New NexXxos HPE ST-20mm Slim Radiator!


Staff member
Alphacool's NexXxoS HPE radiator is now also available as ST20 variant. The compact slim radiator can be mounted very flexibly and space-saving even in the tightest cases due to its low height of only 20mm.

Technically and functionally, the NexXxos HPE ST20 is comparable to the HPE-30 and HPE-45 versions. All water-bearing parts and the cooling fins are still made of pure copper. The number of water channels and copper fins inside the radiator has been increased with the result that a larger volume of water is now in direct contact with the cooling fins and the cooling surface is used much more efficiently. Thanks to the technical innovations, the heat transfer has been improved enormously compared to the previous NexXxos models and the cooling performance has been increased significantly.

The NexXxoS HPE ST-20 radiator is offered in the common variants (120/140/240/280/360mm) for 120mm and 140mm fans.
