Thermal Grizzly Unveils High-End Diamond-Plated Water Block for Delidded CPUs

• June 5, 2026

At Computex 2026, Thermal Grizzly revealed an experimental water block designed specifically for delidded processors, integrating diamond plates for enhanced thermal conductivity. This new cooling solution targets enthusiasts and professionals seeking to push CPU performance through improved temperature management.

Innovation in Liquid Cooling for Delidded CPUs

The showcased water block employs direct contact cooling that leverages diamond material to boost heat transfer away from the CPU. Diamond is known for its exceptional thermal conductivity, which makes it a promising choice for high-performance cooling systems. By incorporating diamond plates, Thermal Grizzly aims to significantly reduce thermal resistance between the processor and the cooling medium.

This water block is intended for CPUs that have undergone delidding, a process where the integrated heat spreader (IHS) is removed to allow for improved thermal interface material application and better cooling efficiency. Using diamond plates in tandem with liquid cooling enhances those benefits further, potentially enabling higher overclocking headroom and lower operating temperatures.

With an estimated cost starting at around €1500, the Thermal Grizzly water block positions itself as a premium solution targeting the niche market of advanced PC builders and hardware enthusiasts. Although pricing details remain preliminary, the high cost reflects the use of specialized materials and the complex manufacturing process.

This announcement underscores ongoing innovation in PC cooling technologies, especially as users and manufacturers continuously seek ways to improve the performance and longevity of high-end CPUs. While the product remains experimental, Thermal Grizzly’s approach could influence future cooling hardware designs that prioritize extreme efficiency and quality.

Further details about availability and specific performance metrics have not been disclosed. However, this development highlights the increasing role of exotic materials like diamond in overcoming thermal challenges in modern computer hardware.
