High-conductivity paste for CPU and GPU

Maxtor CTG8 thermal compound delivers a rated thermal conductivity of 12.8W/mK in a 4.0g syringe. It is formulated for processors and graphics cards that run hot under heavy workloads. The paste suits builders who need reliable heat transfer between die and cooler. It is not for users who require electrically conductive liquid metal or larger volumes for multiple builds.

Consistent spread under continuous load

The compound remains stable and does not volatilise easily during extended gaming or rendering sessions. Its viscosity allows a uniform layer roughly the thickness of an A4 sheet after mounting pressure is applied. This behaviour helps maintain steady temperatures when the system is stressed for hours. It is not for applications that demand phase-change pads or pre-applied factory films.

Wide temperature range with low maintenance

The product operates from minus 50 to 250 degrees Celsius, covering typical desktop and high-TDP scenarios. Because it resists drying out, thermal resistance stays low without frequent re-application. The non-conductive formula avoids short-circuit risk if excess spreads beyond the die. It is not for sub-ambient cooling loops that require specialised cryogenic pastes.

Questions about this item

Will the 12.8W/mK conductivity keep temperatures low during all-day gaming?

The 12.8W/mK rating supports efficient heat transfer from CPU or GPU dies, helping maintain lower temperatures under sustained high-TDP loads.

What tools do I need to apply the 4.0g syringe paste?

You need a clean CPU or GPU surface, isopropyl alcohol for cleaning, and a scraper or spreader to achieve an A4-paper-thin layer.

Can this paste stay stable on an older cooler that runs hotter than modern ones?

The compound remains stable from -50 to 250 °C and is non-volatile, so it will not dry out or degrade on legacy coolers running at higher temperatures.
