New: Software and First Firmware Update for WireView Pro II
The official launch of the first public software suite for the GPU power monitoring tool WireView Pro II, along with the first official firmware update, has arrived. Both the software and the firmware update are optional. However, when used together, they enable full functionality of the WireView Pro II, including data logging and device configuration via PC.
Important:
WThe WireView Pro II is available for pre-order in the Thermal Grizzly Shop.
Shipping of the second batch of the WireView Pro II started in January 2026,
further deliveries will follow in mid-March.
The WireView Pro II has been specifically developed for the demanding use of modern high-end graphics cards with the 12V-2x6 connector and represents the most advanced iteration of the WireView Pro. As a patented development by Thermal Grizzly, it is protected by European patent EP4250057. Current is not only measured as a total value, but also per each individual pin and wire of the 12V-2x6 connector. This enables immediate identification of potential contact issues between the cable and graphics card. The WireView Pro II has been purpose-built to enable precise monitoring of the 12V-2x6 connector, allowing early detection of load distribution problems and helping to prevent possible damage to the graphics card and the 12V-2x6 connector.
Monitoring
All safety-relevant parameters such as currents (A), voltages (V), temperatures (°C), and power consumption (W) are continuously measured. Thermal Grizzly has defined threshold values which should not be exceeded during regular operation, since doing so would increase the risk of thermal damage to the connector. When a threshold is exceeded, a visual warning appears on the display and an audible alarm is triggered. Optionally, automatic system shutdown can be initiated via the included splitter cable. The preset threshold values can be adjusted through the configuration menu.
Cooling
Due to unavoidable contact resistances at plug connections which result in power loss, additional heat is generated during the operation of high-performance GPUs. To ensure controlled heat dissipation, a semi-passive fan has been integrated, which operates silently at idle and activates automatically with increasing power draw and temperature. The CNC-machined aluminum housing features ventilation openings and serves as an active heatsink. Optimized openings in the rear PCB guide airflow around all heat-relevant components including the graphics card power connector.
User-Friendliness
The WireView Pro II is available with two connector orientations and can therefore be used with nearly any graphics card that has a 12V-2x6 connection. The downward-facing input connector orientation allows clean cable routing, since the device functions as a 90-degree adapter at the same time. The integrated TFT-IPS display provides multiple layouts that can be configured directly on the device. The device functions as a standalone hardware solution and can be used and configured without a software connection. Additional customisation and system reporting will be expanded in the future with software support. A corresponding update is planned for mid-December.
Automatic Data Logging
An integrated memory logs relevant operating data at regular intervals to enable traceability of potential error events. Logged values include per pin current measurements, total power consumption and the PCB temperature near the 12V-2x6 output connector (T-Out). A data record is stored every 60 seconds. The memory supports approximately 340 days of continuous usage or around 3-4 years of typical operation before the older entries are automatically overwritten. The collected data supports both failure analysis and the continued development of safer plug connections within the community.
Extended Warranty and Clarity for the End User
To ensure a high level of operational safety, the WireView Pro II includes an extended warranty that goes beyond statutory warranty and the standard manufacturer guarantee. Should damage occur to the 12VHPWR or 12V-2x6 connector of the graphics card despite the integrated protective mechanisms, repairs will be performed by Thermal Grizzly or an equivalent replacement will be provided if a repair is not possible. This protection also applies after the original graphics card warranty has expired. It is required for any warranty claim that the device is used properly, in accordance with the user manual and within the operating parameters defined by the GPU manufacturer. The extended warranty period is 2 years from the date of purchase.
This guaranteed protection package provides maximum transparency and safety. The customer invests in state-of-the-art monitoring technology and can rely on Thermal Grizzly to offer fast and straightforward support in case of damage, ensuring maximum performance without unnecessary risk.

Duronaut is a high-end thermal paste designed with a focus on outstanding thermal conductivity and exceptional long-term stability. The name "Duronaut" derives from the English word "durability," emphasizing its extraordinary longevity. This stability is achieved through a specially engineered silicone oil combined with aluminum microparticles and zinc oxide nanoparticles of various shapes. These optimized particle shapes and sizes minimize the "pump-out effect," ensuring excellent adhesion to surfaces and resulting in extremely low thermal transfer resistance.
