Carbon-Based Thermal Paste

Lirealar TF8 is a carbon-based thermal compound rated at 13.8 W/mK for desktop and laptop CPU, GPU and LED coolers. The 5.8 g syringe targets builders who want a non-electrically-conductive paste that remains stable across extreme temperatures. It is not suited for users who need a larger volume for multiple system builds or industrial-scale applications.

Wide Operating Range

The compound operates from -220 °C to 380 °C with thermal resistance below 0.01 °C·cm²/W and density of 2.9 g/cm³ at 25 °C. Being non-curing and non-corrosive, it maintains consistent thermal transfer without hardening or degrading, keeping cooler noise and power draw unaffected over time.

Spreader Tool Included

A spreader tool ships with the syringe to help achieve an even layer and minimise air gaps during application. The paste is non-toxic and designed to last at least six years without re-application, reducing maintenance effort for the installed hardware.

Questions about this item

How do I apply the TF8 paste with the included tool and what step do beginners often miss?

Spread a thin, even layer using the supplied applicator; the step many skip is cleaning both CPU and cooler surfaces completely before application.

Will the 5.8 g syringe need replacing and after how long?

The compound is rated to last at least six years without curing or degrading, so replacement is not expected within that period.

At what temperature does the paste hit its operating limit during heavy loads?

The long-term operating range tops out at 380 °C, which is the first thermal boundary reached under sustained use.
