About the DeltaMate GPU Watercooler ROG Astral RTX 5090
Our much-anticipated DeltaMate GPU Water Block for the ROG Astral RTX 5090 will be the first GPU Block produced in Germany by Thermal Grizzly. It features exemplary surface finish and attention to detail with a dual finish machined copper coldplate that is glass blasted and re-machined prior to nickel plating. Underpinned by the same 0.20mm micro-fins as our Mycro CPU Water Blocks and supplied with Thermal Grizzly Duronaut, Minus Pad Advance and Putty Advance this is built to perform.
There have been some delays that make our initial schedule of availability during July 2025 unlikely. To avoid any further disappointment, we will not be announcing a specific launch date or enabling pre-orders for this product. Instead, you can check this news article for regular and transparent updates on the status and tasks that remain ahead of us.
