Precision engineered waterblocks from Thermal Grizzly are designed to extract maximum thermal performance from both CPUs and GPUs. At their core is advanced microfin cold plate technology, which dramatically increases surface area to accelerate heat transfer directly at the die. Paired with optimised flow channels, this ensures efficient coolant distribution across hotspots, delivering consistently low temperatures even under sustained high loads.
Each waterblock features CNC machined housings crafted to tight tolerances, resulting in exceptional build quality, durability, and a flawless seal within custom loops. With model-specific fitment, these blocks are engineered for perfect contact and compatibility with individual CPU sockets and GPU PCBs.
The Mycro Pro is Thermal Grizzly’s flagship CPU water block, built around an ultra-high-performance nickel-plated copper cold plate with microfin architecture. A fine-mesh filter at the inlet guards against debris, and the integrated RGB lighting makes it a visual centrepiece as well as a performance one.
The DeltaMate range covers full-coverage GPU water blocks for high-end graphics cards, including model-specific versions for the ASUS ROG Astral RTX 5080 and 5090. Built with a Schott BOROFLOAT borosilicate glass viewing window – more durable than acrylic and with a distinctive light refraction through the integrated RGB.
The DeltaMate fittings family is purpose built to perfectly complement the high performance waterblocks from Thermal Grizzly, delivering both seamless integration and uncompromising reliability in any custom loop.
Designed with versatility in mind, the range includes rotary fittings for flexible routing, extenders for precise spacing, pass-through fittings for clean case integration, and plugs for secure sealing. Each component is precision-machined to exacting tolerances, ensuring a leak-free fit and consistent performance under demanding conditions.

Thermal Grizzly’s ecosystem extends well beyond thermal paste and pads, with a growing lineup of intelligent accessories designed to enhance both performance and safety. The WireView Pro II stands out as a patented GPU power connector monitor, purpose built for modern high power graphics cards and demanding system configurations.
Designed specifically for 12V-2×6 connectors, the WireView Pro II provides real-time monitoring of per pin current, giving users unprecedented visibility into power delivery at the connector level. This proactive approach helps detect uneven load distribution and potential failure points addressing the well documented connector issues that have affected high end GPUs in the RTX 40 and 50 generation, and offering an extra layer of protection for critical hardware.
The WireView Pro II monitors every individual pin of your GPU’s 12V-2×6 connector, not just total current. A built-in TFT-IPS display shows live per-pin current, voltage, temperature and power consumption. If any pin exceeds safe thresholds, an audible and visual alarm triggers – and the system can be configured to shut down automatically. An extended 2-year warranty covers your GPU connector should damage occur despite the device being in use.

Thermal Grizzly’s thermal compounds are trusted by overclockers, reviewers, and system builders who demand consistent, measurable results across a wide range of workloads. Known for their reliable application properties and proven thermal performance, these pastes are engineered to deliver efficient heat transfer whether in everyday systems or highly tuned enthusiast builds.
The lineup spans three core formulations, covering everything from cost effective solutions for budget builds to high performance compounds for advanced cooling setups and extreme overclocking scenarios. Each variant is optimised for its specific use case, balancing thermal conductivity, ease of application, and long-term stability to ensure dependable performance under both standard and demanding conditions.
The enthusiast standard
The most widely used Thermal Grizzly paste. High thermal conductivity, smooth application, and reliable performance across a wide range of cooler types. The go-to choice for air and AIO coolers.
Built to last
Engineered for exceptional long-term stability using aluminium microparticles and zinc oxide nanoparticles. Minimises the pump-out effect and maintains performance over years of thermal cycling. Includes the TG Spatula Pro for thin-layer application.
Great value, great performance
A lower-viscosity paste ideal for larger contact surfaces and beginners. Easy to spread evenly, with solid thermal performance for standard builds and gaming PCs.
Not all surfaces are suited to traditional thermal paste components like VRAM chips, VRMs, and areas with uneven height or spacing require materials that can properly bridge gaps and maintain consistent contact. Thermal Grizzly addresses this with a focused range of specialist solutions designed for these more demanding scenarios.
From high performance thermal pads for clean, repeatable installation, to flexible compounds that adapt to surface variation, and advanced gap fillers for complex layouts, each option is engineered for a specific application. This ensures optimal heat transfer, reliable mounting pressure distribution, and long term stability across components where standard paste simply isn’t enough.
Graphene. No paste needed.
A graphene thermal pad with higher conductivity than any traditional paste in this class. Solid at room temperature, virtually no pump-out effect, and extremely long-lasting. Ideal as a paste replacement on CPUs and GPUs.
Electrically conductive – follow application instructions carefully.
Phase-change performance
Solid at room temperature, liquefies above 45 degrees C to fill micro-gaps between surfaces. Minimises pump-out through its phase-change cycle. More durable than traditional paste, great for CPUs with high contact pressure coolers.
The gap filler for GPU mods
A flexible, mouldable thermal putty designed for GPU conversions and custom cooler installs where standard pads do not fit. Fills 0.2-3.0mm gaps and can be shaped by hand or spatula to fit VRAM, VRM, and backplate surfaces. Available in Basic, Advance, and Pro conductivity tiers.
For builders chasing the absolute lowest CPU temperatures, liquid metal represents the final frontier in thermal performance. Thermal Grizzly’s Conductonaut range pushes far beyond the limits of conventional thermal paste, using a gallium based formulation with exceptionally high thermal conductivity to maximise heat transfer directly from the die to the cooler.
Favoured by competitive overclockers and direct die enthusiasts worldwide, Conductonaut is designed for scenarios where every degree counts. Its ability to dramatically reduce thermal resistance makes it ideal for extreme tuning and delidded CPUs, though it demands careful application and compatible materials, rewarding experienced users with unmatched cooling performance.
Conductonaut is a gallium-based liquid metal compound with exceptional thermal conductivity. Applied directly between the CPU die and cooler base (or between IHS and die after delidding), it eliminates the performance ceiling of conventional pastes. The trade-off is a more involved application process and material compatibility requirements.
Liquid metal is electrically conductive and will corrode aluminium surfaces. It should only be used with copper or nickel-plated cooler bases. Not suitable for use on GPU dies or surfaces where containment cannot be guaranteed. Ideal for experienced builders who understand the application process.
