Alphacool NexXxoS HPE-30 Full Copper 140mm Radiator

Quick Info

For over a decade, Alphacool has led the market with its NexXxoS Full Copper radiator series, offering a unique portfolio of radiator variants globally. This is achieved through a manufacturing process that utilizes pure copper for all water-carrying parts and cooling fins. Consequently, the NexXxoS series boasts the highest thermal conductivity available for radiators. Their exceptional performance allows for the dissipation of extremely high waste heat, making them indispensable in various cooling industry sectors.

• 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

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 utilizes the same materials as previous NexXxos models but advances the technology. The condensed internal structure allows for an increased number of water channels and copper fins. This results in a larger volume of water in direct contact with the cooling fins, significantly improving heat transfer. The increased number of fin rows and their shortening also optimizes the use of the cooling surface. Comparison tests* with conventional NexXxos radiators have demonstrated a performance increase of 4.5K when using the HPE radiator. At higher ambient temperatures and higher fan speeds, the performance gap with normal NexXxoS radiators increases progressively, potentially reaching a performance increase of up to 6K.

Connection options & mounting

The NexXxoS HPE radiator features two IN or OUT connections with G1/4" threads in the pre-chamber area. The opposite side includes a fill or drain port for filling and draining the water circuit. All necessary screws for mounting in the case and for fan attachment are included with the radiator. Additional screws are typically not required.

Safety first

The NexXxoS HPE radiator is equipped with special protective plates beneath all mounting holes. These plates prevent screws from being overtightened, thereby protecting the cooling fins and underlying water channels from damage.

Patented screw plugs

All NexXxoS HPE radiators incorporate Alphacool's patented screw plugs. These recessed screw plugs ensure a flush surface, preventing protrusions that could hinder flush case installation. This design allows for easy installation within the PC case.
