Based on the award-winning NT-H1

Based on the award-winning NT-H1

NT-H2 is based on Noctua’s renowned NT-H1, which has received more than 150 awards and recommendations from international hardware websites and magazines. Chosen again and again by overclockers and enthusiast users worldwide, NT-H1 has established itself as a benchmark for premium-quality thermal interface materials (TIMs).
Next-generation performance

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 apply

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!
Easy to clean with included wipes

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!
Optional NA-SCW1 set for power users

Optional NA-SCW1 set for power users

Power users who take off and install their coolers frequently can purchase the optional NA-SCW1 set that contains 20 pieces of the NA-CW1 cleaning wipes, which are ideal for removing NT-H2 from the heat-spreader of the CPU and the contact surface of the heatsink.
Not electrically conductive, non-corroding

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

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.
No break-in or burn-in required

No break-in or burn-in required

Some thermal compounds need a longer break-in period or cure time until they reach their full performance and some thermal pads must undergo a dedicated burn-in process. By contrast, NT-H2 is ready to go right away and doesn’t require any special preparations.
3.5g package for 3-20 applications

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.

NT-H2 3.5g Review

Con la excusa del reciente lanzamiento de las pastas térmicas Noctua NT-H2 y Corsair TM30, hemos decidido analizar el rendimiento de nada menos que 9 compuestos térmicos, buscando entre ellos cual es la mejor pasta térmica, así como el más rentable.
Test verdict: "Como podemos ver en la gráfica anterior, la ganadora de nuestra comparativa de compuestos térmicos no es otra que la nueva Noctua NT-H2, abriéndose un abanico de hasta 10º de diferencia con el peor de sus rivales." (Iván Martínez, El Chapuzas Informático)

NT-H2 3.5g Review

Noctua bietet mit der NT-H1 seit Jahren ein und dieselbe Wärmeleitpaste an. Das beschreibt stellvertretend die Gesamtsituation im Wärmeleitpastenbereich. Innovationssprünge sind zumindest bei konventionellen Wärmeleitpasten kaum zu erwarten. Und alternative Lösungen wie Flüssigmetallpasten oder Kohlefaser-Pads sind längst nicht für jeden Nutzer und jedes Einsatzgebiet eine Alternative. Dass Noctua bei der NT-H2 als konventioneller Wärmeleitpaste noch einmal klar niedrigere Temperaturen als bei der NT-H1 verspricht, lässt da umso mehr aufhorchen. Unsere Messungen konnten tatsächlich auch bestätigen, dass die NT-H2 dieses 2-Grad-Ziel tatsächlich erreicht, ja sogar leicht übertrifft. Allerdings hat Noctua selbst schon klar eingeschränkt: Den klaren Vorteil hat NT-H2 nur auf richtig großen und hitzigen Prozessoren. Wer nur einen kleinen und genügsamen LGA 115x-Prozessor nutzt, wird zwischen den beiden Noctua-Wärmeleitpasten hingegen kaum einen Unterschied feststellen können. Als konventionelle Wärmeleitpaste lässt sich die NT-H2 unkompliziert nutzen. Sie ist weder elektrisch leitfähig noch korrodierend.
Test verdict: "Noctuas NT-H2 ist zwar eine teure, aber überzeugende Premium-Wärmeleitpaste. Gegenüber der bewährten NT-H1 bietet sie eine messbar bessere Kühl-Performance und verdient sich damit auch unseren Excellent-Hardware-Award." (Philipp Moosdorf, Hardwareluxx.de)

NT-H2 3.5g Review

Respecto a las pruebas y sus resultados, vemos una trayectoria ascendente en cuando a prestaciones, situando su NT-H1 al nivel de la MX4 y superándola en dos grados con su NT-H2. Con esta tendencia podríamos suponer que, a temperaturas mayores, obtendremos un descenso de grados algo más elevado con este nuevo compuesto. Recordemos que el banco de pruebas no es para nada del montón, con hardware de primeras marcas y rendimiento top. Finalmente debemos hablar de precios, el compuesto NT-H1 podremos encontrarlo por un precio de 8 y 15 euros en función de la cantidad, y el NT-H2 por un precio de 13 y 25 euros. La caja de toallitas saldría por unos 8 euros. Destacamos que NT-H2 incluye toallitas en el paquete, y por nuestra parte es un producto más que recomendable, aunque algo elevado en precio.
Test verdict: "Los resultados arrojan unos resultados muy similares en todas ellas, destacando sobre las demás el rendimiento de la NT-H2 a altas temperaturas, proporcionando hasta dos grados menos que las otras pastas térmicas. Así que apreciamos una mejora notable respecto a la NT-H1, la mejora de los materiales utilizados y una mayor densidad propician el intercambio de temperaturas hacia el disipador."

NT-H2 3.5g Review

Dupa cum se poate usor observa, diferentele intre cele 2 paste termice sunt foarte mici, insa se accentueaza odata cu puterea disipata de procesor cat si, posibil, cu dimensiunea suprafetei de contact, astfel ca avem o diferenta sensibil mai mare pe LGA 2066, unde suprafata de contact este mai mare dar si puterea disipata este sensibil mai mare.
Test verdict: "Noctua lanseaza o noua pasta termica ce imbunatateste produsul anterior din mai toate punctele de vedere produsul anterior. NT-H2 chiar este un demn urmas al lui NT-H1, chiar daca din punct de vedere al performantelor nu este o diferenta mare, de altfel nici nu ar avea cum sa fie o mare diferenta, pina la urma."

