Alphacool NexXxoS HPE-20 Full Copper 280mm x 20mm Radiator

For over a decade, Alphacool has dominated the market with its NexXxoS Full Copper radiator series. The extensive portfolio of radiator variants is unique worldwide, as is our manufacturing process, which allows us to produce all water-bearing components and cooling fins from pure copper. This gives the NexXxoS series the highest thermal conductivity of any radiator on the market. With their unparalleled performance, these radiators effortlessly dissipate even extremely high heat output and are indispensable in many areas of the cooling industry.

The next evolutionary step: the NexXxoS HPE Full Copper Radiator!
The NexXxoS Full Copper HPE Radiator uses the same materials as previous NexXxoS models but takes a technical leap forward. The denser 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. Furthermore, the increased number of fin rows and their shorter length allow for much more efficient use of the cooling surface. Comparative 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 difference compared to the standard NexXxos radiators increases progressively, reaching a potential performance increase of up to 6K.

Space-saving & flexible installation:
Thanks to their low profile of only 20mm, the compact slim radiators can be installed very flexibly, even in the tightest cases.

Connection options & mounting:
The NexXxos HPE radiator features one IN and one OUT port with G1/4" threads on each of the end chambers. All necessary screws for mounting in the case and for attaching the fans are included. Additional screws are generally not required.

Warranty: 10 years
