Thermal Grizzly has added AMD’s Ryzen 7 9850X3D to its lineup of delidded CPUs, catering to overclockers and liquid-metal cooling enthusiasts. The move follows the earlier release of delidded versions of the Ryzen 7 9800X3D and Ryzen 9 9950X3D, positioning the company as a key supplier for high-performance, direct-die cooling solutions.
The delidded Ryzen 7 9850X3D is priced at $876.33—significantly higher than the $500 MSRP for the stock model—but comes with a two-year warranty covering manufacturing defects and overclocking within manufacturer specifications, provided adequate cooling is maintained. The warranty explicitly excludes physical damage to the silicon, SMD components, or the PCB.
Thermal Grizzly’s CEO, Roman Hartung—better known as Der8auer—has documented the performance and thermal benefits of delidding in a YouTube video. Testing the Ryzen 7 9850X3D in Cinebench R23, Hartung observed peak temperatures of 90.2°C on one CCD and an average die temperature of 88.1°C during a 10-minute benchmark run, with power draw peaking at 182.35W. After applying liquid metal and direct-die cooling, temperatures dropped to a range of 66.1–75.3°C, representing a roughly 15°C reduction across the board while maintaining a slightly lower peak power draw of 178.09W.
The delidded variant also demonstrated improved overclocking potential, as highlighted in Hartung’s video. This aligns with the growing trend among enthusiasts to push hardware beyond standard limits, particularly for 24/7 workloads like rendering or gaming servers.

For users considering extreme cooling setups—such as phase-change systems or actively chilled loops—the delidded Ryzen 7 9850X3D represents a compelling option, particularly for high-end workstations or 24/7 operation. However, the premium pricing reflects both the specialized nature of the product and the risks associated with delidding, including potential voiding of standard manufacturer warranties.
Thermal Grizzly’s expansion into the Ryzen 9000X3D series underscores the demand for custom cooling solutions among power users, especially as AMD continues to refine its 3D V-Cache architecture for performance gains. The company’s warranty policy suggests confidence in the delidding process but also acknowledges the inherent risks of direct-die modification.
