The DeltaMate GPU Block Astral - ROG 5080 marks a step forward in both performance and aesthetics for high-end GPU cooling. Thermal Grizzly’s latest addition replaces traditional acrylic with Schott BOROFLOAT glass, offering superior light refraction that enhances the visual appeal of integrated RGB lighting while also resisting alcohol-based cleaners better than standard materials.
This isn’t just a cosmetic upgrade; the block retains all the performance characteristics of its predecessors. It features ultra-high-performance microfins with a 0.2 mm structure width, ensuring efficient heat dissipation. The design splits cooling duties between two coldplates: one for the GPU core and another for VRAM and voltage regulators (VRM), both milled from high-quality copper and precision-blasted for optimal thermal transfer.
Key Specifications
- Ultra-High-Performance microfins with 0.2 mm structure width
- Full-metal construction with RGB-illuminated Schott BOROFLOAT glass viewing window
- Dual coldplate design for targeted GPU, VRAM, and VRM cooling
- Configurable with Through Terminal (4-port) or Direct Terminal (2-port) brass connectors
- Includes thermal paste, pads, and putty
The block is compatible with a range of ROG Astral RTX 5080 models, including variants with 16 GB GDDR7 memory. Its cooling performance hinges on an optimized coolant flow path across the copper baseplates, which are nickel-plated after precision machining to ensure longevity and thermal efficiency.
Market Impact
This partnership between Thermal Grizzly and ASUS ROG targets PC builders who prioritize both performance and visual appeal. The use of BOROFLOAT glass addresses practical concerns—such as cleaner resistance—while the dual coldplate design ensures that high-power GPUs like the RTX 5080 operate at peak efficiency, reducing thermal throttling in demanding workloads. For enterprise users running AI or rendering tasks, this could translate to more stable performance and lower operational costs over time.
While the block is tailored for ROG Astral models, its underlying engineering—such as the 13,440 mm² surface area on the core coldplate—sets a benchmark for high-end GPU cooling. The absence of skiving in favor of full CNC milling further underscores its precision, though it remains to be seen how widely this approach will be adopted beyond ASUS’s ecosystem.
For now, the DeltaMate GPU Block Astral - ROG 5080 positions itself as a premium option for enthusiasts and professionals who demand both cutting-edge cooling and a refined aesthetic. Its durability and performance metrics suggest it could become a standard reference in high-end GPU cooling, but its niche focus on specific models may limit broader market penetration.
