Thermal Grizzly DeltaMate Glass water block for RTX 5090 hits $643

Thermal Grizzly released the Glass Edition of its DeltaMate GPU water block, a targeted update for owners of the ASUS ROG Astral GeForce RTX 5090. This release matters because it upgrades the viewing window material from standard acrylic to high-end glass, addressing a common preference among enthusiasts who want better clarity and durability in their custom loops. Buyers with compatible cards can now choose a more premium aesthetic without switching to a completely different cooling solution.

Schott glass window and full-metal housing upgrade the RTX 5090 cooling experience

The new block is designed specifically for the ASUS ROG Astral RTX 5090 lineup. It supports all four variants of that graphics card, including the Standard, OC, White, and Liquid Cooled versions. This broad compatibility ensures that users do not need to hunt for a different block if they own a specific variant of the high-end GPU.

Specifications

• Compatibility: ASUS ROG Astral GeForce RTX 5090 (Standard, OC, White, LC)
• Material: Black anodized aluminum housing, Schott BOROFLOAT glass viewing window
• Coldplate Design: 0.2 mm slots and 0.2 mm fins
• Cooling Sections: Separate copper section for VRAM and VRM
• Fittings: Brass two-port Direct Terminal (standard), optional four-port Through Terminal

The most significant physical change is the replacement of the previous PMMA acrylic viewing window with a Schott BOROFLOAT glass panel. The entire unit features a full-metal construction with a black anodized aluminum housing. Inside, the GPU coldplate uses 0.2 mm slots and 0.2 mm fins to maximize surface area for heat transfer. A separate copper section cools the VRAM and VRM components independently.

Thermal Grizzly includes an RGB lighting system within the black anodized aluminum housing to match the aesthetic of modern high-end GPUs. The block ships with a brass two-port Direct Terminal fitting as the standard configuration. Users who require more hose connections can purchase an optional four-port Through Terminal fitting separately. This modular approach allows builders to tailor the plumbing to their specific loop size and layout.

The DeltaMate Glass Edition is priced at 643.38 USD (around $643). It is available globally through Thermal Grizzly's distribution channels. We touched on Thermal Grizzly DeltaMate MPII CPU Block in our earlier Thermal grizzly coverage, showing the vendor's expanding range of water cooling solutions for both CPUs and GPUs.

Thermal Grizzly has released the Glass Edition to provide a more durable and visually appealing option for the ROG Astral RTX 5090. The upgrade to Schott BOROFLOAT glass and the retention of full-metal construction define this new variant. The product is confirmed to support all major variants of the target graphics card at a fixed price point.
