## Description

Alphacool introduces its new series of graphics card water coolers for the latest Nvidia GeForce RTX generation. Part of the Core product series, these coolers combine the highest quality with exceptional performance. Thanks to an optimized technical design, these GPU coolers deliver outstanding cooling performance. At the heart of the cooler is a copper block, precisely milled from a single piece and complemented by a precisely crafted brass terminal with a nylon cover. A chrome finish enhances the copper cooler's durability and provides a smoother, more radiant surface than traditional nickel plating. The GPU water cooler has been completely overhauled technically. To optimize cooling performance, the distances between the cooler and the components of the PCB were redefined and tested. The water flow was simulated using the most advanced software and verified through practical tests.
