Know before you buy
No, this product is specifically engineered for delidded AMD Ryzen 7000 series processors. It replaces the stock heatspreader and cannot be installed on a CPU that still has its original integrated heatspreader attached.
No, the Thermal Grizzly AM5 High Performance Heatspreader is not compatible with the Ryzen 8000G series. It is designed exclusively for the Ryzen 7000 series AM5 processors.
Yes, the nickel plating is specifically designed to minimize material diffusion, making it safe and effective to use with both traditional thermal pastes and gallium-based liquid metals.
This heatspreader is designed to be compatible with standard air and water cooling solutions. Because it replaces the stock hardware, ensure your cooler mounting mechanism can accommodate the specific dimensions of this unit.
The 240% larger surface area significantly improves heat dissipation efficiency. By providing more contact space for your cooler, it allows for better thermal transfer, which is critical for enthusiasts pushing their CPUs to higher clock speeds.
The kit includes the heatspreader and a cover for use with KryoSheet. Please note that you will need to provide your own thermal interface material and the necessary tools for the delidding process itself.
