Alphacool ES RTX A4000 with Backplate

The Alphacool ES Copper/Carbon water cooler with backplate has been specially designed for the Alphacool Enterprise Series. The positioning of the connections significantly simplifies the hose routing of the cooler in the server rack. The top of the cooler is made of carbon and makes the water cooler lighter compared to Alphacool's Eisblock with acetal or acrylic top. Thanks to its compact design, the cooler only requires 1 slot in the server rack instead of the previous 1.5 slots, which offers additional space savings and makes the use of the ES Copper/Carbon GPU water cooler even more attractive.

More performance!
Alphacool has managed to position the cooler as close as possible to the components to be cooled. For this purpose, the thermal pads used have been reduced to a thickness of 1mm. Since the water flow within the reduced thickness copper block has been optimized, all important components such as the GPU, voltage regulators, and VRAMs are cooled much more effectively.

Chrome-plated copper
The cooler is made entirely of chrome-plated copper. Chrome plating is harder than nickel plating and is therefore more resistant to acids, scratches, and damage. The chrome plating also looks more homogeneous and offers a gloss that cannot be achieved with nickel plating. Chrome-plated coolers have so far only been used in the industrial sector, where more extreme stresses are applied to the coolers.

Connections on the back?
To save space in width and height during installation, inputs and outputs have been positioned on the back of the cooling block. This connection position makes it easier to connect the GPU cooler to the water circuit and allows for easy hose routing even in tight server cases.

Copper or aluminum?
Alphacool exclusively uses copper or high-quality plastics for all water-carrying parts. Copper has an almost twice as high thermal conductivity as aluminum and is therefore the better choice for water cooling.

Thermal paste & thermal pads
The thermal paste included in the package is Alphacool's Subzero with a thermal conductivity of 16 W/mK. The non-conductive thermal grease is particularly suitable for high contact pressures and can be processed perfectly due to the viscosity of 850000 TF. Alphacool uses soft thermal pads that perfectly adapt to the components to be cooled and are very durable. The pads in thicknesses of 2mm and 3mm have a thermal conductivity of 3 W/mK. The 1mm thick pads can even dissipate 7 W/mK of heat.

Subtle appearance
The matte carbon finish gives the cooler an elegant appearance. This makes it also interesting for private users who want to do without aRGB lighting.
