Thermal Grizzly High Performance Heatspreader AM5

Thermal Grizzly introduces the AM5 High Performance Heatspreader, an upgrade heatspreader for AMD's Ryzen 7000 processors. The heatspreader's diamond-milled precision surface made of nickel-plated copper offers 240 percent more surface area compared to the original heatspreader. As a result, the AM5 High Performance Heatspreader enables maximum heat dissipation with air and water coolers.

Maximum heat dissipation due to increased surface area

The AM5 High Performance Heatspreader replaces the Socket Actuation Mechanism (SAM) of the motherboard and the heatspreader of the Ryzen 7000 processor. Thus, the processor has to be delidded. This enables an optimal contact pressure of the CPU into the socket and massively increases the surface of the copper heatspreader. The contact surface is diamond milled and offers extremely low surface roughness for best contact to the heatsink. The AM5 High Performance heatspreader offers 240 percent more surface area than the standard heatspreader! In practice, 10 °Celsius better temperatures can be achieved with the AM5 High Performance Heatspreader. In the test**, an AMD Ryzen 7900X (5.0 GHz, 1.3 vCore) is cooled with a 280 mm AiO. With the stock heatspreader, the maximum temperatures were about 90 °Celsius. With the AM5 High Performance heatspreader, the temperatures were below 80 °C. When the upgrade heatspreader was used in combination with the Thermal Grizzly AM5 Adapter & Offset Mounting Kit, the processor could be cooled down an additional 6 °C.

High compatibility in all areas

Another advantage of the AM5 High Performance heatspreader is its high compatibility. The upgrade heatspreader is compatible with popular AM5 mainboards and all air and water coolers. Compared to the AMD stock heatspreader, the overall height is 1.7 mm lower. This improves heat transfer and still allows mounting to almost all normal air and water coolers. For mono blocks, mounting height and heat transfer pads may need to be adjusted. If AIO or water coolers are limited in mounting height, we recommend the Thermal Grizzly AM5 Adapter & Offset Mounting Kit. The nickel-plated surface of the AM5 High Performance Heatspreader is also compatible with traditional thermal pastes and gallium-based liquid metals. The nickel forms a barrier layer between the liquid metal and the copper cooler, preventing liquid metal from diffusing into the copper and minimizing alloying. This usually eliminates the need for multiple applications of liquid metal. The AM5 High Performance Heatspreader is also compatible with Thermal Grizzly's AM5 backplates, which may be needed depending on the cooler. The Ryzen 7000 Delid-Die-Mate is recommended for delidding the processor. For the most maintenance-free system possible, a KryoSheet graphene thermal pad can be used as a thermal interface between the CPU and the AM5 High Performance Heatspreader. Since KryoSheet pads are electrically conductive, a cover is included to protect the electronic components on the CPU package.
