The Alphacool NexXxoS GPX Pro Backplate for the Alphacool GPX Pro Solo GPU cooler. The backplate serves to stabilize and evenly distribute the pressure. In conjunction with a suitable optional thermal pad, it can also prevent the bending of the PCB due to the rear pressure. Additionally, when used with an appropriate thermal pad, the cooling performance can be enhanced. This is supported by the fine cooling fins on the back of the backplate.
