Arctic MX-7 vs Thermal Grizzly Conductonaut Extreme: Comparison
Arctic MX-7 vs Thermal Grizzly Conductonaut Extreme: the electrical conductivity difference
The first real difference is electrical conductivity: Arctic MX-7 Insulating against Thermal Grizzly Conductonaut Extreme Conductive. They differ on recommended use too, Mainstream CPU/GPU, High-end CPU/GPU on the Arctic MX-7 versus Delidded-Direct-Die on the Thermal Grizzly Conductonaut Extreme. Paste segment is not the same on both, Standard Paste on the Arctic MX-7 versus Liquid Metal on the Thermal Grizzly Conductonaut Extreme.
Who each one is for
Buy the Arctic MX-7 for MX-4 and MX-6 users wanting Arctic's newest formula and builds with exposed SMD components near the die, though it is not the pick for buyers who want a published W/mK figure to compare and anyone who prefers spreading paste with a spatula. It is equally the pick for GPU, console and laptop repastes where pump-out is the main concern. The Thermal Grizzly Conductonaut Extreme suits GPU dies and vertical mounting setups and builders who've had migration issues with standard Conductonaut. It is not the one for first-time liquid metal users, standard Conductonaut with careful application is still the more common starting point. Our rating of the Arctic MX-7 (8.7/10): Arctic's newest flagship compound, positioned as a genuine step up over MX-6 for enthusiasts chasing the last few degrees. Our rating of the Thermal Grizzly Conductonaut Extreme (8.7/10): A version of Conductonaut tuned for larger dies, offering top-tier performance with the same liquid-metal handling risks.
