The premium cooling solution promises advanced features and innovative design choices tailored for custom liquid cooling builds.
Key Takeaways
- Designed for AMD AM5/AM4 and Intel LGA1851/LGA1700 sockets
- Uses nickel-plated copper and brass construction with borosilicate glass window
- Hybrid microfin layouts for optimal thermal performance
- ARGB lighting for visual customization
- AM5 model available now, priced at approximately $409
Premium Cooling Design for Enthusiasts
Thermal Grizzly’s DeltaMate MPII series offers robust construction, catering to high-end PC builders. Both AMD and Intel models utilize nickel-plated copper cold plates and nickel-plated brass housings. A distinctive feature is the borosilicate glass viewing window, allowing users to monitor coolant flow directly. The anodized aluminum outer cover not only adds durability but also provides an option to conceal mounting screws for a sleek aesthetic.

Advanced Microfin Architecture
The performance-driven approach of the DeltaMate MPII lies in its cold plate engineering:
- AM5 Version:
- Features a hybrid layout with 25 microfins (0.2mm spacing) over CPU core areas (CCDs)
- 29 wider fins (0.4mm spacing) above the I/O die to distribute coolant efficiently
- Intel Version:
- Harnesses 40 microfins (0.2mm spacing) over the CPU tile
- Additional 30 fins (0.3mm spacing) above and below this section further optimize coolant path
This ensures precise thermal management for both current and previous generation processors, as the blocks are backward compatible with AM4 and LGA1700 sockets.

Integrated ARGB Lighting and Versatile Mounting
Both models include vivid ARGB lighting, controllable through a standard 3-pin 5V motherboard header, letting users sync cooling visuals with the rest of their build. The standard G1/4-inch ports allow compatibility with most custom loop hardware.
For easier installation and refined appearance, the DeltaMate MPII includes a detachable cover that hides mounting screws and hardware, enhancing the overall system presentation.
Availability and Pricing
The AM5-compatible DeltaMate MPII model is immediately available, with an official price point of just over $400, including VAT in some markets. The Intel LGA1851 variant will arrive shortly after. Both models underline Thermal Grizzly’s focus on pairing performance with modern design, targeting enthusiasts building the most advanced desktops in 2024.
