Thermal Grizzly Expands Delidded AMD Ryzen 9000 CPU Lineup for Enthusiasts

Thermal Grizzly has broadened its range of delidded AMD Ryzen 9000 series CPUs, catering to PC enthusiasts seeking optimal thermal performance through direct-die cooling solutions. The initiative began with the AMD Ryzen 7 9800X3D and later included the Ryzen 9 9950X3D. The latest addition is the AMD Ryzen 7 9850X3D, now available for purchase directly from Thermal Grizzly.

Delidded Ryzen 7 9850X3D: Pricing and Warranty Details

The delidded AMD Ryzen 7 9850X3D is listed at $876.33 on the Thermal Grizzly store, a significant premium over the standard $500 MSRP. This price reflects the specialized delidding process and the inclusion of a comprehensive two-year warranty. The warranty covers manufacturer defects and issues that may occur during the delidding process, as well as overclocking within AMD’s official specifications, provided that adequate cooling is used. However, it does not extend to physical or liquid damage affecting the silicon, SMDs, or PCB.

Performance and Thermal Improvements with Direct-Die Cooling

Roman Hartung, also known as Der8auer—a renowned overclocker and CEO of Thermal Grizzly—recently showcased the delidding process and its benefits in a detailed YouTube demonstration. Using Cinebench R23, Hartung tested the Ryzen 7 9850X3D before and after delidding. Initially, the CPU reached a peak temperature of 90.2°C on one CCD, with an average die temperature of 88.1°C and a peak power draw of 182.35 W during a 10-minute benchmark run. Individual core temperatures ranged from 78°C to 88.2°C.

After applying liquid metal and installing a direct-die cooling solution, the CPU’s peak core temperatures dropped to between 66.1°C and 75.3°C, with the average CPU temperature peaking at 75.3°C. This represents a reduction of approximately 15°C across all cores. The peak package power draw also decreased slightly to 178.09 W, with BIOS settings kept consistent throughout the tests.

Overclocking Potential Enhanced by Delidding

Hartung further explored the overclocking capabilities of the delidded Ryzen 7 9850X3D using the direct-die cooling setup. The improved thermal headroom allows for more aggressive tuning while maintaining safe operating temperatures, making these delidded CPUs an attractive option for enthusiasts aiming to push their systems to the limit.
