Are you planning to upgrade your PC's cooling system with a new custom block soon?
Thermal Grizzly has released the Mycro Pro Stainless Steel CPU water block series for global users. These blocks support a wide range of AMD and Intel sockets using an unplated copper cold plate design.
Why it matters
The unplated copper design is intended to facilitate direct heat transfer from the CPU heatspreader to the cooling system. By omitting nickel-plating, the company also reduces its overall manufacturing costs.
The AMD model contains 68 microfins while the Intel version features 70, with both utilizing 0.2mm slot and fin widths. The units are equipped with G1/4-inch ports and EPDM O-rings for standard compatibility.
The players
Thermal Grizzly
Thermal Grizzly is a German manufacturer specializing in high-performance cooling solutions and thermal interface materials for computer hardware.
The details
The Mycro Pro series utilizes stainless steel housing paired with an anodized aluminium mounting frame. These blocks are compatible with AMD AM4/AM5 sockets and Intel LGA1700/1851/1954 sockets, though they are not designed for direct-die cooling.
Timeline
The Mycro Pro series became available for purchase on September 23, 2026.
The Tech Race
This release reflects an industry pivot toward unplated copper designs that prioritize thermal efficiency over aesthetic or anti-corrosive plating. It positions Thermal Grizzly against established cooling manufacturers that continue to lean on traditional nickel-plated cold plates.
Users should note that the unplated copper cold plate will undergo natural discoloration over time due to oxidation. Owners must also ensure their system is compatible, as these units are strictly not intended for direct-die cooling setups.
The takeaway
When opting for unplated copper components, enthusiasts should be prepared for aesthetic changes resulting from oxidation. This hardware is a specialized tool for users looking to maximize heat transfer efficiency in their builds.
