Thermal Grizzly has released the Mycro Pro stainless steel water block for CPUs, recommended for use as part of a custom liquid cooling system. The water block is available for AMD and Intel platforms. In addition to the current processor models LGA 1700 and LGA 1851, the Intel version also supports the LGA 1954 processor socket, which will be used by future Nova Lake-S series chips.

Intel models have input channels optimized for the LGA 1851 processor and a standard thermal cover. Thermal Grizzly also confirmed the compatibility of this version of the water block with Intel’s own LGA 1700 high-performance radiator V1 cap. The water block itself should be fitted with the processor’s heat sink cover – it is not suitable for direct die cooling of the die.
Despite the name “stainless steel,” the water block’s contact plate is made of copper without any coating. The water block body is made of stainless steel and the mounting frame is made of anodized aluminum. The Intel version comes with 70 microfins. The ribs themselves and the channels between them are both 0.2 mm wide.
Thermal Grizzly says eliminating nickel plating reduces manufacturing costs and may provide some advantages in heat transfer. But be aware that over time, bare copper surfaces may show signs of oxidation (discoloration). The water block is connected to the circuit of the customized liquid cooling system through two G1/4 connectors with a thread depth of 6 mm. EPDM O-rings are used to seal connections.
The waterblock version for AMD platforms supports AM4 and AM5 processor sockets and uses 68 microfins instead of 70. It’s compatible with the AM5’s custom Thermal Grizzly processor cover, and also mounts directly to the processor cover rather than the bare die.
Two versions of the Mycro Pro stainless steel head are now available. In the official Thermal Grizzly store, it sells for $116.88 (including VAT, but excluding shipping).
