Corsair TM30 Review

TM30 was Corsair's first thermal paste release, built as an accessible entry point alongside its cooler and case lineup rather than a flagship performance play. It ships with an applicator for consistent dosing, a detail aimed squarely at builders who don't already have an application routine.

Thermal Performance and Conductivity

Corsair doesn't publish a consistent thermal conductivity figure for TM30 across its own materials, so this number needs manufacturer confirmation before it appears in filters or comparisons. Independent reviews generally place it in the mainstream performance bracket rather than the high-conductivity tier occupied by Kryonaut or TFX.

Compound Type and Composition

TM30 is a zinc oxide based compound, per Corsair, marketed around low thermal impedance rather than a headline W/mK figure.

Application and Consistency

The included applicator is the main differentiator here, designed to help builders new to thermal paste apply a consistent, even amount without guesswork.

Electrical Safety

Non-conductive. TM30 is non-conductive, so it carries no short-circuit risk if it spreads past the heat spreader.

Longevity and Pump-Out Resistance

Manufacturer-rated interval isn't consistently published. Confirm against current Corsair documentation before publishing a specific timeframe.

Comparison to Alternatives

Against Corsair's own XTM50, covered elsewhere on this site, XTM50 targets a higher performance bracket for a higher price, making TM30 the more budget-conscious choice within Corsair's own lineup. Against Arctic MX-4, TM30 competes on being an easier first-time application experience thanks to the included applicator.

Who This Paste Is Actually For

First-time builders who want a straightforward, applicator-guided application.

Corsair-ecosystem builds pairing with Corsair coolers or cases.

Not for: Builders chasing the highest published conductivity numbers, where Corsair doesn't compete on paper against TFX or Kryonaut.

Not for: High-end overclocking builds better served by XTM50 or a liquid metal compound.

Pending Verification

Compound Type: Metal oxide (zinc oxide based, per Corsair).

Thermal Conductivity: Not consistently published by Corsair.

Reapplication Interval: Manufacturer-rated interval not consistently published.
