Product Description


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.

Next-generation performance
Further improving the award-winning NT-H1, NT-H2 uses a new, fine-tuned mixture of metal oxide micro-particles for even lower thermal resistance and reduced bond-line thickness at typical mounting pressures. This allows it to achieve even better performance in most application scenarios.
Easy to clean with included wipes
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!
Not electrically conductive, non-corroding
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.
Excellent long-term stability
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.
3.5g package for 3-20 applications
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 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.

Easy to apply
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!

FROM 93+ TO 75C MAX. ALMOST 20C DIFFERENCE
Top reviews from Canada

- Reviewed in Canada on May 4, 2025Verified PurchaseWhat the title said.
So I had this laptop since 2019, and ever since then it hasn't idled at 30c and it has always throttled at 70c+ and above during gaming.
After cleaning the fans and repasting the cpu and gpu, here are the results. 30c at idle (lowest temp), and 75c max during gaming.
Needless to say I used the cooling fan i have now even before I repasted it, so I know that the 20c difference I am experiencing now is due to this thermal paste and cleaning of fans.
I should have done this years ago. Or even when I first bought this laptop. I always thought I got a defective unit due to the throttling and temps. Turns out all it needed is a repaste with a more respectable thermal paste.

- Reviewed in Canada on April 26, 2025Verified PurchaseWorked with my legion 5i pro laptop and temps are stable now.
- Reviewed in Canada on June 27, 2024Verified PurchaseUsed NT-H2 thermal paste for the new build with 150W TDP INTEL CPU. It's FANTASTIC! Combined with Scythe Fuma cooler, CPU temperature stays around 30-35 degrees C on different cores while semi-idle and never goes above 46-50 degrees C during stress tests with coolers not going beyond 50-60%.
NT-H2 has a different consistency than NT-H1 and is harder to work with. It doesn't stick to CPU lid as well and spreading it evenly is way more challenging.
I am using Noctua thermal paste - NT-H1 for years. For all the kind of CPUs (including 150Watt+ rated), GPUs and laptop chipsets. No matter what is written on the package (2 years shelf life) Noctua paste does not have REAL best before date if stored properly. I bought NT-H1 back in 2016!!!, stored it in a cool place and used again 8 years later (a couple days ago) for repasting hot ASUS ROG STRIX GPU which had factory paste completely dried out and was overheating under moderate load. 8 years old paste looks and feels the same way it did when bought new, brought idle temperature down to around 30°C when most people have around 45°C with factory paste and an hour of afterburner stress test only brought GPU temperature to sub-60°C with coolers working at less than 40%. Noctua thermal pastes are the top tier and very comfortable for working with. Arctic is also solid choice but I do not see a reason to ever use anything else but Noctua.
- Reviewed in Canada on April 15, 2025Verified PurchaseI used an AIO paste that came with it temps spiked to 95c with this paste max 80celsius Im amazed and thankful to these guys.
- Reviewed in Canada on January 9, 2025Verified PurchaseI've ordered a few tube's of this and it works well. Has kept my idle temps on my 11700k under 27c and under 70c with gaming load with a 360 Lian Li Galahad.
Recently bought a new tube for 13900k w/galahad performance 360 and the paste and was harder and not very spreadable, as it kept pulling up with the spatula and bunching. Maybe it was old or something. Still reordered another tube as I trust the product, but will be comparing to MX6. Idle temps on the questionable tube was about 40c and under load 70c on the 13900k.
Because of the performance of the application in thisbspecific instnace is the only reason for 1 star deduction.
If the new tube is spreadable and performance is like the original purchases then I will chnage my review to 5 stars.
- Reviewed in Canada on December 18, 2024Verified PurchaseI’ve used several thermal pastes over the years, but the Noctua NT-H2 has been the best by far. This paste is incredibly easy to apply, spreads smoothly, and delivers fantastic thermal performance. My CPU and GPU temperatures dropped noticeably compared to the previous paste I was using.
The 3.5g size is perfect for multiple applications, and the inclusion of 3 cleaning wipes is a thoughtful bonus that makes the process clean and hassle-free. Noctua really pays attention to detail, and it shows in the product’s quality and performance.
If you’re serious about cooling your components efficiently, this is a must-have. I highly recommend it to PC builders, gamers, and anyone needing reliable thermal paste. It’s well worth the investment and a product I’ll continue to use in the future.
- Reviewed in Canada on February 4, 2025Verified PurchaseGot the 3.5g to repaste both my laptops and have lots left for later use.
Cleaning wipes were awesome to have! (Dell loves to lather on thermal paste)
Both laptops improved in thermals, holding higher boosts longer or quieter fan on idle.
Noctua will always be a go to company for me.
- Reviewed in Canada on October 21, 2024Verified PurchaseI recently switched to Noctua NT-H2 thermal paste, and it has exceeded my expectations. As Noctua's newest formulation, the NT-H2 outperforms their previous pastes and competes impressively with Arctic MX-6. With a thermal conductivity rating of 3.5 W/mK, I've noticed a drop in CPU temperatures under load by up to 5°C compared to MX-6, ensuring better performance and thermal management.
The paste is easy to apply and spreads smoothly, creating a reliable layer that optimizes heat transfer. Plus, the included cleaning wipes make the installation process convenient and hassle-free.
Overall, Noctua NT-H2 is an exceptional choice for anyone looking to maximize cooling efficiency. If you're considering thermal pastes, I highly recommend it over Arctic MX-6 and earlier Noctua products!

5.0 out of 5 stars de las mejores del mercado
Verified Purchasellevo bastante tiempo con esta pasta térmica, es muy buenas ya que puede bajar 1 o 2 grados mas que otras pastas térmicas lo que me hizo comprarla es que viene con sus toallas de alcohol isopropílico que con una basta para limpiar el sistema de refrigeración que en este caso es una asus tuf f15, RECOMIENDO cambiar la pasta térmica segun el uso que le des ya sea esta pasta térmica o otra, solo infórmense bien sobre la conductividad térmica de la pasta
