Pasta térmica Noctua NT-H2, pasta para dissipador 3,5 g – cinzento, temperatura de funcionamento -50–200 °C, densidade 2,81 g/cm³, volume 1,2 ml

Noctua NT-H2 is a premium thermal paste designed for CPU and GPU cooling applications. Presented in a 3.5 g syringe, the compound features a density of 2.81 g/cm³ and remains stable across a wide temperature range from -50°C to 200°C. The paste is grey, non-electrically conductive and safe to use with copper or aluminium coolers, nickel-plated or not.

Advantages

NT-H2 builds on the award-winning NT-H1 formula and delivers improved thermal performance through a refined mixture of metal oxide micro-particles that reduces thermal resistance and bond-line thickness under typical mounting pressures. It spreads easily on contact, requires no manual pre-spreading, is safe for repeated use on different cooler materials, and offers excellent long-term stability with storage life of at least 3 years and usable lifetime on a mounted CPU of 5 years or more.

Key specifications

• Density: 2.81 g/cm³
• Volume: 1.2 ml (3.5 g pack)
• Operating temperature range: -50 °C to 200 °C
• Color: Grey
• Electrical conductivity: Non-conductive
• Compatibility: Safe for copper and aluminium heatsinks (nickel-plated or not)
• Included accessories: Three NA-CW1 cleaning wipes (pre-moistened with isopropyl alcohol mixture)
• Estimated applications per 3.5 g: ~3–20 (depends on CPU/GPU size)

How to use

Apply a small amount of NT-H2 paste directly onto the CPU heat-spreader, then install the heatsink as usual; the compound’s spreading properties will create an even contact layer under mounting pressure. For cleaning, use the included NA-CW1 wipes to remove residue from the CPU and the cooler base. If you frequently remove and reinstall coolers, consider the optional NA-SCW1 pack containing 20 NA-CW1 wipes.

Recommendations

Use the included wipes to clean surfaces before reapplying paste, store the syringe at room temperature away from direct sunlight, and choose the 3.5 g pack for users who perform occasional cooler installations—power users may prefer purchasing additional NA-SCW1 cleaning wipes.
