Thermal Grizzly powers the RTX 5090 with DeltaMate

Mason Carter 09/17/2026

The world of high-performance graphics cards, particularly the ambitious RTX 5090, demands more than just powerful silicon—it demands sophisticated thermal management. For enthusiasts pushing the boundaries of gaming and professional rendering, the quest for ultimate performance often leads down the rabbit hole of custom liquid cooling.

Thermal Grizzly has long been a pioneer in this thermal revolution, having introduced its initial line of custom liquid cooling products, including the first water block designed for the RTX 5090. Now, as the market for bespoke hardware explodes, the company is stepping up the game with a new offering designed to cater to the most demanding setups.

This month, Thermal Grizzly is expanding its portfolio with the new DeltaMate GPU Block, specifically engineered for the MSI RTX 5090 Suprim. This addition opens up a new avenue for users of these exclusive custom variants who wish to integrate the superior efficiency of liquid cooling directly into their system.

Why is this expansion so exciting? Custom variants, such as the Asus ROG Astral or the MSI Suprim, are built with unique PCBs, necessitating a unique and bespoke GPU block design to manage heat effectively. The new DeltaMate GPU Block Suprim makes the transition to custom liquid cooling seamless for owners of the RTX 5090 Suprim.

The engineering behind the DeltaMate GPU Block Suprim is where the real magic happens. It is not just another piece of hardware; it is a finely tuned thermal solution:

It features ultra-high-performance microfins with a structure width of 0.2 mm, maximizing surface area for heat transfer.
The design utilizes full-metal construction, housed in a black anodized aluminum casing with an RGB-illuminated borosilicate glass viewing window.
A dual-coldplate system crafted from high-quality copper targets the GPU, VRAM, and VRM with precision.
The entire assembly boasts an optimized flow design, ensuring heat dissipation is handled with maximum efficiency.
All critical components are precision-manufactured and nickel-plated copper for superior longevity and conductivity.
The block offers a modular design, including an optional 4-port Through Terminal for flexible system integration.
To ensure a perfect start, the package includes necessary thermal paste, thermal pads, and putty.

This bespoke cooling solution underscores Thermal Grizzly’s commitment to blending high-end aesthetics with uncompromising thermal performance. Furthermore, the company already provides related hardware, including a GPU block for the Asus ROG RTX 5090 Astral, along with a comprehensive range of fittings and other liquid cooling accessories.

For the discerning enthusiast looking to elevate their RTX 5090 Suprim setup, the DeltaMate GPU Block Suprim is now available starting this month for €549.90. It’s time to stop merely managing heat and start mastering it.
