Alphacool ES Geforce RTX 4090 Reference Design GPU Water Block with Backplate

The Alphacool ES Copper/Carbon water cooler with backplate was developed for the Alphacool Enterprise Series. Due to the positioning of the connections, the hosing of the cooler in the server rack is significantly simplified. The top of the cooler is made of carbon. This makes the water cooler lighter compared to Alphacool's Eisblocks with acetal or acrylic tops. This cooler is not 1 slot compatible! Important note: The RTX 4090 ES Reference cooler is not compatible with Nvidia's Geforce RTX 4090 Founders Edition. 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. Compatibility: Attention: unfortunately Inno3D is using two different PCB Layouts. Please check your serial number. If it looks like following, it is not compatible with our water blocks: 32-879-xxxx8xxxx - Inno3D GeForce RTX 4090 iCHILL Black, 24GB GDDR6X (C4090-246XX-18330005) - Inno3D GeForce RTX 4090 iCHILL Frostbite, 24GB GDDR6X (C4090-246XX-1833FB) - Inno3D GeForce RTX 4090 iCHILL X3, 24GB GDDR6X (C40903-246XX-1833VA47) - Inno3D GeForce RTX 4090 X3 OC, 24GB GDDR6X (N40903-246XX-18332989) - KFA2 GeForce RTX 4090 SG (1-Click OC), 24GB GDDR6X (49NXM5MD6DSK) Technical data cooler L x W x H: 209 x 120 x 24mm Material cooler: Chome-plated copper Material cooler top: carbon Threads: 2 x G1/4" Maximum working temperature: 60 degrees C Model: 13395