NT-H2 3.5g Review

Noctua has priced the NT-H2 3.5g for $12.9 and 10g for $24.9. But is the price tag justified for the second generation of Noctua’s thermal compounds? Based on our results, I have observed improvements over NT-H1. The difference of 3.14 degrees celcius from the paste alone is amazing. The NT-H2 is still little bit pricier of the two, but Noctua mentioned that they are not ending the production of NT-H1. So if you are not willing to put extra dime for this difference, NT-H1 is still available in stores.
Test verdict: "The results here clearly show that Noctua has delivered an amazing sequal to an already great product" (Athar Mahmood, Pak Gamers Republic)

NT-H2 3.5g Review

When compared with other thermal compounds, the NT-H2 performed extremely well, winning two of the three benchmarks... Being able to lower the temperature a couple degrees without switching to a bigger cooler is very impressive.
Test verdict: "If you are going to overclock your processor, it will be awesome to squeeze a little bit more performance by upgrading the thermal compound alone. The NT-H2 is definitely worth your consideration." (Chan Long Yin, Unboxing Treatment)

NT-H2 3.5g Review

I’m so impressed with this thermal paste, I’ve gone crazy. I applied it to everything that I could, including other computers in my home that barely run and barely get their CPU cooling fans to spin. Everything I applied it to resulted in significant decreases in temperatures. My greatest success story is with my Razer laptop. Despite poor Razer build quality, the laptop itself is rather impressive and has few flaws. One of its flaws, however, is its cooling solution. The Intel i7-8550U processor runs hard and creates a lot of heat. This heat just isn’t well managed by the tiny laptop cooling solution. As I brought home the laptop for an upcoming journey (currently writing this on a place for a fun fact), I decided I would reapply its thermal paste as well. Let me just say that the laptop doesn’t get nearly as hot at the top of the keyboard. In fact, I am blown away with my jaw dropped on how well the processor stays cool. While HWMonitor is reporting only a 5 – 6 °C difference from before and after, the external temperatures on the aluminum case are a huge success to me. I understand that Noctua is a company that makes a living by selling components that cool computer processors. However, even with their background, their thermal paste truly impresses me. Soon to be available on Amazon.com, I highly recommend the Noctua NH-H2 thermal paste. The performance gained from this excellent paste has me believing more and more about the importance of thermal paste.
Test verdict: "Despite using other thermal pastes in my computer building career, I plan on only using NH-H2 in the future and recommend you do the same. Especially considering its long-lasting shelf life and 5-year replacement recommendation once applied to the PC." (Justin Vendette, QWERTY Articles)

NT-H2 3.5g Review

Pour la mise en place de la NT-H2, nous avons suivi à la lettre le mode d'emploi fourni. Notre 8086k étant sur le socket LGA 1151, nous avons déposé au centre de l'IHS de notre CPU, un point de pâte thermique de 3 à 4 mm de diamètre. Pas besoin d'étaler la NT-H2, la pression du ventirad ou du waterblock s'en charge. Cette manière de poser la pâte thermique est appréciable car facile, surtout si nous comparons avec la Thermal-Grizzly Kryonaut qui nécessite d'être étalée sur l'IHS. Cette dernière étant compacte, cette opération est délicate.
Test verdict: "Ce que nous avons apprécié, c'est la méthode d'application qui est aisée et que la NT-H2 soit fournie avec des lingettes nettoyantes. Le combo des deux est juste parfait. " (Sylvain Guillotau, ZeDen.net)

How should I remove and clean NT-H2?

Use the included NA-CW1 wipes or a paper towel moistened with isopropyl alcohol to clean. If slight residues remain after cleaning with NA-CW1 wipes, you can use a paper towel or tissue to polish. However, such residues are of visual concern only and will not impair performance. Also see our video tutorial on how to use NA-CW1 wipes. If you need further NA-CW1 wipes, please purchase the NA-SCW1 set (20 pieces).

Which method of application do you recommend for your thermal compounds?

Both our NT-H1 and NT-H2 are very easy to apply and generally don’t need to be spread out manually on the CPU. However, our recommendations differ slightly from paste to paste and from CPU size to CPU size, so please refer to our product manuals and video tutorials for detailed recommendations:
  • NT-H1 manual
  • NT-H1 video tutorials
  • NT-H2 manual
  • NT-H2 video tutorials
  • Why doesn’t Noctua specify thermal conductivity or thermal resistance of NT-H1 and NT-H2?

    While there are some standardised methods for testing the thermal conductivity or thermal resistance of thermal compounds, they do not always guarantee comparable results. What's more, many vendors have started to claim thermal resistance or thermal conductivity specifications that appear simply unrealistic in the light of standardised testing. Last but not least, real world performance of thermal compounds is affected by various other factors such as spreading properties, bond line thickness, mounting pressure or contact quality, so even if there was a common and reliable industry standard for testing the thermal conductivity or resistance of thermal pastes, it would not give customers a clear indication regarding the performance they can expect. For these reasons, Noctua has chosen not to publish specifications for thermal conductivity and resistance. Taking part in a game of claiming exaggerated specifications is not an option for us and we neither want to give specifications that, in the context of this practice, could appear misleading. Instead, we prefer to let independent reviewers judge the performance of our thermal compounds versus competing solutions in order to help customers in making an informed buying decision. Please refer to our standardised comparison of NT-H1 vs NT-H2 and to our review database for independent tests.
