Product Description


NT-H2 is the further improved second generation of Noctuas award-winning hybrid thermal compound. Combining the iconic NT-H1s 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 its 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 childs play to remove: Simply wipe off the paste from the CPU and the base of the cooler using one of the wipes and youre 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, theres no risk of short-circuits with NT-H2 and its completely safe to use with any type of CPU cooler, regardless of whether its made from copper or aluminium and whether its 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 compounds 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 youre ready to go!

- Reviewed in Canada on December 18, 2024Verified PurchaseIve 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 products quality and performance.
If youre 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. Its well worth the investment and a product Ill continue to use in the future.
- 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 5C 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!
- 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 30C when most people have around 45C with factory paste and an hour of afterburner stress test only brought GPU temperature to sub-60C 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 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 July 9, 2025Verified PurchaseRTX 3080 was overheating, replaced the old crusty paste and got temps from 95c throttling to 75c stable. Otherwise, paste is paste. Noctua has always been a real reliable brand.
- 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 February 26, 2025Verified PurchaseGot the 3.5g and repasted my CPU and have lots left for later use.
Cleaning wipes were awesome to have and work great.
Temps are lower then stock paste.
Would buy again this stuff is awesome.
- Reviewed in Canada on February 26, 2024Verified PurchaseI must say that the Noctua NT-H2 Thermal Paste has exceeded my expectations in keeping my new computer remarkably cold even under stress test. I anticipated my Intel Core i7 12700k to heat up during intense tasks or during my benchmarks but thanks to this thermal paste, temperatures remained impressively low.
The 3.5g tube provides ample paste for multiple applications, and the inclusion of 3 cleaning wipes adds to the convenience since since most of pc builder including my self remove the already applied thermal paste of their CPU cooler to put better and more fresh one. The application process is straightforward, and the paste delivers efficient heat transfer according to all the test I did, ensuring optimal performance for my processor.
Therefore, the Noctua NT-H2 Thermal Paste is the way to go to maintain good temperature for your PC.

Verified Purchasellevo bastante tiempo con esta pasta trmica, es muy buenas ya que puede bajar 1 o 2 grados mas que otras pastas trmicas lo que me hizo comprarla es que viene con sus toallas de alcohol isoproplico que con una basta para limpiar el sistema de refrigeracin que en este caso es una asus tuf f15, RECOMIENDO cambiar la pasta trmica segun el uso que le des ya sea esta pasta trmica o otra, solo infrmense bien sobre la conductividad trmica de la pasta
