Are you planning to upgrade your PC's cooling system with a new custom block soon?
Thermal Grizzly has launched the Mycro Pro series of CPU water blocks for AMD and Intel sockets. The hardware, which is available now, utilizes an unplated copper cold plate to improve heat transfer performance.
Why it matters
By eliminating nickel plating, these blocks focus on direct heat transfer from the processor heatspreader to the coolant. The series aims to provide a high-performance cooling alternative for enthusiasts using current desktop socket architectures.
The AMD model features 68 microfins while the Intel version contains 70, with both utilizing a 0.2mm slot and fin width design. These blocks support AM4/AM5, LGA1700, LGA1851, and LGA1954 sockets using standard G1/4-inch ports.
The players
Thermal Grizzly
A developer of high-performance thermal interface materials, cooling solutions, and hardware accessories for PC overclockers.
The details
The design replaces conventional nickel-plated surfaces with an unplated copper cold plate to facilitate direct thermal contact. The structure is reinforced by a stainless steel housing and an anodized aluminium mounting frame, connected via EPDM (ethylene propylene diene monomer) O-rings. The system is engineered for standard heatspreader use rather than direct-die cooling applications.
Timeline
September 23, 2026: The Mycro Pro series became available for purchase.
The Tech Race
The Mycro Pro series represents the latest refinement in the competitive aftermarket CPU cooling market. It marks a shift toward specialized material choices to squeeze additional performance from high-TDP processor architectures.
The Mycro Pro series is available now for €99.90, though users should anticipate natural oxidation and discoloration of the copper plate over time. These units are designed for standard CPU cooling and are not compatible with direct-die thermal management.
The takeaway
The move toward unplated copper highlights the industry-wide push to minimize thermal resistance in liquid cooling loops. Enthusiasts should monitor long-term performance reviews to see if the natural oxidation of the copper plate affects sustained cooling efficiency.
