Product information "AM5 High Performance Heatspreader"

The AM5 High Performance Heatspreader is an upgrade heatspreader for AMD's Ryzen 7000 processors. The nickel-plated copper heatspreader features a 240 percent larger diamond-milled precision surface. This increased surface area over the original heatspreader allows for maximum heat dissipation with air and water coolers, while precision milling ensures extremely low surface roughness for best contact with the heat sink.

Optimized Heat Transfer and Reliable Protection

The nickel-plated surface of the AM5 High Performance Heatspreader is compatible with traditional thermal pastes and gallium-based liquid metals. The nickel forms a barrier layer between the liquid metal and the copper cooler, so liquid metal does not diffuse into the copper and alloying is minimized. As a result, multiple applications of liquid metal are generally not necessary.

For the best possible temperatures under load, we recommend using liquid metal as the TIM between the CPU and the High Performance Heatspreader.

2026 Update: Optimized Contact Surfaces and Expanded Compatibility

Starting with the 2026 production year, the AM5 High Performance Heatspreader is manufactured using a revised production process. This results in matte areas as well as optimized high-gloss contact surfaces. The polished high-gloss areas on the bottom surface indicate the relevant contact zones for applying liquid metal and improve heat transfer due to their optimized finish. This adjustment ensures compatibility with all AMD Ryzen 9000 processors. In addition, the version produced from 2026 onward is compatible with the AMD Ryzen 5 7400F.

Note on use with Kapton Insulation Sheets, Carbonaut, and KryoSheet

A thin layer of TG Shield should be used to insulate electronic components. The internal contour of the High Performance Heatspreader (HPHS) is optimized for the use of liquid metal, which can be applied in a very thin layer. The HPHS rests directly on the CPU package (PCB). When Kapton Insulation Sheets are used, there is a risk that the CPU die may not make contact with the HPHS if the HPHS rests on the Kapton Insulation Sheet and the resulting height difference between the CPU die and the HPHS becomes too large.

When thermal sheets such as Carbonaut and KryoSheet are used between the CPU die and the HPHS, the small height difference between the CPU die and the HPHS may result in excessive mounting pressure being applied to the CPU. This can cause operational issues, which may include incorrect memory detection or memory instability.

Note on Cooler Compatibility

The AM5 High Performance Heatspreader (HPHS) is thinner compared to the stock AMD heatspreader. This means that the surface of the HPHS is approximately 2 millimeters lower. Depending on the cooler's mounting kit, this might result in the CPU cooler not making contact with the surface of the AM5 High Performance Heatspreader.

Before retrofitting and powering on, we recommend verifying whether the CPU cooler can be mounted 2 mm lower in the Z-height from the motherboard. If the cooler’s mounting kit does not allow for a deeper installation, the AM5 Adapter & Offset Mounting Kit can provide a solution.

AM5 HP Heatspreader

Which cooler mounting hardware, backplate and additional frames do I need for AM5 High Performance Heatspreader?

Check the cooler’s achievable mounting height, intended stop and clearance. Do not force the installation by arbitrarily shortening screws or adding washers. The AM5 High Performance Heatspreader replaces the original AM5 heatspreader and the AMD SAM. It enables direct-die cooling with standard coolers such as AIOs or air coolers. In most cases, you can continue using the standard AM5 backplate. Whether a different backplate is needed depends on your cooler, and a replacement is generally unnecessary if the cooler is AM5-compatible. If you are unsure about a combination, send us the exact cooler and motherboard models along with photos of the mounting hardware. The AM5 High Performance Heatspreader sits approximately 2 mm lower than the original AMD heatspreader. The cooler must be able to reach this lower position. Depending on the cooler, the AM5 Adapter & Offset Mounting Kit may help. Make sure your cooler’s mounting height can be adjusted to allow it to sit 2 mm lower. An additional contact frame is not required because the HPHS replaces the CPU retention mechanism.

Which CPUs is AM5 High Performance Heatspreader designed for, and how does it replace the original heatspreader?

The AM5 High Performance Heatspreader is intended exclusively for compatible, delidded AM5 CPUs. The current version supports Ryzen 7000 and Ryzen 9000, including X3D and X3D2, as well as the Ryzen 5 7400F. Ryzen 8000G is excluded. For older versions, check the exact revision because the underside was modified in 2026. The AM5 High Performance Heatspreader replaces both the standard heatspreader and the AMD SAM.

How do I install AM5 High Performance Heatspreader, and what screw tightening sequence, mounting force or torque specification applies?

