Water block + Backplate Aquatuning GmbH 13395 Αλουμίνιο Carbon Copper 1/4 ίντσες

The Alphacool ES GPX Copper/Carbon water cooler with backplate is part of the Alphacool Enterprise Series and is designed for efficient GPU cooling in dense server and workstation installations. The cooler features a carbon top to reduce weight, a chrome-plated copper cold plate and integrated backplate. The connector ports are positioned at the rear of the block to simplify tubing in tight racks. Its compact design requires only a single PCI slot for installation, saving space compared with earlier models.

Advantages

The chrome-plated copper construction provides improved durability and corrosion resistance compared with standard nickel plating, while chrome offers a more homogeneous finish. Reduced thickness of thermal pads (1 mm) and a minimized copper block combined with optimized internal water flow enable closer contact to GPU, voltage regulation components and VRAM, increasing cooling performance. A carbon top lowers overall weight and the rear-facing connections simplify hose routing in server housings.

Suitable for

• High-density server and rack-mounted workstations where space is limited
• GPU water-cooling loops requiring a single-slot cooling solution
• Systems that benefit from durable, chrome-plated copper cold plates
• Applications demanding efficient cooling of GPU, VRAM and voltage regulators

How to use

Mount the cooler to the GPU following the manufacturer’s mounting instructions, ensuring the thermal pads and supplied Alphacool Subzero paste are applied to the designated components. Connect the inlet and outlet hoses to the rear-facing G1/4" ports and integrate the block into the existing water-cooling loop. Verify that the block is secured in the single-slot position and that tubing routing maintains proper flow and clearance inside the rack or case.

Recommendations

Use corrosion-inhibiting coolant and follow standard water-cooling maintenance: flush the loop before installation, check for leaks after filling, and perform periodic coolant replacement. The chrome-plated copper surface is highly resistant, but recommended maintenance ensures long-term performance and reliability.
