Thermal Grizzly Conductonaut Liquid Metal Thermal Paste - High

In this review the Thermal Grizzly Conductonaut Liquid Metal paste is assessed for users who demand the lowest possible CPU and GPU temperatures. The bottom line: this is a specialist product for experienced builders who want extremely high thermal conductivity and measurable temperature reductions. It is presented as a 5 g combo with extra applicators and is best used where copper or nickel-plated heat spreaders and cold plates are present; it delivers clear cooling gains but requires care during application.

Key Features

• Extremely high conductivity: The liquid metal formula provides much higher heat transfer than typical silicone-based greases, helping cores reach lower steady-state temperatures.
• Long action stability: The compound remains stable over extended use so benefits persist after initial installation when applied correctly.
• Immediate temperature drop: Users report instant reductions in CPU and GPU temperatures, which can lower fan noise and improve comfort.
• Cost effective per dose: The 5 g combo and extra applicators can cover many DIY applications, offering strong value for experienced technicians.
• Not for aluminum: The formulation must not be used on aluminum components due to corrosion risk, so compatibility checks are essential.

Who It's For

The Conductonaut liquid metal paste is aimed at experienced PC builders, overclockers, and technicians who are comfortable disassembling coolers and handling conductive products. If you want to squeeze maximum thermal performance from a CPU or GPU and can avoid aluminum contact, this paste delivers significant gains.

It is not recommended for users who prefer an easy drop-in upgrade without risk or those working with aluminum heatsinks. If you need a nonconductive, beginner-friendly compound, a silicone-based thermal grease is a safer choice.

Pros & Cons

Pros

• Very high thermal conductivity that reduces operating temperatures and fan noise.
• Stable performance over extended use so benefits remain long term.
• Good value for experienced users since the 5 g can service multiple builds with the extra applicators.

Cons

• Conductive and corrosive to aluminum, so it is unsafe for aluminum contact and requires careful application.
• Some users find it tricky to spread compared with paste-style compounds, so handling skill is required.

Frequently Asked Questions

Can I use this on all heatsinks?
Do not use Conductonaut on aluminum parts; it is safe on copper and nickel-plated surfaces only.

How much does 5 g cover?
The 5 g combo with extra applicators can cover many builds and is reported usable for up to 30 CPUs depending on how much is applied.

Is it beginner friendly?
Not particularly; the liquid metal is conductive and can be harder to spread, so it suits experienced DIYers comfortable with careful application.