Install the AM5 High Performance Heatspreader with the system switched off and disconnected from power, following the instructions for the specific revision. Lay the motherboard flat and support any loose backplate. Use only the specified screws, start all screws loosely and tighten them evenly in the specified sequence. Tightening gradually in a cross pattern avoids excessive stress on the CPU dies.

Which thermal interface material is suitable for AM5 High Performance Heatspreader, and how is it applied?

We recommend a very thin, even layer of a suitable liquid metal, such as Conductonaut, between the exposed CPU dies and the AM5 High Performance Heatspreader. Protect the surrounding SMD components and prevent contact between the liquid metal and electrically conductive components such as SMDs under all circumstances. On the outer surface facing the cooler, you can use a thermal interface material suitable for both contact surfaces, such as KryoSheet or Duronaut Pro. Do not use additional sheets or insulating layers underneath the HPHS that alter the intended mounting height.

Is a new version or another model of AM5 High Performance Heatspreader planned?

The underside of the AM5 High Performance Heatspreader was revised in 2026. The current product page lists compatibility with Ryzen 9000, including X3D and X3D2, as well as the Ryzen 5 7400F. If you have an older HPHS, check its exact version before changing the CPU. We announce further models and release dates through our shop and official channels.

Why are temperatures with AM5 High Performance Heatspreader too high or higher than expected?

With the AM5 High Performance Heatspreader, first check the mounting height, correct screw set, even seating and the contact pattern of the thermal interface material. In most cases, excessive temperatures are caused by insufficient contact between the CPU and cooler. Bear in mind that the High Performance Heatspreader has a mounting height 2 mm lower than the original heatspreader of an AMD CPU. Then check the fans or pump, coolant flow and power draw. Compare temperatures under the same load and at the same room temperature. Due to CPU boost behaviour, better cooling may also result in higher performance. If die contact is incomplete, correct the mounting setup instead of simply tightening the screws further.

What are the dimensions, threads or connection spacings of AM5 High Performance Heatspreader?

The definitive dimensions, threads and mounting distances for the AM5 High Performance Heatspreader are provided in the technical drawing or instructions for the specific revision. If a required dimension is missing, send us the part number and identify the exact area of interference, if any. For cooler installation, it is particularly important to note that the contact surface sits approximately 2 mm lower than the original AM5 heatspreader.

What is included with AM5 High Performance Heatspreader, and how can I obtain missing or replacement parts?

The AM5 High Performance Heatspreader comes with an insulating sheet, four button-head screws, a 5/64-inch hex key and a Torx T20 key. The insulating sheet is only to be used when graphene pads are installed between the CPU dies and the heatspreader. If any parts are missing or you need replacements, send us the part number, proof of purchase and a photo of the accessories you received. We will check the availability of suitable replacement parts. Do not use unverified screws or spacers from other products.

Will AM5 High Performance Heatspreader fit my motherboard, and could it interfere with any components?

The AM5 High Performance Heatspreader is designed around AMD’s specified keep-out zone. However, some motherboards do not comply with it. When checking compatibility, consider not only the socket but also the exact motherboard revision, the components around the socket and the cooler mounting hardware. Particularly compact motherboards may have clearance conflicts even when the socket is compatible. If you are unsure, send us the full motherboard model and photos of the socket area from above and the rear of the motherboard.

Why does my PC fail to boot or detect the RAM after installing AM5 High Performance Heatspreader?

Switch off the system and disconnect it from power. After installing the AM5 High Performance Heatspreader, check that the CPU and heatspreader are seated correctly and that the screws have been tightened evenly according to the instructions. An incorrect mounting gap or uneven pressure from the CPU cooler can affect socket contact and RAM detection. Also check BIOS support and visible contamination. If in doubt, inspect the socket itself for bent pins. If the socket or die is damaged, do not run further tests. Instead, send us photos and the full system specifications.

How do I prevent damage or the CPU falling out when removing AM5 High Performance Heatspreader?

Lay the motherboard flat before loosening the AM5 High Performance Heatspreader. Remove the cooler, then loosen the High Performance Heatspreader screws gradually in a cross pattern. Lift it very slowly and vertically to check whether the CPU is still sticking to its underside. If it is, lift the heatspreader far enough to turn it over safely. Then remove the CPU from the heatspreader and clean it using a method suitable for the thermal interface material you used.

Where can I find the instructions, datasheet or technical drawing for AM5 High Performance Heatspreader?
