What Thermal Grizzly does

Thermal Grizzly is a German PC thermal management specialist founded in 2013 by Roman Hartung (der8auer), headquartered in Hohen Neuendorf, Germany. The company designs, manufactures, and sells a comprehensive portfolio of thermal interface materials, custom liquid cooling components, GPU power monitoring devices, delidded CPUs, and installation tooling for PC enthusiasts, overclockers, and industrial customers. Core products include thermal pastes (Kryonaut, Kryonaut Extreme, Duronaut, Duronaut Pro, Hydronaut, Hydronaut Pro), liquid metals (Conductonaut, Conductonaut Extreme), thermal pads (Minus Pad series, KryoSheet graphene, PhaseSheet PTM), CPU/GPU water blocks (DeltaMate, Mycro Pro RGB lines with proprietary 0.2mm microfin coldplate technology), the patented WireView Pro II per-pin GPU power monitor (European Patent EP4250057), DeltaMate CNC-machined brass fittings, and delidded AMD/Intel processors backed by 24-month warranties. Manufacturing relies on precision CNC machining, proprietary graphene pad production processes, and validated thermal testing protocols.

The business operates a dual-channel GTM: direct-to-consumer e-commerce via thermal-grizzly.com (multilingual DE/EN/ES, EUR/USD) and a distribution network spanning 60+ countries across Europe, Africa, Asia, Australia/Oceania, North America, and South America, reaching DIY PC builders, gaming enthusiasts, custom water cooling builders, competitive overclockers, and industrial customers requiring non-silicone thermal solutions. Revenue is generated entirely through hardware sales at unit pricing ranging from €5.90 for accessories to €749 for delidded CPUs, with GPU water blocks commanding €399.90–€549.90 and premium CPU water blocks €139.90–€349.90. The company is privately held and founder-controlled, with no disclosed external funding, and is recognized through the EHA Awards 2026 for Best Thermal Interface Material (Duronaut) and Best Custom Cooling Brand, alongside the European Hardware Award and the first sponsorship of 3DMark's next flagship GPU benchmark.
