Thermal Grizzly Intel 1851 Mycro Pro RGB CPU Water Block

The Thermal Grizzly Intel 1851 Mycro Pro RGB is a high-performance CPU water block specifically optimised for Intel's LGA 1851 socket while remaining fully backward compatible with LGA 1700. This premium cooler features a nickel-plated copper cold plate with an ultra-high-performance structure of 70 microfins (each just 0.2mm wide) to provide a massive surface area for rapid heat dissipation. To ensure long-term reliability and consistent cooling, it incorporates a built-in fine-mesh filter at the inlet port to capture debris, alongside a flow-optimised jet plate and a tempered acrylic glass body for superior durability. Finished with an elegant anodised aluminium cover and integrated ARGB lighting that can be synchronised via a standard 3-pin motherboard header, this block offers a sophisticated aesthetic for any custom liquid-cooling loop. Whether you are pushing your system to its limits or seeking a silent, high-efficiency setup, the Intel 1851 Mycro Pro RGB provides a future-proof thermal solution with industry-standard G1/4in threads for seamless integration.

Intel 1851 Mycro Pro RGB

The Thermal Grizzly Intel 1851 Mycro Pro RGB is a CPU water block for Intel’s LGA1851 socket (backward compatible with LGA1700), featuring Ultra High Performance cold plates, a flow-optimised design, and an integrated filter.

Thermal Grizzly’s Intel 1851 Mycro Pro RGB is a CPU water block for Intel’s LGA1851 socket that is backward compatible with the LGA1700 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 Intel 1851 Mycro Pro RGB, both the slot and fin width on the nickel-plated copper cooling plate measure 0.2 mm. A total of 70 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.

• 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 Intel 1851 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 Intel 1851 Mycro Pro RGB is compatible with the Intel High Performance Heatspreader V1 (for the LGA1700 socket).
• The fluid inlet has been optimised for the LGA1851 (with stock heatspreader), but can also be used with LGA1700 socket CPUs.
• The G1/4-inch threads of the inlet and outlet ports are each 6 mm deep.
• The Intel 1851 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.
