Thermal Grizzly KryoSheet Thermal Pads

Product information "KryoSheet"

The graphene thermal sheets of the Thermal Grizzly KryoSheet series can be used excellently as an alternative to thermal pastes from the upper performance segment. Similar to the Carbonaut sheets, they have an adaptable surface with very high thermal conductivity. Compared to Carbonaut sheets, KryoSheet offers significantly higher thermal conductivity as a high-end product. This increased thermal conductivity is not only due to the choice of material, but also due to the innovative manufacturing process. KryoSheet does not contain any liquid components and is therefore not subject to ordinary aging as is the case with traditional thermal paste. Drying out is not possible.

Note on use with High Performance Heatspreaders and Direct-Die coolers

When thermal sheets such as Carbonaut and KryoSheet are used between the CPU die and the HPHS, insufficient mounting pressure may result in reduced heat dissipation. For Direct-Die coolers and the HPHS, the use of liquid metal between the CPU die and the cooler or HPHS is explicitly recommended.

KryoSheet is available in multiple sizes

The KryoSheet 24×12 mm is compatible with:

CPUs:

Intel Mobile CPUs

AMD GPUs:

RX 6400
RX 6500 XT

Note

Multiple use of KryoSheet is not recommended!

When disassembling the cooler and handling the KryoSheet after use, micro-cracks may occur in the structure of the graphene pads, which can affect performance.

KryoSheet

What size of KryoSheet do I need, and how do I cut it to fit?

Choose the size of KryoSheet according to the actual CPU or GPU contact area. You can find a size guide in the KryoSheet downloads section. It lists the most common CPUs and GPUs. KryoSheet should be slightly larger than the area to be covered. Avoid contact with electrically sensitive elements such as SMD components or exposed contacts. If necessary, cover them with TG Shield or TG Kapton Insulation Sheet, for example.

Which version of KryoSheet suits my application, and what thermal conductivity and cooling performance does it offer?

KryoSheet is a dry alternative to thermal paste for low-maintenance, long-term use. KryoSheet and Carbonaut are electrically conductive. KryoSheet offers higher thermal conductivity, while Carbonaut provides a particularly flexible contact surface. PhaseSheet PTM, by contrast, is an electrically non-conductive phase-change material. Choose based on the contact area, mounting pressure and installation requirements. The temperature you can achieve depends on power consumption, the cooler, the contact surfaces and installation. A fixed temperature advantage over other thermal interface materials therefore cannot be specified for every system. Thermal Grizzly has not published general W/(m·K) ratings since the end of 2020. A single thermal conductivity value does not allow a reliable comparison of cooling performance, as the test method, temperature, mounting pressure and contact surfaces all affect the result.

Is KryoSheet electrically conductive, and how do I prevent short circuits?

KryoSheet is electrically conductive. The sheet must not touch exposed contacts or adjacent components that are electrically sensitive. If necessary, use suitable insulation outside the thermal contact area. Remove all loose offcuts. If necessary, cover them with TG Shield or TG Kapton Insulation Sheet, for example.

How do I prevent KryoSheet from slipping during installation?

Work on a level surface and place KryoSheet on the side that will not move during installation. For example, place it on the CPU installed in the motherboard, so that only the cooler moves during installation. KryoSheet also includes an application oil. This can be applied to the CPU or GPU before installing KryoSheet and prevents the pad from slipping during installation.

Is KryoSheet suitable for direct-die cooling or a delidded CPU?

KryoSheet is very well suited to exposed GPU dies and delivers very high performance. In direct-die CPU applications, the power density may be too high, resulting in moderate performance. For these applications, Thermal Grizzly recommends liquid metals such as Conductonaut or Conductonaut Extreme.

Can I continue using KryoSheet after disassembly or if it has visible damage?

We advise against reusing KryoSheet. Removal and repositioning can create invisible microcracks that impair cooling performance. Use a new sheet when changing the cooler. Visible tears, holes or sharp creases are also reasons to replace it. Remove all loose conductive particles. If the sheet arrived damaged, document its condition before installation and contact your local retailer or Thermal Grizzly.

Is KryoSheet suitable for laptop CPUs and GPUs?

KryoSheet may be suitable for CPU or GPU contact surfaces in a laptop, provided the cooler sits flat and the available mounting pressure is sufficient. Remember that it is electrically conductive and keep the sheet away from adjacent components. Larger gaps, such as those around VRAM or VRMs, must be filled with thermal pads or putty.

Can I combine KryoSheet with thermal paste, liquid metal or other thermal interface materials?

Use KryoSheet as the sole thermal interface material between the two contact surfaces. Internal tests did not demonstrate any improvement from additionally using liquid metal or paste between KryoSheet and the surface. Application oil explicitly supplied for installation is a separate matter and must only be used according to the instructions.

What is included with KryoSheet, and how can I obtain missing parts?

The package contains KryoSheet in the selected size. The exact quantity and any installation aids are listed under the corresponding item number. If you think an accessory is missing, always compare the contents with this specific list. Products packaged from 2026 onward include application oil and TG Kapton Insulation Sheet for insulation. An authentication card is not automatically included with every sheet product. Report any listed parts that are missing, and include proof of purchase and a photo of the package.

Why are temperatures with KryoSheet too high or higher than expected?

Check the size and position of KryoSheet, ensure the contact surfaces are clean, and verify the cooler's seating and mounting pressure. KryoSheet requires moderate to high mounting force to work well. Also check the fans or pump (for liquid cooling), and compare temperatures at the same room temperature and power consumption. The sheet must not have slipped or become creased. Unsuitable insulation must not create a gap between the contact surfaces. Follow the cooler manufacturer's specified mounting forces. Tightening further does not compensate for an incorrect setup.

How long does KryoSheet last in use, and when should I replace it?

KryoSheet does not dry out like conventional thermal paste and can remain in the system long term if correctly installed and left undisturbed. Routine replacement after a fixed number of years is not intended. When disassembling, mechanical damage and contamination must be taken into account.

What mounting pressure does KryoSheet require, and is it suitable for uneven contact surfaces?

KryoSheet requires flat contact surfaces and even mounting pressure within the cooler's specifications. It cannot compensate for a larger mechanical gap or an incorrect mounting height. Tighten the screws only as specified by the cooler manufacturer. The required mounting pressure depends on the contact area and mounting bracket. A mounting pressure above 0.2 N/mm² achieves very good results.

Can I use KryoSheet in a games console?

The suitability of KryoSheet depends on the console model, contact area and mounting pressure. Not every sheet is suitable as a replacement for thermal paste at a contact area designed for it. A factory-installed liquid metal setup should not be modified without checking it first either. Pay particular attention to electrical conductivity and clearance from surrounding components. For a specific recommendation, tell us the console model and the contact area concerned.

How do I remove KryoSheet or clean the contact surfaces?

Carefully lift KryoSheet off the contact surface and avoid pulling on the edges. Then clean the CPU or GPU and the cooler with a material-compatible cleaner and a lint-free cloth, for example TG Cleaning Wipes. Do not wash or soak the sheet itself in an attempt to restore it. Remove all loose conductive particles.

How can I check whether my KryoSheet is genuine, and what should I do if the verification code is invalid?

If you have doubts about authenticity, please contact our support team with proof of purchase and photos.

What temperature range and extreme conditions is KryoSheet suitable for?

KryoSheet was developed for temperatures from −250 to +150 °C. This range alone does not establish suitability for every mechanical installation or special application. Also observe the temperature limits of the CPU, GPU, cooler and all adjacent materials.
