Alphacool ES RTX 4000 Ada Gen. 1-Slot GPU-Køler (14596)

For professionals running NVIDIA RTX 4000 Ada Generation graphics cards in dense workstation or server environments, the Alphacool ES RTX 4000 Ada Gen. 1-Slot GPU-Cooler replaces the stock air cooler with a full-cover liquid cooling solution that reduces the card to a single PCIe slot. This frees up adjacent slots for additional accelerators, capture cards, or high-speed networking, while keeping GPU temperatures low under sustained rendering, AI inference, or simulation workloads.

Key specifications

• Full-cover water block for NVIDIA RTX 4000 Ada Generation professional GPUs
• 1-slot design after installation – ideal for multi-GPU and server builds
• Nickel-plated copper base plate with optimized micro-fin structure over the GPU core
• Acetal top and terminal for durability and low weight
• Four G1/4" connection threads for flexible tubing routing
• No integrated illumination – clean, professional appearance
• Thermal paste and thermal pads included; mounting screws provided
• Backplate not included – available separately for additional PCB cooling

Why choose it

Alphacool's Enterprise Solutions series is engineered for reliability in 24/7 operation. The nickel-plated copper base ensures excellent heat transfer and corrosion resistance, while the acetal top keeps the block lightweight and electrically non-conductive. The parallel flow design and fine micro-fin structure deliver low flow restriction and high cooling performance, even with modest pump speeds. By shrinking the card to a single slot, you can pack more computational power into each workstation or server chassis without thermal throttling.

Ideal use cases

• Multi-GPU workstations for rendering, AI training, or scientific computing
• Rack-mount servers with limited PCIe slot spacing
• Silent professional workstations where fan noise must be minimized
• Custom liquid cooling loops for enterprise or prosumer builds

Good to know

Installation requires draining and disassembling the original cooler, cleaning the GPU die, and applying the included thermal interface materials. The block is compatible with standard G1/4" fittings and works with any common coolant. For complete PCB coverage and improved rigidity, consider pairing it with the optional Alphacool ES backplate (sold separately). Always verify compatibility with your exact RTX 4000 Ada Generation card model before purchase.
