Overview
The Thermal Grizzly Mycro Pro Stainless Steel is an enthusiast-grade custom liquid-cooling CPU water block engineered for high heat-flux dissipation across modern socket architectures. Its fluid dynamics foundation relies on an ultra-fine microchannel array featuring 0.2 mm microfins and 0.2 mm slot widths, deploying 70 microfins on Intel variants and 68 on AMD platforms. By utilizing a bare, unplated copper cold plate, the block intentionally foregoes the standard nickel-electroplated barrier to minimize thermal interface resistance directly against integrated heat spreaders. Liquid distribution is routed through standardized G1/4-inch threaded inlet and outlet ports, enabling seamless integration into established custom loop infrastructures.
Constructed for structural durability, the housing is machined from heavy S304 stainless steel, supported by an anodized aluminum mounting bracket and industrial-grade EPDM (ethylene propylene diene monomer) O-ring seals. This choice of resilient elastomer delivers superior resistance to ozone cracking, UV degradation, and thermal cycling compared to traditional nitrile gaskets, while eliminating the cracking risks inherent to acrylic water blocks. Although the block operates purely passively with no moving mechanical components, onboard electronics, or firmware overhead, builders must account for natural cosmetic surface oxidation on the raw copper plate over extended service intervals. Cross-platform versatility is secured through comprehensive socket coverage, including native forward-looking compatibility spanning Intel LGA 1700, LGA 1851, and LGA 1954, alongside AMD AM4 and AM5.
