radiator has two IN or OUT connections with G1/4" threads in the pre-chamber area. On the opposite side is a fill or drain port, which can be used for filling and draining the water circuit. All screws for mounting in the case and for mounting the fans are included with the radiator. Additional screws are not usually required.
Safety First
The NexXxoS HPE radiator has special protective plates placed under all mounting holes to prevent the screws from being screwed in too deeply. This protects the cooling fins and water channels underneath from damage.
Patented Screw Plugs
All NexXxoS HPE radiators use Alphacool's patented screw plugs. Protruding screw plugs often mean that the radiator cannot be laid flush. Alphacool's screw plugs are fully recessed into the radiator, flush with its surface, and allow easy installation in the case.
Dimensions and Drawings
A detailed technical drawing of the Alphacool NexXxoS HPE-45 Full Copper 140mm Radiator shows multiple views. One view displays the top with G1/4" ports and dimensions. Another shows a side profile. Isometric views illustrate the overall structure and port placement. Key dimensions indicated include overall length of 173.5mm, width of 144mm, and thickness of 45mm. It also shows port thread details like G1/4" and M3x0.5-6H, and fin density (FPI).
The product image shows a black, rectangular radiator with two large, square-shaped end tanks. The Alphacool logo and "HPE" are visible on the top surface. The radiator fins are densely packed and visible through the top ports.
