New DeltaMate GPU Block Expands Cooling Options for High-End Graphics Card Owners

Thermal Grizzly has announced the release of a new DeltaMate GPU Block designed specifically for the MSI RTX 5090 Suprim, giving enthusiasts and professionals another premium cooling solution for one of the most powerful consumer graphics cards on the market. The block became available this month at a price of 549.90 euros, marking an important addition to Thermal Grizzly’s growing portfolio of custom liquid cooling products.

The significance of this release lies in the fact that custom factory variants like the MSI Suprim and Asus ROG models feature their own proprietary PCB designs. Unlike reference versions, these customized boards cannot use standard water blocks, requiring manufacturers to develop model-specific solutions. For owners of the MSI Suprim RTX 5090, this new block eliminates the barrier that previously forced them to choose between air cooling or seeking third-party solutions that might not offer optimal thermal performance.

The DeltaMate block incorporates several features that address the cooling challenges posed by the RTX 5090’s substantial power consumption and heat output. The core cooling element uses a dual-coldplate design made from high-quality copper, which actively manages heat from the GPU core, memory modules, and voltage regulator modules. This multi-target approach ensures that no component becomes a thermal bottleneck during intensive gaming or professional workloads.

The microfin structure measures just 0.2mm in width, creating an extremely dense heat exchange surface that maximizes contact with your coolant. This ultra-high-performance design translates to lower water temperatures and more stable GPU boost clocks during peak usage. The block also features optimized flow pathways that balance cooling efficiency with manageable pump requirements, preventing unnecessary wear on your loop’s circulation system.

Build quality is emphasized throughout the design, with black anodized aluminum housing providing durability and aesthetics. An RGB-illuminated borosilicate glass viewing window not only looks professional in case setups but also allows users to monitor coolant clarity and fluid levels at a glance. For shoppers considering a custom loop, the cooling performance becomes increasingly important as GPUs gain additional capabilities beyond traditional gaming.

What Comes in the Box and Compatibility Details

Thermal Grizzly includes essential thermal management materials with the block: thermal paste, thermal pads, and thermal putty. These components ensure proper contact between the block’s cooling surfaces and the GPU while helping seal the unit against coolant leaks. The modular design incorporates an optional 4-port Through Terminal, giving builders flexibility in how they integrate the block into larger custom loop systems.

It is worth noting that Thermal Grizzly already offers a specialized water block for the Asus ROG RTX 5090 Astral, demonstrating the company’s commitment to supporting premium custom variants. The expansion to include the MSI Suprim version signals strong demand among enthusiasts who invest in high-end graphics cards and are willing to implement sophisticated cooling solutions. For those tracking the broader GPU market, professional-grade GPU releases continue reshaping how consumers view cooling and thermal management.

The 549.90 euro price point reflects the premium engineering and materials involved. This block targets a specific audience: MSI RTX 5090 Suprim owners who either demand the lowest possible operating temperatures for sustained overclocking, require stable thermal profiles for professional rendering and AI workloads, or simply prefer the flexibility and customization of a liquid-cooled system. For casual gaming at standard settings, the Suprim’s bundled air cooling solution performs adequately, but serious enthusiasts will appreciate the thermal headroom this block provides.

Custom liquid cooling also offers intangible benefits, including quieter operation at load, improved case aesthetics, and the ability to cool multiple components through a single integrated loop. As GPU capabilities expand into areas like local AI inference, maintaining optimal thermals becomes even more valuable. GPU cooling standards continue evolving as workloads diversify, making premium blocks increasingly relevant.

Key Takeaway for Shoppers

If you own an MSI RTX 5090 Suprim and have been considering a move to custom liquid cooling, this block removes a major obstacle by offering a professionally engineered solution tailored to your specific card’s layout and power delivery. The inclusion of all necessary thermal interface materials simplifies installation, though builders should have basic loop assembly experience before attempting the upgrade. With shipping commencing this month, availability should stabilize quickly across European retailers.
