This bundle includes the Thermal Grizzly AM5 Direct-Die CPU water block and Thermal Grizzly KryoSheet thermal pad. The AM5 Mycro Direct-Die is a water cooler for AMD's Ryzen 7000 processors that sits directly on the chiplets of a deliddeten (decapitated) CPU. Constructed from nickel-plated copper, the direct-die water cooler offers outstanding thermal conductivity. This is further increased by an optimized structure of the microfins on the top. In addition, direct-die cooling eliminates a layer of heat conducting agent and the CPU's heat spreader compared to normal water cooling. The AM5 Mycro Direct-Die 's nickel-plated finish is compatible with traditional thermal compounds and gallium-based liquid metals. A KryoSheet graphene thermal pad can be used as the thermal interface between the CPU and the AM5 Mycro Direct-Die for the most maintenance-free system possible. Since KryoSheet pads are electrically conductive, a cover is included to protect the electronic components on the CPU package. Thermal Grizzly KryoSheet series can be used as an excellent alternative for thermal compounds from the higher performance segment. Similar to the Carbonaut pads, they have an adaptable surface with very high thermal conductivity. Compared to Carbonaut pads, KryoSheet offers a significantly higher thermal conductivity as a high-end product. This increased thermal conductivity is based not only on the choice of material, but on the innovative manufacturing process. KryoSheet contains no liquid components and is therefore not subject to the usual aging that is the case with traditional thermal grease. Drying out is not possible. The KryoSheet Graphene Pads feature a Z-direction stacked molecular structure. This optimized structure enables excellent and constant thermal conductivity.
