Description

Noctua's premium cooling components are internationally renowned for their superb quietness, exceptional performance and quality. Visit the Store Visit the Store Visit the Store Visit the Store Visit the Store Visit the Store Visit the Store NT-H2 is the further improved second generation of Noctua’s award-winning hybrid thermal compound. Combining the iconic NT-H1’s proven features, superb ease-of-use and renowned long-term stability with a novel, fine-tuned formula of micro particles for even better thermal performance, NT-H2 is an enthusiast-grade paste for the highest demands. Whether it’s air- or water-based cooling, CPU or GPU applications, overclocking or silent systems: NT-H2 will consistently deliver outstanding results and thanks to the included cleaning wipes, it is just as easy to remove as to apply. The AM5 Edition also includes the NA-TPG1 thermal paste guard that prevents thermal paste build-up in the cut-outs of the heatspreader of AMD AM5 CPUs – a simple yet highly effective means to keep your AM5 processor clean. When the mounting pressure of the cooling solution is applied, excess thermal paste will be squeezed outwards. With AM5 CPUs, this excess paste tends to accumulate in the cut-outs at the sides of the heatspreader and may become difficult to remove. Simple to apply, the NA-TPG1 prevents this undesired phenomenon. The 3.5g pack of NT-H2 includes three large NA-CW1 cleaning wipes that are pre-moistened with an isopropyl alcohol mixture and make it child’s play to remove: Simply wipe off the paste from the CPU and the base of the cooler using one of the wipes and you’re done! While some high-end thermal compounds and pads are risky to use due to their electrical conductivity or corroding properties, there’s no risk of short-circuits with NT-H2 and it’s completely safe to use with any type of CPU cooler, regardless of whether it’s made from copper or aluminium and whether it’s nickel-plated or not. NT-H2 unique formula is highly stable over time, even after longer periods of usage. It can be stored at room temperature for at least 3 years and due to the compound’s exceptional curing, bleeding, dry-out and thermal cycling characteristics, it can be used on the CPU for 5 years or more. Sufficient for around 3-20 applications (depending on the size of the CPU or GPU, e.g. around 3 applications for large CPUs such as TR4, 15 for AM4/AM5 or LGA1700, and around 20 for small CPUs such as LGA1151), the classic 3.5g packaging size is ideal for most users who only install coolers every now and then. Thanks to its excellent spreading properties, there is no need to manually spread NT-H2 before installing the cooler: Simply apply some paste onto the CPU (see instructions for details), put on the heatsink and you’re ready to go!

  • Worth the cost and effort to replace the thermal paste!
The product works very well as you will see in the post replacement thermal metrics. The target PC was put into service in August of 2021 and this is the first CPU thermal paste replacement. I’m so pleased with the lower CPU package temperature that I’m going open the case again and replace the GPU thermal paste as well for this AIO liquid cooled CPU/GPU 10L case B550 ITX R9 5950X / nvidia 3880 gaming PC. ... show more

  • Excellent paste
Disclaimer: I am reviewing this product from the perspective of a normal system that is not overclocked. I do not build, test, or use overclocked systems. I have used Arctic brand thermal paste for most of my PC building career, which is fantastic and I would never turn anyone away from using it. I have mostly switched to Noctua NT-H1 and NT-H2 for the sole reason that it spreads very easily. I have tested the paste by putting a medium sized blob in the center of the processor then installed the heatsink. After removing the heatsink, I can see the paste has spread evenly across the processor face, which is incredibly convenient. No more fighting to get paste evenly distributed using a toothpick or card. As far as performance goes, this works just as well as the Arctic stuff, and any difference is within a degree or 2. I cannot say if this holds up as well under extreme OC situations, as I do not use it for that purpose, there is plenty of information out there by professional overclockers that surely answer that question. TLDR - Get this or the NT-H1 if you hate manually spreading paste and just want a good product for building your next gaming (or work) PC. ... show more

  • Great Noctua Product
Great Noctua product, dropped my CPU temps by 2-3 degrees.

  • Guard smaller than expected
I know my cpu isn't gigantic but I thought the included guard would be a big bigger? Very small and flimsy. I don't doubt Noctua's quality but I opted to use a contact frame instead. Paste seems good so far though

  • Near perfect product….
Item was amazing, easy to clean up and install. Only downside is mine was missing the AMD heat spreader template.
