Alphacool ES Geforce RTX 5090 Gaming Diseño 1-Slot (10292)

Transform your NVIDIA GeForce RTX 5090 into a single-slot powerhouse with the Alphacool ES Geforce RTX 5090 Gaming 1-Slot Design water block. Engineered for compact workstations, high-density server racks, and small form factor gaming rigs, this full-cover block cools the GPU, VRAM, and VRM with a nickel-plated copper cold plate and a precision microfin structure. The acrylic top showcases your coolant and digital RGB lighting, while the acetal terminal provides four G1/4" ports for flexible loop routing. Pressure-tested to 0.8 bar and CNC machined for a perfect fit, this block is the foundation of a silent, high-performance cooling solution.

Why choose it

The Alphacool ES block delivers exceptional thermal performance in a remarkably slim profile. By reducing your RTX 5090 to a single slot, you free up valuable space for additional expansion cards or improved airflow in tight builds. The nickel-plated copper cold plate ensures optimal heat transfer, while the microfin structure maximizes surface area for efficient cooling. The acrylic top not only looks stunning with RGB lighting but also allows you to monitor coolant flow and detect any potential issues at a glance. With a parallel flow design and low restriction, it integrates seamlessly into even the most complex loops.

Ideal use cases

• Compact gaming PCs where space is at a premium
• Workstations requiring multiple GPUs in a single chassis
• Server and rendering farms needing high-density compute
• Custom water cooling loops with aesthetic RGB setups
• Silent PC builds aiming for maximum cooling efficiency

Good to know

This block does not include a backplate; Alphacool offers compatible backplates separately for added rigidity and aesthetics. The 3-pin JST connector is compatible with most motherboard RGB headers or Alphacool's own controllers. Always use clear or low-particulate coolants to prevent clogging of the microfin structure. The block is pressure-tested to 0.8 bar, ensuring leak-free operation under typical loop pressures. With a 2-year warranty, you can trust in Alphacool's quality and support.
