Thermal Grizzly AMD Mycro Direct-Die Pro CPU Water Block

The AMD Mycro Direct-Die Pro RGB V1 is a water cooler optimized for the AMD AM5 platform, featuring a nickel-plated copper baseplate and RGB lighting. Compared to the standard version, the Pro version offers a hybrid structure of microfins and reduced flow resistance. The direct-die cooler is placed directly on the silicon of the delidded AMD CPU.

The AMD Mycro Direct-Die Pro RGB V1 features a hybrid structure with two different sizes of microfins and a jet plate for optimized flow. The cooler's cold plate is made of nickel-plated copper and is mounted directly on the CPU chip. For this, the Socket Actuation Mechanism (SAM) of the motherboard is removed, and the processor must be delidded. The nickel plating of the cooler plate creates a barrier layer, preventing gallium-based liquid metal from diffusing into the copper, making multiple applications of liquid metal usually unnecessary.

• Water cooler for direct-die mounting
• Microfin cooler made of nickel-plated copper
• Replaces SAM and heatspreader
• Acrylic and aluminum cover
•  G1/4-inch connections
• CPU compatibility list available online
• For delidded CPUs only! Caution: voids warranty!

Between the cold plate and the anodized aluminum cover, there is acrylic glass, which undergoes an annealing process after milling to relieve internal stress. This ensures that no stress cracks form in the acrylic glass over time, unlike hardened acrylic glass. RGB LEDs are located under the aluminum cover and are controlled via a 3-pin ARGB header (+5V/DATA/GND) through the motherboard. The LEDs illuminate the acrylic glass under the cover and the G1/4-inch connectors on the cover.

Attention: Removing the heatspreader (“delidding”) of a processor is at your own risk! The manufacturer's warranty expires when the CPU is delidded! Damage caused by delidding the CPU is not covered by the manufacturer's warranty!

Removing the Socket Actuation Mechanism (SAM) of the mainboard may invalidate the manufacturer's warranty of the mainboard manufacturer!
