The Thermal Grizzly Mycro Direct-Die CPU Water Cooler RGB for Socket AM5

The AM5 Mycro Direct-Die RGB is a water cooler for AMD's Ryzen 7000 processors that sits directly on the chiplets of a delidded CPU. Made of 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, compared to normal water cooling, direct-die cooling eliminates the need for a layer of thermal conductive material as well as the CPU's heatspreader. This significantly improves the heat transfer from the CPU to the water cooling circuit.

Visually, the AM5 Mycro Direct-Die RGB offers a stylish appearance. On the nickel-plated base plate is a block of acrylic glass, which is subjected to a annealing process after milling. The annealing process removes internal surface stresses from the acrylic. This ensures that no stress cracks form in the acrylic glass even after a long period of use.

Powerful CPU water block with RGB lighting

A cover made of anodized aluminum is magnetically attached to this. 13 RGB LEDs integrated into the cover illuminate the side acrylic glass and the G1/4-inch threads. The cover can be mounted so that the RGB connection cable can be routed up or down. The RGB lighting is connected via a 3-pin ARGB header (+5V/DATA/GND).

The AM5 Mycro Direct-Die RGB's nickel-plated finish is compatible with traditional thermal pastes and gallium-based liquid metals. The nickel forms a barrier layer between the liquid metal and the copper cooler, preventing liquid metal from diffusing into the copper and minimizing alloying. As a result, multiple applications of liquid metal are generally not necessary.

For the most maintenance-free system possible, a KryoSheet graphene thermal pad can be used as the thermal interface between the CPU and the AM5 Mycro Direct-Die RGB. Since KryoSheet pads are electrically conductive, a cover is included to protect the electronic components on the CPU package.
