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 10g pack of NT-H2 includes ten 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.
Extra-large 10g package for 9-60 applications
Sufficient for around 9-60 applications (depending on the size of the CPU or GPU, e.g. around 9 applications for large CPUs such as TR4 and around 60 for small CPUs such as LGA1151), the extra-large 10g packaging size is ideal for power users who install coolers frequently.
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!

Great replacement for my aging kryonaut while being much cheaper and achieving lower temps.

It's Noctua thermal paste. You are getting exactly what you expect. Great quality from a long standing Leader in the game. Wipes are nice for getting the old crusty paste off. Good size tube should last a while. Versatile for use on graphics cards as well. Gives temperatures you expect when applied correctly.

This stuff is really nice. My temps are a few degrees cooler and the paste is easy to apply with the tube. I also like the included wipes for cleaning the CPU before application.

Excellent quality and performance, and comes with 10 wipes to clean thermal compound residue. Very much worth the price.

Average load temps went down 4-6C compared to Arctic MX-6 thermal paste. Max load temps went down 4C. 14900KF with a Be Quiet Pure Loop 2 360mm AIO. Enough said. This paste is definitely some of the best on the market. If you buy it, you will not have to worry about getting bad temps with your cooler.

Tackier than NT-H1, but thermally better.Buy with confidence. There's probably only Kingpin paste that is better. I personally had a bad experience with Kryonaut, when temps soared after only a few weeks/months. Apparently that was a well known problem and fixed by Thermal Grizzly.NT-H1 and H2 lasts however, and is thermally equal to or better than Kryonaut. Better in my opinion.

Applied on Acer Predator Helios 300 and CPU and GPU temps dropped by 10-15 degrees, does it's job well and easy to apply, also plenty of wipes in the box.

I have been refurbishing cherished computers. A major part of that is to clean out all the dust and clean and reapply the thermal paste and pads. This is the paste I use for every rebuild because it is what I use on my own computers. The one downside to this packaging is the dispenser hides the quantity remaining, so you really have to make sure you always have an unopened spare. Lesson learned. Once you are out of paste or pads, the work grinds to a halt.I'd recommend a simple opening in the label at the applier end. I will be removing my label ends in the future.

Auf der Suche nach der perfekten Wärmeleitpaste für meinen PC bin ich auf die "Noctua NT-H2" gestoßen.Die Wärmeleitpaste wird in einer sicher verschraubbaren Spritze geliefert, sodass diese gut vor dem Austrocknen geschützt wird. Zudem werden in der 10g-Variante 10x Reinigungstücher beigelegt, damit man die Flächen am Kühler bzw. CPU/GPU gut vorbereiten kann.Im direkten Vergleich zur "Thermal-Grizzly Kryonaut Extreme" erziele ich nun mit der "Noctua NT-H2" 6°C niedriger auf meinem Intel Core I7-12700K.

TL/DR - Spreads great. Excellent temps. Non-conductive. Trusted Noctua brand. Excellent value in 10g tube. It’s thermal paste… Buy it!——————FULL REVIEW…Ahh thermal paste… arguably the most overthought & debated aspect of PC building, yet probably the least important thing to worry about. “How much do I use??? Should i use a pea-dot? X pattern? Spread it with a credit card???” Answer to all of these = Yes. Seriously - if nothing else, just put some paste on the processor and drop the heat sink… it’ll work fine. Noctua does however include a manual with this paste that will provide recommended application techniques for each processor type (various intel sockets, Ryzen, Xeon, threadripper). Plenty of quality tests show the difference between the “best and worst” pastes and application techniques is at most 5*C. That being said… I really do like this paste. It appears to be a nice upgrade from the very reliable NT-H1 that I’ve used for years. It’s non-conductive, so no worries about frying something. I used the AMD & Noctua recommended “five dot method” (Pea-Dot in the middle, plus four smaller dots more near the corners) for my new Ryzen 5900x under a Noctua NH-D15. These Ryzen 5000 processors can run pretty warm, but I’m extremely pleased with the temps… 63*c max for cinebench r23 & never over 70*c while gaming (all of this on warmer days mind you). I love the fact it comes in a 10g tube - it’s a wonderful value for the amount included. The included cleaning wipes are a nice touch and will probably be appreciated by some.This is definitely my new go-to paste and I’ll be recommending this 10g tube to anyone who needs a good amount for future uses as well! Thank you Noctua for continuing to be my most trusted brand for most things cooling!

Un producto muy bueno, la he aplicado en dos laptops, la eficiencia es muy genial, ya no suena como turbina de avión, ni al jugar se calienta mucho, con juegos GTA V, Bourdenland 2, Metro 2033 y saliendo del juego bajan los RPM del ventilador.Por la relación precio con y sin, toallas con alcohol isopropílico, vale la pena, pagar un poco mas por ellas. si es que no quieres comprar el alcohol isopropílico aparte.

The price for this thermal compound is arguably high. But, Noctua never tries to have the cheapest product and Noctua is famous for including extras. In the box, you get a giant tube of thermal compound, several cleaning wipes, and a very handy diagram. Noctua claims there is no need to spread their compound, but they do recommend a variety of patterns to get the best coverage depending on the size of the heat spreader.I have used so many thermal compounds in the past ranging from those included with cooling products up to expensive compounds. They all perform close enough together that you’d barely notice the difference. Ease of application and longevity should be what you look for in a compound. Noctua is easy to apply as it doesn’t require spreading and will last 5 years before it dries out and you see any performance loss. If that 1 or 2 degrees does matter to you, the Noctua compound usually lands near the top of professional reviews.If you found my review helpful, please press that button.
