Arctic MX-7 vs Thermal Grizzly Conductonaut: Comparison
What is the difference between Arctic MX-7 and Thermal Grizzly Conductonaut?
The first real difference is electrical conductivity: Arctic MX-7 Insulating against Thermal Grizzly Conductonaut Conductive. Paste segment is not the same on both, Standard Paste on the Arctic MX-7 versus Liquid Metal on the Thermal Grizzly Conductonaut.
Arctic MX-7 vs Thermal Grizzly Conductonaut: which one fits your build
The Arctic MX-7 is the one to take 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 built 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. Take the Thermal Grizzly Conductonaut for experienced overclockers working with delidded CPUs or direct-die cooling. This is specifically the use case liquid metal is built for and where its conductivity advantage genuinely matters. It also earns its place with builders who fully understand and accept the electrical short-circuit and aluminum-corrosion risks. This product demands real technical confidence, not just a willingness to follow instructions once. Avoid it for GPU application under any circumstances. Every current guide is specific and unanimous on this point given how closely packed GPU components are. 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 (9/10): the benchmark liquid-metal compound for extreme cooling performance, but strictly for experienced builders comfortable with the short-circuit risk.
Frequently asked questions
Do the Arctic MX-7 and Thermal Grizzly Conductonaut differ on viscosity?
Yes. Viscosity reads 35000 Pa-s on the Arctic MX-7 versus 0.0021 Pa-s on the Thermal Grizzly Conductonaut.
Is the Min Operating Temperature the same on the Arctic MX-7 and Thermal Grizzly Conductonaut?
It is. Both are listed at -50 C, so it is not a reason to pick one over the other.
