Thermal Grizzly rolls out the DeltaMate GPU Block tailored for ASUS ROG Astral RTX 5080 cards, swapping the usual acrylic window for a Schott BOROFLOAT glass pane. The borosilicate material bends RGB light differently and resists alcohol‑based cleaners, giving the water block a distinct visual edge while simplifying maintenance.

Beyond the window, the block mirrors the DeltaMate family’s engineering: 0.2 mm microfins, full‑metal construction, and dual‑copper coldplates that target VRAM and VRM cooling. Users can choose a four‑port Through Terminal or a two‑port Direct Terminal, both brass‑finished, and receive thermal paste, pads, and putty out of the box.

Compatibility spans every ROG Astral RTX 5080 variant, from the standard 16 GB GDDR7 model to limited editions like WHITE and HATSUNE MIKU. By pairing precision‑blasted, nickel‑plated copper with a 13,440 mm² Core‑Coldplate surface, the design promises efficient heat extraction for the card’s high‑end silicon, delivering a ready‑to‑install solution for enthusiasts seeking both performance and showmanship.
