The next generation - The Alphacool Eisblock Aurora water cooler for Geforce RTX 4XXX graphics cards. In order to dissipate the enormous waste heat of this graphics card generation in the best possible way, numerous optimizations were carried out on the water cooler compared to the previous model. The fin structure has been adapted and enables very good water flow while at the same time increasing the cooling surface. The modified nozzle plate with improved inflow engine ensures optimal water distribution on the cooling fins.

Technical highlights
The fin structure of this generation of ice block coolers was developed together with Nvidia board partners. The fin thickness is 0.4 mm, the distance between the cooling fins is 0.4 mm. This ensures a very good water flow while at the same time increasing the possible cooling surface. The jet plate has a revised inlay that distributes the water pressure better to the fins and optimizes heat absorption. The adjusted water flow helps the water to achieve a better inflow angle.

Chromed copper
The radiator is made entirely of chrome-plated copper. Chrome plating is much harder than nickel plating and therefore less sensitive to acids, scratches and damage. This completely eliminates the risk of nickel plating flaking off. In addition, chrome plating looks much more homogeneous and offers a shine that cannot be achieved with nickel plating. So far, chrome-plated coolers have only been used in the industrial sector in areas where the coolers are subject to extreme influences.

The Aurora design of the Geforce RTX 4XXX Eisblock generation is visually calmer and simpler. Only one O-ring goes around the entire cooler. The construction around the cooling fins and the jetplate ensures a clearer look. The lighting of the digitally addressable RGB LEDs is even better distributed in the cooler thanks to the chrome plating. The shape of the terminal corresponds to the classic Aurora design.

Thermal paste & thermal pads
The included thermal compound is Alphacool's Subzero. With a thermal conductivity of 16 W/mK, it is one of the most powerful thermal paste on the market. The electrically non-conductive Thermal Grease is particularly well suited for high contact pressures, but can still be processed perfectly thanks to its viscosity of 850,000 TF. Alphacool soft pads with a thickness of 1mm are used on the voltage converters and the graphics memory. The thermal conductivity of the pads is 7 W/mK. The pads for the back of the PCB are 3mm thick and have a thermal conductivity of 3 W/mK.
