The Alphacool ES GPX Copper/Carbon water cooler with backplate was specially developed for the Alphacool Enterprise Series. Due to the positioning of the connections, the tubing of the cooler in the server rack is significantly simplified. The cooler top is made of carbon. This makes the water cooler lighter compared to Alphacool's ice blocks with acetal or acrylic tops. Thanks to the compact design, only 1 slot is required for mounting the cooler in the server rack instead of the previous 1.5 slots. This additional space saving is one more argument for using the ES GPX Copper/Carbon graphics card water cooler.

More performance!
Alphacool manages to position the cooler in the best possible way close to the components to be cooled. For this purpose, the thermal pads used are reduced to a thickness of 1mm. The maximum possible reduction in the thickness of the copper block and the optimization of the water flow within the cooler allow all important components such as GPU, voltage converters and VRAMs to be cooled much better and more effectively by the water. All this ensures a significant increase in cooling capacity.

Connections on the back?
In order to save space in terms of width and height during installation, the inlet and outlet have been relocated to the rear of the cooling block. This positioning of the connections makes the tubing much easier and thus enables the GPU cooler to be easily integrated into the water circuit even in the narrowest of server housings.

copper or aluminum?
Alphacool only uses copper for all water-carrying parts. Copper has almost twice the thermal conductivity of aluminum and is therefore the significantly better choice of material for water cooling. The nickel-plated copper base is highly acid-resistant, which means that the nickel plating cannot flake off.

Thermal paste & thermal pads
The included thermal compound is Alphacool's Subzero with a thermal conductivity of 16 W/mk. 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. For the thermal pads, Alphacool uses soft pads that nestle perfectly against the components to be cooled and are very durable. The 2mm and 3mm thick pads have a thermal conductivity of 3 W/mk. The 1mm thick pads can dissipate 7 W/mk of heat.

Discreet appearance
The matt carbon finish gives the cooler a noble appearance. This also makes it interesting for private users who want to do without aRGB lighting.
