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.
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.
**It should be noted that the temperature improvements achieved depend on several
factors. Besides the quality of the individual processors ("Silicon Lottery"), test results are
influenced by the room temperature and the cooling used, among other things. For an
AiO, for example, the cooling performance depends on factors like the pump speed as
well as the fans used. The values given are guidelines that can be higher or lower in
individual cases.

Short information
High Performance
AM5
Heatspreader
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.

Where it is worthwhile?
The AM5 High Performance Heatspreader is manufactured to the highest
quality standards at our production site in Germany. The entire production
chain is continuously monitored by our expertly trained personnel. Particu-
lar attention is paid to the diamond-milled precision surface, which is
specially protected from contamination during the production chain.
