Thermal Grizzly AMD AM5 Mycro Pro RGB CPU Water Block

The Thermal Grizzly AMD AM5 Mycro Pro RGB is a high-performance CPU water block meticulously engineered for the AM5 platform, while offering full backward compatibility for AM4 sockets. This premium cooler features an ultra-high-performance nickel plated copper cold plate equipped with 68 microfins (each just 0.2mm wide) to provide an expansive surface area for rapid heat dissipation from your processor. A standout innovation is the integrated fine-mesh filter at the inlet port, which captures particles from the cooling loop to prevent clogging and ensure consistent thermal efficiency over time. Constructed from high-quality materials including tempered acrylic glass and a sleek anodised aluminium cover, the Mycro Pro RGB offers a sophisticated aesthetic enhanced by customisable ARGB lighting. With industry-standard G1/4in threads and a flow-optimised jet plate, this water block is an expertly refined choice for enthusiasts looking to maintain peak performance and system longevity in a custom liquid-cooling setup.

AMD AM5 Mycro Pro RGB

The Thermal Grizzly AM5 Mycro Pro RGB is a CPU water block for AMD’s AM5 socket (backward compatible with AM4), featuring Ultra High Performance cold plates, a flow-optimised design, and an integrated filter.

Thermal Grizzly’s AM5 Mycro Pro RGB is a CPU water block for AMD’s AM5 socket that is backward compatible with the AM4 socket. The cooler consists of a nickel-plated copper cold plate, a cooler plate made of tempered acrylic glass, a jet plate for flow optimisation, and a cover made of anodised aluminium. The G1/4" threads ensure compatibility with a wide range of water-cooling products, such as the Thermal Grizzly DeltaMate fittings.

Ultra High Performance Cold Plate

Thermal Grizzly’s Ultra High Performance cold plates for CPU and GPU coolers are milled with minimal and highly optimised slot and fin widths. In the case of the AM5 Mycro Pro RGB, both the slot and fin width on the nickel-plated copper cooling plate measure 0.2 mm. A total of 68 microfins are located on the cold plate of the CPU water block. This high number of thin fins provides a very large surface area, allowing the coolant to dissipate heat quickly and efficiently. The cooler design milled into the acrylic glass, including a jet plate, is optimised for flow and delivers outstanding cooling performance in combination with the highly optimised cooling fins.

• Inlet and outlet ports with standard G1/4" threads
• Compatibility list available online

Integrated Filter for Consistently High Cooling Performance

The integrated filter captures particles present in the water-cooling loop. These may include production residues, for example from radiators. To prevent the microfins in the copper cooler from becoming clogged, these particles are filtered out directly at the inlet port. Contamination of the microfins can impair the flow of the coolant and thereby reduce cooling performance. This may result in higher CPU temperatures. The filter helps delay this effect and can be cleaned if necessary.

Ports and RGB Lighting

The AM5 Mycro Pro RGB is integrated into a custom water-cooling loop via one inlet and one outlet, each featuring G1/4-inch threads in the acrylic glass. A fine-mesh filter in the form of a sieve is located at the inlet port. After milling, the acrylic glass undergoes an annealing process that relieves internal stresses, reducing the risk of stress cracks over long periods of use. Beneath the cover is RGB LED lighting that accentuates the clean design when illumination is desired. The RGB LEDs can be controlled via a 3-pin ARGB header (+5V/DATA/GND) through the motherboard. The sealing rings used (O-rings) are made of highly elastic EPDM (ethylene propylene diene rubber), which is resistant to ozone and UV radiation.

Product-Specific Notes

• The AM5 Mycro Pro RGB is not compatible with the AM5 High Performance Heatspreader. To use both products together, the AM5 Adaptor & Offset Mounting Kit is required.
• The G1/4-inch threads of the inlet and outlet ports are each 6 mm deep.
• The AM5 Mycro Pro RGB is not compatible with Direct-Die.

General Notes on Water-Cooling Products

• Do NOT use in combination with water-cooling components made of aluminium where the coolant comes into contact with aluminium, such as radiators with aluminium tubing.
• We recommend suitable coolants that contain biocides and corrosion inhibitors and are free of particles that could restrict water flow or clog the loop.
• The custom water-cooling system should be tested for leaks with an air pressure tester for at least 1 hour before filling.
• After filling, the system should be regularly inspected during the first 24 hours for any potential coolant leaks.
