Product Overview
Image of the Alphacool NexXxoS HPE-45 Full Copper 120mm Radiator. The radiator is predominantly black, featuring a dense array of fins for heat dissipation. It has a rectangular form factor designed for a 120mm fan. Visible on the top surface are the 'HPE' and 'alphacool' logos. The side profile shows the integrated G1/4" ports for water connections.
For over a decade, Alphacool has been a leader in the market with its NexXxoS Full Copper radiator series. This series is unique globally due to its manufacturing process, which utilizes pure copper for all water-carrying parts and cooling fins. The NexXxoS series delivers the highest thermal conductivity available, enabling radiators to effectively dissipate extreme waste heat, making them crucial in various cooling industry applications.
Key Features:
- ? 1.2x increased water throughput compared to NexXxos standard
- ? 20% more efficient heat transfer compared to NexXxos standard
- ? 100% of the internal structure is made of copper
Technical Evolution: NexXxoS HPE Full Copper Radiator
The NexXxoS Full Copper HPE Radiator builds upon previous NexXxos models with enhanced technical capabilities. Its condensed internal structure allows for more water channels and copper fins, leading to a larger volume of water in direct contact with the cooling fins and significantly improved heat transfer. The increased fin density and optimized fin length maximize the efficiency of the cooling surface. Comparative tests indicate a performance increase of up to 4.5K over conventional NexXxos radiators, with potential gains reaching up to 6K at higher ambient temperatures and fan speeds.
Test Setup Example: NexXxos ST30 360mm radiator vs. NexXxos HPE-30 360mm radiator with Eisbaer cooler, 3x 120mm Rise Aurora fans, and an Asus Prime x299 motherboard with an Intel i9 10900x CPU (350W waste heat).
Connection Options & Mounting
The NexXxoS HPE radiator features two G1/4" IN/OUT connections located in the pre-chamber area. An additional G1/4" port on the opposite side serves as a fill or drain port for the water circuit. All necessary screws for case mounting and fan installation are included with the radiator; no additional screws are typically required.
Safety Features
Safety First: The radiator is equipped with special protective plates beneath all mounting holes. These plates prevent screws from being overtightened, safeguarding the cooling fins and internal water channels from damage.
Patented Screw Plugs: Alphacool's patented screw plugs are fully recessed into the radiator surface. This design ensures flush mounting and simplifies installation within the PC case, avoiding issues with protruding plugs.
