Thermal Grizzly - KryoSheet (24x12x0,2mm) - Graphene Thermal Pads - Highest Thermal Conductivity - Alternative to High Performance Thermal Paste CPU/GPU/PS4/PS5/Xbox

Product Information

This increased thermal conductivity is not only due to the choice of material, but also to the innovative manufacturing process. KryoSheet does not contain any liquid components and is therefore not subject to normal ageing as is the case with traditional thermal paste. Drying out is not possible. COOLER: XPG Levante 240 mm (Thank you, XPG!), Thermal Grizzly Carbonaut, IC Graphite, GD900-1, Deepcool Z3, Cooler Master Mastergel Maker, Thermal Grizzly Kryonaut, Thermal Grizzly Kryonaut Extreme. Compared to Carbonaut pads, KryoSheet, as a high-end product, offers significantly higher thermal conductivity. This increased thermal conductivity is not only due to the choice of materials, but also to the innovative manufacturing process. KryoSheet contains no liquid components and is therefore not subject to normal aging, as is the case with traditional thermal paste. Drying out is not possible. The plan moving forward is to continue benchmarking this system monthly or bi-monthly to assess whether the performance remains consistent. Another test will be conducted on a different build featuring a custom loop cooling system with a 3080 GPU and a 5900x CPU in a Lian Li q58 case with a 360mm radiator. This will provide further insights into the applicability of KryoSheet.

The goal of these tests is to determine whether the Thermal Grizzly Kryonaut and Kryonaut Extreme thermal pastes can deliver good performance, and how they compare to other thermal interface alternatives that have been previously tested. The following texts contain more details about the methodology and how the tests were conducted. Testing results: The easy application and longevity of the KryoSheet pads are plus points here. The long durability of the pads means that they are maintenance-free. In addition to applications in industry, for example in the construction of servers, this is also an advantage in domestic PC construction or in the OEM sector. Because the pads do not have to be replaced at regular intervals like thermal paste, there is no need for extensive maintenance. The graphs below shows the delta T (ΔT), which is the difference between the CPU temperature (in this case) and the ambient temperature, thereby eliminating the ambient temperature from the equation. Both versions of the Thermal Grizzly Kryonaut performed very well when tested right after application, with the Kryonaut slightly outperforming its “extreme” counterpart and surpassing the Cooler Master Mastergel Maker by almost 2 K in this scenario. However, after some thermal cycles, also known as “curing time”, both versions of Kryonaut showed a decrease in performance, with an increase of about 2 K in delta temperature. This might not be very promising for long-term use in regular situations.Thermal Grizzly is introducing a new product called KryoSheet , which is one of the company's advertised "High Performance Cooling Solutions". The graphene thermal pads of the Thermal Grizzly KryoSheet series can be used excellently as an alternative to thermal pastes from the higher performance segment. Similar to the Carbonaut pads, they have an adaptable surface with very high thermal conductivity. There is limited data available on long term performance due to how new KryoSheet is. Additionally, different CPUs may exhibit varying results. While KryoSheet worked well with the 5800x3D, it may not perform as effectively with denser CPUs like the 5900x or 5950. It's also essential to consider how GPUs perform and whether there's a difference between water-cooled and air-cooled builds.

We tested the thermal paste immediately after application/cooling assembly and again in the next day, after a few “heat-cool” cycles, alternating between 40 minutes of idle and 40 minutes of stress in AIDA. The idea is to verify whether the thermal paste has any curing time, i.e., whether there is a difference in performance between the freshly applied product and the one that has undergone some thermal cycles. The graphene thermal pads of the Thermal Grizzly KryoSheet series can be used as an excellent alternative for thermal compounds from the higher performance segment. Similar to Carbonaut pads, they have a conformable surface with very high thermal conductivity. Compared to Carbonaut pads, KryoSheet as a high-end product offers significantly higher thermal conductivity. Due to the optimized thermal conductivity of KryoSheet compared to Carbonaut, the focus of the graphene pads is on enthusiast products in the end customer segment as well as on industrial applications. Examples of the use of KryoSheet include refurbishing used graphics cards and notebooks/laptops. In the above table, the max temps are lower, however that is just one data point in time. The average temperatures over a 10-20 minute idle period are a lot lower with the KryoSheet than they are with the thermal paste by approximately 3 degrees Celsius. A cover made of anodized aluminum is magnetically attached to this. 13 RGB LEDs integrated into the cover illuminate the side acrylic glass and the G1/4-inch threads. The cover can be mounted so that the RGB connection cable can be routed up or down. The RGB lighting is connected via a 3-pin ARGB header (+5V/DATA/GND).In the end, both Kryonaut models performed the best right after application, with Kryonaut slightly outperforming its Extreme counterpart. However, after the “curing” process, both thermal pastes lost some performance, showing a difference of about 2 K compared to the initial test. Die Graphen-Wärmeleitpads der Thermal Grizzly KryoSheet-Serie können hervorragend als Alternative für Wärmeleitpasten aus dem gehobenen Leistungssegment genutzt werden. Ähnlich wie die Carbonaut-Pads besitzen sie eine anpassungsfähige Oberfläche bei sehr hoher Wärmeleitfähigkeit. Im Vergleich zu Carbonaut-Pads bietet KryoSheet als High-End-Produkt eine deutlich höhere Wärmeleitfähigkeit. This is not an ideal result, as it raises questions about whether the performance loss will continue to increase over time. Some reports online suggest that this could indeed happen. Conclusion:

In these tests, was used the Ryzen 7 2700X @ 4.1GHz 1.3375V LLC 3 and VDDSOC 1.025V, with memory set at 3200MHz XMP. We used Blender to render the “Classroom” demo for 30 minutes to obtain the results.The objective of this was to evaluate the effectiveness of Thermal Grizzly Kryosheet in comparison to conventional thermal paste. Kryosheet offers the advantage of prolonged longevity without the risk of drying out, reducing the maintenance burden, especially when used in conjunction with hard-line water tubing systems where disassembly can be cumbersome. In contrast, traditional thermal paste typically requires reapplication every 6 to 24 months, depending on the specific type used and the conditions used in. For this experiment, rather than applying fresh thermal paste to a system assembled six months ago, I opted to run the system with its existing thermal paste and compare it to the performance of Kryosheet. This approach aims to underscore the longevity benefit of Kryosheet. Additionally, this study draws inspiration from a recent video by Jayz2Cents that also compared fresh thermal paste with Kryosheet.
