Thermal Grizzly, which previously sold delidded Ryzen 7 9800X3D processors, has added the Ryzen 7 9850X3D to its lineup. These CPUs are functionally identical to AMD’s stock parts—originally sold with an Integrated Heatspreader (IHS)—but the IHS has been removed, allowing direct‑die cooling solutions.
Available Models and Pricing
Thermal Grizzly now offers four delidded CPU models:
| Model | Link | US Price* |
|---|---|---|
| AMD Ryzen 7 9800X3D | Tom’s Hardware | $794.43 |
| AMD Ryzen 7 9850X3D | Tom’s Hardware | $876.33 |
| AMD Ryzen 9 9950X3D | Tom’s Hardware | $1,168.83 |
| Intel Core Ultra 9 285K | Tom’s Hardware | $934.83 |

Warranty
Because AMD and Intel do not warranty modified CPUs, Thermal Grizzly provides its own warranty:
- 24‑month warranty from the date of purchase.
- For the first year, the company covers “nearly any chip failure” that isn’t caused by obvious user damage.
- The warranty excludes damage from overclocking beyond the manufacturer’s specified values and any use of the original heatspreader.
Compatibility and Usage Notes
- The chips are marketed as “optimal for TG Direct‑Die cooling solutions.”
- The Ryzen 9 9950X3D is not compatible with Thermal Grizzly’s Direct‑Die frames.
- The stock heatspreader must never be used; doing so voids the warranty.
- Although the original heatspreader is included, it is intended only for storage or repurposing (e.g., as a keychain).

Considerations for Direct‑Die Cooling
- Delidded CPUs eliminate the air gap created by stock heatspreaders, improving thermal transfer but increasing the risk of die damage during heatsink installation.
- Proper spacing of the cooling solution is essential; both AMD and Intel stock heatspreaders are relatively thick, so a direct‑die cooler must be designed for a lid‑less chip.
- Users should be comfortable handling bare dies and understand the mechanical risks involved.
