The Alphacool ES RTX 4000 Ada Ge. GPU cooler was developed for the Enterprise Series, but not only impresses with its improved cooling performance and compact design, but also with its matte carbon look. Connections on the back? By using a thin and extremely stable carbon plate, this could be designed as a single slot cooler without having to make any compromises on the copper block. In combination with the connections placed at the back, several coolers can be easily stacked on top of each other. Copper or aluminum? High-quality copper is used for all water-carrying parts, which offers almost twice the thermal conductivity compared to aluminum. In addition, the copper is chrome-plated instead of nickel-plated, which provides additional protection for the cooler. The chrome plating is more resistant to acids, scratches and other damage, effectively preventing coatings from chipping off. Thermal paste & thermal pads Included in delivery is the Apex thermal paste, which, with its low silicone content, is the most durable thermal paste that Alphacool offers. This electrically non-conductive paste is ideal for high contact pressures and is easy to work with thanks to its viscosity. Soft, high-performance thermal pads are also supplied, which adapt perfectly to the components to be cooled.
