Thermal Grizzly Aeronaut (Metal-Oxide/Silicone Based/Non-Conductive/8.5 W/mK/Entry-Level Pick) Review
Aeronaut is Thermal Grizzly's entry point into its own lineup, explicitly marketed by the brand as an ideal entry-level thermal paste. At 8.5 W/mK, it matches Arctic MX-4 and MX-6 on conductivity while carrying Thermal Grizzly's name, giving budget-conscious builders a lower-cost option from a premium brand.
Aeronaut is Thermal Grizzly's entry point into its own lineup, explicitly marketed by the brand as an ideal entry-level thermal paste. At 8.5 W/mK, it matches Arctic MX-4 and MX-6 on conductivity while carrying Thermal Grizzly's name, giving budget-conscious builders a lower-cost option from a premium brand.
Thermal Performance and Conductivity
Rated at 8.5 W/mK, Aeronaut matches Arctic MX-4 and MX-6 directly, sitting well below Thermal Grizzly's own Kryonaut at 12.5 W/mK.
Compound Type and Composition
A metal-oxide and silicone based compound, positioned as Thermal Grizzly's accessible tier below Kryonaut, without liquid metal's conductivity ceiling or safety trade-offs.
Application and Consistency
Thermal Grizzly markets Aeronaut as compatible with most cooling solutions, including console hardware like PS4, PS5, and Xbox, spreading evenly across both small desktop dies and larger surfaces.
Electrical Safety
Fully non-conductive, with no short-circuit risk from generous or imperfect application.
Longevity and Pump-Out Resistance
Thermal Grizzly markets Aeronaut as wear-resistant and rated across a wide temperature range (-150°C to +200°C per brand materials), though a specific reapplication interval should be confirmed against current documentation.
Comparison to Sibling Products
Against Thermal Grizzly's own Kryonaut, covered elsewhere on this site, Kryonaut rates meaningfully higher on conductivity for a higher price, making Aeronaut the entry point and Kryonaut the upgrade within the same brand. Against Arctic MX-4, Aeronaut matches conductivity closely, with the choice coming down to brand preference and package size options.
Who This Paste Is Actually For
Entry-level builds and first-time thermal paste buyers wanting a recognized brand at a lower price point.
Console repasting (PS4, PS5, Xbox) and general-purpose CPU/GPU application.
Not for: High-end or overclocked builds better served by Kryonaut within the same brand.
Not for: Builders specifically chasing the highest conductivity number in this category.
Pending Verification
Reapplication Interval: Brand materials claim wear resistance but no rated interval.
