Maxtor CTG8D 12.8W/mK 4.0g thermal paste

Maxtor Thermal CTG8D is a 4.0g syringe of thermal compound rated at 12.8W/mK. It is formulated to transfer heat between a CPU or GPU and its cooler. The non-conductive paste eliminates short-circuit risk during application. It operates reliably from -50 to 250 C.

Suited for overclockers and high-TDP builds.

This paste targets enthusiasts running high-TDP processors or graphics cards who need above-average thermal conductivity. The 2025 ITSMA report notes proper grease use can extend device lifespan by 20 to 40 percent. Builders with standard 6 to 9W/mK requirements or those seeking a lower-cost option for basic cooling should look elsewhere.

12.8W/mK conductivity drives the purchase decision

The single specification that decides fit is the 12.8W/mK thermal conductivity rating. It determines whether the paste can handle the heat load of your specific overclocked or high-wattage component. Verify your cooler mounting pressure and die size match typical enthusiast usage before buying.

Questions about this item

What cooler or heat-sink do I already need to use this 12.8W/mK paste with my CPU or GPU?

You need a compatible CPU or GPU cooler with a flat mounting surface; the paste fills microscopic gaps between the die and that cooler base.

Will this 4.0g syringe work on an older processor that previously used a lower-conductivity compound?

Yes, it is non-conductive and rated from -50 to 250 °C, so it replaces older pastes on legacy CPUs or GPUs without electrical risk.

How can I verify the paste is applied correctly after following the centre-dot and scraper steps?

The layer should be roughly the thickness of an A4 sheet; a drop in load temperatures compared with the previous compound confirms good contact.
