Full copper
Alphacool describes itself as the only manufacturer worldwide that uses only copper for all water-carrying components in the radiator, and as uncompromising in its choice of materials. The chambers, the cooling fins and the cooling channels are made of pure copper. Other materials are found in two places only: the connection threads are made of brass and the outer housing of steel. Alphacool's text calls the housing sheet steel, while its technical data lists stainless steel. Alphacool gives the reason for the copper as its high thermal conductivity of 400 W/mK (by comparison: aluminum has 236 W/mK), chosen to maximize the radiator's performance.
What is new in the HPE version
The HPE radiators are based on Alphacool's NexXxoS series. But what's new? This version features additional cooling channels and a very high fin density. Due to its technical design, Alphacool says, cooling performance is significantly increased without restricting water flow within the radiator. When fans are mounted on both sides in push/pull configuration, Alphacool says a noticeable drop in water temperature can be achieved compared to standard radiators. The fin density has a spacing of 15 FPI, which Alphacool says allows for optimal airflow. All cooling fins are also equipped with small flaps: tiny wings that guide the airflow in the desired direction and create controlled turbulence. According to Alphacool this increases cooling performance and reduces potential flow noise.
Built for 5 Bar
Alphacool designed these radiators specifically for industrial and server environments. Thanks to thicker cooling channels and reinforced welds, they are built to withstand operating pressures of up to 5 Bar. Alphacool sees this as ensuring maximum reliability in demanding industrial use.
X-Flow
In traditional PC radiators the water flows in a U-shape, meaning the inlet and outlet are on the same side. Alphacool notes that this has certain advantages in typical PC setups. However, creating a proper water loop in an extremely flat server is difficult this way. With X-Flow technology the inlet and outlet of this radiator are on opposite sides. That makes it easy to implement a circular water flow in a server rack. The water runs in a circle: exiting one side directly into a CPU, possibly then through one or more graphics cards, and returning on the other side to the radiator.
What the loop needs
In the area of the pre-chambers, each side features three IN or OUT ports with G1/4 threads, six in all. Two are used, one per side, so the radiator takes two fittings, and the other four take the 4x plugs in the box. Thread length in the ports is 5 mm at most. All NexXxoS HPE X-Flow radiators use Alphacool's patented sealing plugs. Anyone who has ever mounted a radiator to the front or top of a case knows the problem: protruding sealing plugs can prevent the radiator from sitting flush. With these plugs Alphacool considers the issue solved, because they are completely recessed and sit flush with the surface of the radiator. This ensures a clean installation. Alphacool adds that, of course, the radiators also look significantly more refined with these flat plugs.
The radiator takes three 80 mm fans on one side or six on both, on M3 threads. All screws required for mounting the radiator in a case and for attaching the fans are included: 12x M3x28 and 12x M3. Additional screws are usually not necessary. A special protective feature ensures that fan or mounting screws cannot be driven in too deeply. Protective plates have been placed beneath all mounting holes to prevent over-tightening, which protects the cooling fins and water channels underneath from damage.

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.