Extreme long-term stability
Outstanding thermal conductivity
Electrically non-conductive
No hardening over time
The optimized particle shapes and sizes enable Duronaut to be applied in very thin layers, enhancing adhesion and minimizing thermal resistance. This thin application layer, coupled with the high conductivity of the aluminum micro and zinc oxide nanoparticle mix, ensures efficient heat transfer between the heat source (e.g., a CPU) and the cooler.
For optimal application, the TG Spatula Pro is included with Duronaut. The spatula's revised design allows for increased pressure during application, ensuring efficient spreading and a thinner layer of thermal paste.
Scope of Delivery
1x Duronaut
1x Applicator
1x TG Spatula
1x TG Spatula Pro
TG Putty is an electrically non-conductive alternative to conventional thermal pads. As an easy-to-apply and flexible gap filler, it compensates for height differences, making it ideal as a replacement for thermal pads on GPUs. Graphics cards typically feature several types of thermal pads of varying thicknesses from the factory, requiring different pads during replacement or when converting the cooler to a GPU water cooler.
TG Putty can be applied using the included spatulas or by hand (gloves recommended). The spatula allows for broad application, while by hand, it can be shaped into small pellets tailored to the surface size (e.g., VRAM, SMD). TG Putty can fill height differences ranging from 0.2 to 3.0 mm.
TG Putty is available in three variants, primarily differing in their thermal conductivity:
TG Putty Basic: Medium thermal conductivity
TG Putty Advance: Good thermal conductivity
TG Putty Pro: Excellent thermal conductivity
For modifying a single, smaller graphics card without an active backplate (e.g., GeForce GTX 1060), approximately one 30-gram container of TG Putty is required. For larger graphics cards, such as a GeForce RTX 4090, one 30-gram container is generally sufficient for the memory (VRAM) and voltage regulators (VRM) on the front side. On the backside, there is often a uniform, larger gap between the PCB and the backplate on larger graphics cards. In this case, approximately two 30-gram containers are needed to completely fill this gap.
Notes:
TG Putty is not suitable for use on processors (IHS or Direct Die) or directly on the GPU die!
Before application, the target surface should be thoroughly cleaned and degreased, for example, using TG Cleaning Wipes or conventional isopropanol.
Scope of Delivery

The phase-change material on which the PhaseSheet PTM is based is solid at room temperature. The material only begins to liquefy at temperatures above 45 degrees Celsius. A high contact pressure of around 300-400N is required for optimum distribution of the liquid PhaseSheet PTM and thus the lowest possible layer thickness. PhaseSheet PTM has a very low viscosity in its liquid state and contracts again when it changes to a solid material, thus minimizing the pump-out effect.
The pump-out effect is particularly pronounced when combining a copper cooler on a graphics chip because silicon and copper have different linear expansion when heated. The temperatures under load cause the heatspreader and the base plate to deform (concave or convex) and return to their original shape (straight) when they cool down. As a result, the thermal paste is slowly pressed out between the heatspreader and the base plate of the CPU cooler, for example.
Outstanding thermal conductivity
Consistently high performance
Very long service life
Versatile in application
Not electrically conductive
Easy to use
PhaseSheet PTM is more durable than traditional thermal pastes, but not as durable as KryoSheet, for example, which is virtually maintenance-free. PhaseSheet PTM develops and stabilizes its maximum thermal conductivity after around ten thermal cycles above 60 degrees Celsius.
Scope of Delivery
1x PhaseSheet PTM
The graphene thermal pads 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 pads, they have an adaptable surface with very high thermal conductivity. Compared to Carbonaut pads, 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.
Outstanding thermal conductivity
Easy to use
Consistently high performance
Extreme durability
Attention: Electrically conductive! Follow the instructions!
The KryoSheet graphene pads have a molecular structure stacked in the Z-direction. This optimized structure allows for outstanding and consistent thermal conductivity. This is due to a specially developed manufacturing process in which the hexagonal crystal structure of the graphite is broken up along the basal plane in order to be able to exploit the anisotropy of the thermal conductivity of the graphite. As a side effect of this complex manufacturing process, however, the electrical conductivity is also increased and the stability of the KryoSheet pads is influenced, so that the pads can only be used according to instructions!
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 is available in multiple sizes – matched to different CPU and GPU models.
