The next generation - the Alphacool
Eisblock Aurora water cooler for Geforce RTX 4XXX graphics cards. In
order to dissipate the enormous heat of this graphics card generation in
the best possible way, numerous optimizations have been made to the
water cooler compared to the previous model. The fin structure was
adapted and enables a very good water flow while increasing the cooling
surface. The modified jet plate with improved inflow engine ensures an
optimal distribution of the water on the cooling fins.
Important
note: The RTX 4090 Eisblock Aurora Reference cooler is not compatible
with Nvidia's Geforce RTX 4090 Founders Edition. The RTX 4090 FE is
compatible with the following cooler: Alphacool Eisblock Aurora Acryl
GPX-N RTX 4090 Founders Edition with Backplate (Art. 13456)
Technical Highlights
The
fin structure of this Eisblock cooler generation 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 increasing the cooling surface. The jet plate has a revised inlay
that spreads the water pressure better over the fins thus optimizing the
heat absorption. The adjusted water inflow gives the water a better
angle of inflow.
Chrome-plated copper
The cooler is
made entirely of chrome-plated copper. A chrome plating is much harder
than a nickel plating and therefore less sensitive to acids, scratches
and damage. It completely eliminates the risk of chipping nickel
plating. Additionally, chrome plating looks much more homogeneous and
provides a shine that cannot be achieved by nickel plating.
Chrome-plated coolers have previously only been used in the industrial
sector in areas where extreme influences act on the coolers.
Design
The
Aurora design of the Geforce RTX 4XXX Eisblock generation is visually
calmer and simpler. Only one O-ring runs around the entire cooler. The
design around the cooling fins and jetplate makes for a cleaner look.
The illumination of the digitally addressable RGB LEDs is even better
distributed throughout the cooler as a result of the chrome plating. The
terminal's design is in line with 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 highest performing thermal
pastes on the market. The electrically non-conductive thermal compund is
particularly well suited for high contact pressures, but can still be
processed perfectly due to its viscosity of 850,000 TF. Alphacool Soft
Pads with 1mm thickness are used on the voltage converter and the
graphics memory. The thermal conductivity of the pads is 7W/mk. The pads
for the back of the PCB are 3mm thick and have a thermal conductivity
of 3W/mk.
