Thermaltake TG-30 4g Thermal Compound

Thermaltake TG-30 is a grey thermal paste supplied in a 4.0g syringe with a honeycomb stencil and scraper. Its diamond-powder formula achieves 4.5 W/mK conductivity and remains stable across a long-term operating range of -50 to 200 C. The non-electrically conductive grease resists drying and cracking over a 24-month shelf life.

Builders seeking easy application

This kit suits DIY builders who want a syringe, stencil and scraper for a thin, even layer without soiling fingers. It fits CPUs and GPUs in new builds or older systems needing fresh paste. Buyers needing larger volumes for multiple installations or higher conductivity ratings should look elsewhere.

4.5 W/mK thermal conductivity rating

The 4.5 W/mK figure determines heat-transfer capability between the processor IHS and cooler base. Viscosity is rated at 76 Pa-s for controlled spreading. If your cooling solution demands a different conductivity value, this compound will not match that requirement.

Questions about this item

Will the 4.0 g syringe with its 7.05" x 3.5" x .59" packaging fit inside a cramped mini-ITX case during the build?

The paste itself is only 4.0 g of compound; the 7.05" x 3.5" x .59" box is external packaging you discard, so the syringe takes negligible space inside any case.

The kit includes a honeycomb stencil and scraper — what is the step people most often skip when using them?

Many users forget to place the stencil flat on the IHS before spreading the 76 Pa-s grease with the scraper, leading to uneven coverage and air pockets.

With a 24-month shelf life, how do I keep the remaining TG-30 usable for a future CPU swap?

Recap the syringe tightly and store it upright at room temperature; the non-drying formula stays viable for the full 24 months when sealed properly.
