Compatibility

Alphacool lists these cards for this block:

• PNY RTX A4000, 16GB GDDR6, 4x DP (VCNRTXA4000-PB)
• PNY RTX A4000, 16GB GDDR6, 4x DP, Smallbox (VCNRTXA4000-SB)

The cooler was designed for one PCB layout, and card makers sometimes revise a board 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, or look it up in its Compatibility List for Nvidia cards.

One slot in the server rack

This ES Copper/Carbon water cooler with backplate was specially developed for the Alphacool Enterprise Series. The cooler top is made of carbon, which makes the water cooler lighter compared to Alphacool's Eisblocks (ice blocks) with acetal or acrylic tops. Thanks to the compact design, the cooler only needs 1 slot in the server rack instead of the previous 1.5 slots. Alphacool says this offers additional space savings and makes the use of the GPU water cooler, a graphics card block, even more attractive.

What the loop needs

The cooler 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. Alphacool gives 60 °C as the maximum operating temperature. There is no lighting to connect. The backplate, the thermal pads, the thermal compound, a putty tool and the screws come with the cooler.

Notes

• Alphacool asks that the cooler 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 and clean the card of thermal paste and pad residues before fitting the cooler. During assembly, make sure taller parts have enough space around them.
