Thermal paste Noctua NT-H1 10G

Noctua NT-H1 is a hybrid thermal compound that combines high thermal performance with long-term stability and ease of use. Supplied in an extra-large 10 g syringe, it is suitable for both CPU and GPU cooling in air- and water-cooled systems and is widely used by overclockers and system builders for reliable heat transfer.

Advantages

NT-H1 has award-winning thermal performance validated by independent hardware reviews and has been bundled with Noctua coolers since 2007. The compound spreads well without manual distribution, is simple to clean with a dry then moist tissue (no solvents required), and is non-electrically conductive and non-corroding, making it safe to use with copper or aluminium heatsinks. Its formulation ensures excellent long-term stability: it can be stored at room temperature for at least three years and remain effective on a CPU for five years or more. The paste requires no break-in or burn-in period and the 10 g package supports multiple applications.

Suitable for

• CPU cooling (air and liquid)
• GPU cooling and heatsink rework
• Overclocked systems and high-performance builds
• Silent/low-noise systems

Key specifications

How to use

Apply a small amount of thermal paste to the centre of the CPU heatspreader, then mount the heatsink and fasten it according to the cooler manufacturer’s instructions. NT-H1 spreads evenly under pressure so manual spreading is not necessary. For larger surfaces (e.g. TR4), use a slightly larger amount; for small CPUs (e.g. LGA1151) use a smaller dot. After removal, wipe off excess paste with a dry tissue, then clean remaining residue with a moist tissue.

Usage recommendations

Store the syringe at room temperature and avoid direct sunlight. One 10 g package is sufficient for multiple applications (approx. 9–60 applications depending on CPU/GPU size). Do not use solvents for cleaning; follow standard ESD precautions when working on system internals.
