Thermal Grizzly DeltaMate Premium CPU Block - MPII INTEL 1851 - Black / Glass

The Thermal Grizzly DeltaMate CPU Block – MPII Intel 1851 is engineered for enthusiasts looking to maximise cooling performance from Intel’s latest high-performance processors. Optimised for socket LGA1851 and backwards compatible with LGA1700, the DeltaMate combines an Ultra-High-Performance nickel-plated copper coldplate with a substantial nickel-plated brass housing, Schott BOROFLOAT® glass viewing window and integrated ARGB lighting.

Its hybrid microfin coldplate is specifically designed around the CPU tile layout, using ultra-fine 0.2 mm structures across the primary heat-producing area alongside larger 0.3 mm fins for optimised coolant distribution. A machined aluminium backplate, magnetic aluminium cover and robust G1/4-inch connections complete a CPU water block designed for premium custom cooling systems.

Ultra-High-Performance hybrid coldplate

At the heart of the DeltaMate CPU Block – MPII Intel 1851 is Thermal Grizzly’s Ultra-High-Performance coldplate, precision-machined from copper before being nickel-plated for a durable, premium finish.

The coldplate uses a hybrid microfin structure developed specifically around the layout of compatible Intel processors. Across the CPU tile area are 40 extremely fine cooling fins, each featuring a 0.2 mm fin width and 0.2 mm slot width.

This dense microfin structure creates a substantial surface area through which heat can be transferred rapidly from the processor into the coolant.

Above and below the CPU tile area, the coldplate incorporates a further 30 fins with a width of 0.3 mm. These larger structures are designed to optimise coolant distribution across the coldplate, balancing high heat transfer capability with effective flow through the block.

Solid brass construction

The DeltaMate is built around a substantial solid brass housing which is nickel-plated for durability and corrosion resistance. Combined with the nickel-plated copper coldplate, this gives the water block an exceptionally robust full-metal construction.

Its inlet and outlet use standard G1/4-inch threads and are offset towards the upper-right side of the housing. This positioning provides durable connection points for your fittings while leaving the internal coldplate structure clearly visible through the glass window.

Each G1/4-inch thread has a depth of 6 mm.

Schott BOROFLOAT® glass and ARGB lighting

A premium Schott BOROFLOAT® borosilicate glass viewing window provides a clear view of the DeltaMate’s internal cooling structure, while integrated addressable RGB lighting highlights the block from within.

The lighting connects to a compatible motherboard or RGB controller through a standard 3-pin 5V ARGB connection (+5V / Data / GND), allowing the water block to be synchronised with the rest of your system lighting.

Borosilicate glass refracts the integrated RGB illumination differently from conventional acrylic, producing a distinctive appearance around the viewing window. Following waterjet cutting, the edges of the Schott BOROFLOAT® glass are finished by hand to further enhance the effect.

Beyond appearance, borosilicate glass also offers excellent UV resistance, high scratch resistance and improved resistance to alcohol-based cleaning products compared with acrylic.

Two visual configurations

The DeltaMate CPU Block includes a black anodised aluminium cover which attaches magnetically to the water block.

This allows the block to be installed in two different visual configurations. Fit the cover for a cleaner appearance that conceals the mounting hardware and screws, or remove it to expose more of the DeltaMate’s mechanical full-metal construction.

Machined aluminium backplate

Included with the Intel version of the DeltaMate is a dedicated LGA1851 backplate manufactured from milled aluminium and finished with black anodising.

The backplate forms part of the mounting system and complements the premium construction of the water block while providing a secure installation platform for compatible Intel processors.

LGA1851 and LGA1700 compatibility

The DeltaMate CPU Block – MPII Intel 1851 is optimised for Intel’s LGA1851 socket while retaining backwards compatibility with LGA1700, making it suitable for both current and previous-generation Intel platforms.

It is also compatible with the Thermal Grizzly Intel High Performance Heatspreader V1 when used with socket LGA1700.

Ready for installation

Thermal Grizzly includes TG Duronaut thermal paste, the dedicated LGA1851 backplate, required mounting hardware and installation tools with the block.

Each DeltaMate CPU Block is also supplied with a pressure test certificate for 1 bar. When installed in a custom water-cooling loop, Thermal Grizzly specifies a maximum operating pressure of 0.6 bar.
