Thermal Grizzly Luxurious Water Block for RTX 5090 Launched at $585
One of Thermal Grizzly's latest releases is the DeltaMate GPU Block Astral-a complete liquid cooling solution for the ASUS ROG Astral RTX 5090 graphics card. The cost for this premium product is nothing short of exorbitant if one considers the efficiency with which the product intends to take away heat from a flagship GPU.
Designed for Maximum Cooling Performance
Several of the design features highlighted by the manufacturer pertain to performance. The water block is said to be made fully from metal and therefore able to cool all major components of the graphics card, from the VRAM to the VRM.
- The back side of the water block uses Thermal Grizzly Minus Pad Advance thermal pads and Duronaut thermal paste.
- Cooling plates feature micro-ribs, as thin as 0.2 mm, to maximize heat-transfer surface area.
Assembly and Components Included
There is a fair amount of configurability for custom loop builders with the DeltaMate GPU Block Astral, as it can be configured with either direct (2-port) or optional through-hole (4-port) brass fittings.
Please note that the given price is only for the water block itself; further auxiliary pieces for the custom liquid cooling loop (tubing, radiator, pump, etc.) are not covered.
Pricing and Market Context
The Thermal Grizzly DeltaMate GPU Block Astral retails for $585 in the US. For price context, the manufacturer claims that an equivalent amount could easily get a "factory overclocked" GeForce RTX 5070 graphics card.
