Details
The Alphacool ES NV A100 80GB PCIe is a GPU water block for the PNY NVIDIA A100 with 80GB HBM2e (TCSA100M-80GB-PB / 900-21001-0020-100). It is a 1-slot cooler for the server rack with both G1/4 connections on the back, and the black aluminum backplate is in the box.

Compatibility
Alphacool lists this card for this block:
- PNY NVIDIA A100, 80GB HBM2e (TCSA100M-80GB-PB / 900-21001-0020-100)
The block was designed for one PCB layout, and graphics card manufacturers occasionally revise a card so that a cooler no longer fits later models. Before ordering, compare your card and its PCB number with the pictures in Alphacool's GPU configurator. Alphacool also publishes a Compatibility List for Nvidia cards.
One slot in the rack
Alphacool specially developed its ES Copper/Carbon water cooler with backplate for the Alphacool Enterprise Series. Thanks to the compact design, the cooler only needs 1 slot in the server rack instead of the previous 1.5 slots. Alphacool sees these additional space savings as one more argument that makes the use of this graphics card water cooler even more attractive. The cooler top is made of carbon, which makes the block lighter compared to Alphacool's Eisblocks (ice blocks) with acetal or acrylic tops.
Connections on the back?
In order to save space in width and height when installing, the water inputs and outputs were moved and positioned on the back of the cooling block. Alphacool says this positioning of the connections significantly simplifies the tubing, or hosing, in a rack. This connection position also facilitates the integration of the GPU cooler into the water circuit and enables easy tubing even in the tightest, most narrow server housings.
More efficient, more performance
Alphacool has managed to position the cooler as close as possible to the components to be cooled. For this purpose the heat conducting thermal pads used were reduced to a thickness of 1mm, and the copper block got the maximum possible reduction in thickness. The water flow within this reduced-thickness block has been optimized. Since then, Alphacool says, all important components such as the GPU, the voltage converters and the VRAMs are cooled by water much better and more effectively. In its words, all of this provides a significant increase in cooling performance.
Chrome-plated copper
The cooler is made entirely of chrome-plated (chromed) copper. Alphacool says chrome plating is much harder than nickel plating and therefore more resistant, or less sensitive, to acids, scratches and damage. In its words it completely eliminates the risk of chipping that nickel plating carries. Alphacool also finds that chrome looks more homogeneous and offers a shine that cannot be achieved with nickel. It adds that chrome-plated coolers have so far only been used in the industrial sector, in areas where extreme influences and loads act on the cooler.
Copper or aluminum?
For all water-bearing parts Alphacool uses only copper, and its earlier text for this block says copper or high-quality plastics for all water-carrying parts. Its reason is that copper has almost twice the thermal conductivity of aluminum, making it for Alphacool clearly the better choice of material for water cooling. It describes the chrome-plated base as highly resistant to acid, which means, for Alphacool, that chipping of the chrome can be ruled out.
Thermal compound & thermal pads
The included thermal paste, or thermal compound, is Alphacool's Subzero with a thermal conductivity of 16 W/mK. The Thermal Grease is electrically non-conductive and particularly suitable for high contact pressures. Alphacool says it can still be applied and processed perfectly thanks to its viscosity of 850,000 TF. The thermal pads are soft, so they adapt and fit perfectly to the components, and Alphacool calls them very durable. Its text gives 3 W/mK for the 2mm and 3mm thick pads, and says the 1mm thick pads can even dissipate 7 W/mK of heat.
Discreet appearance
Alphacool says the matte carbon finish gives the cooler a noble, elegant appearance. For Alphacool that makes it additionally interesting for private users who want to do without aRGB lighting.
What the loop needs
The block has two G1/4 threads, both on the back. Each takes one of the compression fittings for your tube size, which are not in the box. Thermal pads, thermal grease, a putty tool, the PCIe bracket and three sets of screws come with the block.

Notes
- Alphacool asks that the block be used only with clear transparent water cooling fluids. It warns that the particles and additives in Pastel liquids can clog and permanently damage radiators, pumps, coolers and hoses, and that this can void the manufacturer's warranty.
- Remove the original cooler on an antistatic mat, taking extreme care if it is held with thermal glue. Clean the card of thermal paste and pad residues with a solvent such as isopropanol alcohol before fitting the block.
- The GPU bracket that holds the card on the block is the one from the original graphics card manufacturer.
