The Thermal Grizzly DeltaMate GPU Block for the ASUS ROG Astral RTX 5080 is a premium full-cover water block engineered to deliver exceptional cooling performance, premium materials, and an uncompromising installation experience. Designed specifically for compatible ROG Astral RTX 5080 graphics cards, the DeltaMate combines an innovative dual cold plate design with an ultra-high-performance microfin structure to maximize thermal efficiency across the GPU, VRAM, and VRM components.

At the heart of the DeltaMate is a massive dual copper cold plate assembly. The dedicated GPU core cold plate features an ultra-high-performance microfin design with an extremely fine 0.2mm fin width, 0.2mm channel width, and 2.5mm fin height. This precision-machined structure provides over 13,400mm² of cooling surface area, allowing coolant to efficiently remove heat from the GPU core under even the most demanding workloads.

A separate full-size copper cold plate cools the VRAM and power delivery components, weighing over 900 grams and precision-machined for optimal contact and heat transfer. Both cold plates are CNC machined, precision blasted, nickel plated, and never produced using the skiving process, ensuring exceptional manufacturing quality and long-term durability.

The black anodized aluminum housing incorporates a premium Schott BOROFLOAT® glass viewing window illuminated by 14 addressable RGB LEDs. Unlike acrylic, BOROFLOAT® glass offers superior scratch resistance, UV resistance, and chemical durability while producing a unique lighting effect thanks to its hand-polished edges.

The included brass Direct Terminal provides standard front-facing G1/4" inlet and outlet ports, while an optional Through Terminal is available separately for additional routing flexibility.

Installation is further simplified by the included "The Oracle" spacer PCB. This precision-matched installation template helps verify proper alignment before disassembly, identifies screw and thermal pad locations during installation, and even assists with reassembling the factory cooler if needed later.

To ensure maximum cooling performance, Thermal Grizzly includes everything needed for installation, including Duronaut thermal paste, Minus Pad Advance thermal pads, Putty Advance, application tools, mounting hardware, and hex keys.

Whether you're building a flagship gaming system or an extreme overclocking rig, the DeltaMate GPU Block delivers outstanding thermal performance, premium construction, and exceptional attention to detail.
