Alphacool NexXxoS HPE-30 Full Copper 560mm Radiator, 140mm, G1/4, 30mm, Black (14471)

The Alphacool NexXxoS HPE-30 Full Copper 560mm Radiator is a 560 mm radiator for four 140 mm fans, 30 mm thick, with all water-carrying parts and the cooling fins made of pure copper.

Properties

• Fans: 4x 140 mm one-sided / 8x both-sided
• Size (L x W x H): 596.5 x 144 x 30 mm (+/- 3%)
• Thickness: 30 mm
• Ports: 5x G1/4 (1x fill/drain port included)
• Material: copper fins, pre-chambers and channels, brass threads, stainless steel outer housing

The NexXxoS Full Copper series

Alphacool says it has dominated the market with the NexXxoS Full Copper radiator series for more than a decade. In its words: "Our extensive portfolio of radiator variants is unique in the world." Just like its manufacturing process, it adds, "which allows us to produce" every water-carrying part and the fins out of copper. As a result, Alphacool claims, the series offers the highest thermal conductivity of any radiator on the market. Thanks to their exceptional performance, it says, 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: HPE

The 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: this one has 16 cooling channels and 18 fins per inch. Thus a larger volume of water is in direct contact with the fins, and Alphacool says the heat transfer is enormously improved. According to Alphacool, the higher number of fin rows and their shortening also makes much more efficient use of the cooling surface. The data sheet puts it at 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.

What the loop needs

A loop runs in through one IN/OUT port and out through another, so the radiator takes two G1/4 fittings, with a thread length of 5 mm at most. It holds four 140 mm fans on one side or eight with both sides fitted, on M3 threads. All screws for mounting in the case and for mounting the fans are included with the radiator: 16x M3x5 for the case and 16x M3x30 for the fans. Additional screws are not usually required.

Notes

• Use only clear, transparent water cooling fluids. Alphacool warns that the particles and additives in pastel liquids can clog and permanently damage water cooling products such as radiators, pumps, coolers and hoses, which can result in voiding the manufacturer's warranty as well.
