Details
Excellent performance

Excellent performance

NT-H1 consists of a hybrid compound of different micro-particles, which has been specifically optimized for use in PC environments. Thanks to its extremely low thermal resistance as well as excellent pliability and spreadability, NT-H1 achieves outstanding results.
Maximum ease of use & efficient dosage

Maximum ease of use & efficient dosage

As NT-H1 spreads very well under pressure, there's no need to smear it over the heat-spreader. This reduces both the consumption of paste and the time spent on the installation process: Put one drop of NT-H1 onto the centre of your CPU, install the cooler and that's it!
Top-performance right from the start

Top-performance right from the start

NT-H1 reaches its full performance extremely fast and doesn't require a longer "burn-in" time.
Excellent long-term stability

Excellent long-term stability

NT-H1 doesn't contain any solvents or other substances with low flash point and provides excellent long-term stability. Due to the compound's exceptional curing, bleeding, dry-out and thermal cycling characteristics, NT-H1 can be used for several years without any problems.
Not electrically conductive, non-corroding

Not electrically conductive, non-corroding

NT-H1 possesses a very low dielectric constant and a high dielectric strength. Therefore, there's no danger of short-circuits even in case of direct contact with components or conducting paths. Fully compatible with all materials commonly employed in PC environments, NT-H1 is suited for use with aluminium and copper coolers.
Suitable for compressor cooling

NT-H1 Review

For first place, this was a close run all the way through testing. Both of these thermal pastes performed very well. They performed so well during testing, that these two companies kept bouncing between 55°C and 56°C, Gelid's GC-1 and Noctua's NT-H1.
Test verdict: "This thermal Paste was one that took me completely off guard. After seeing temperatures anywhere from 57-70+°C on my CPU, I was not expecting this thermal paste to do any better than what I was seeing. This thermal Paste not only took first place (shared with Gelid GC1), this thermal paste did this with style. NT-H1 gets a hard earned 9.5 out of 10" (Raymond Buckland, Bjorn3d.com)

NT-H1 Review

Well, I wasn't expecting much different at stock speed and voltage, but then again, I haven't used half of these thermal pastes on a CPU before. I was surprised by the difference in load temperatures of the Noctua NT-H1 compared to the worst in the group, the Vantec thermal paste, 6°C difference just from thermal paste! The gap widens when overclocked and overvolted, and while the NT-H1 is neck and neck with the AS5 at stock, the NT-H1 takes the lead when the CPU is producing a massive heat load. The next nearest thermal paste after AS5 is Thermalright's 'Type 2,' which results in a 4°C higher load temperature. The other pastes in this review are even worse, with the Vantec paste giving a whole 11°C higher load temperature!
Test verdict: "I wasn't expecting the Noctua NT-H1 to outperform Arctic Silver 5 (AS5) during the tests, but it did when the system was overclocked and producing the highest heat load" (Steve Goossens, OverclockersClub.com)

NT-H1 Review

The Noctua NT-H1 thermal compound was a pleasure to work with. It was easy to apply and the performance was great right from the start. No burn-in time was needed with the NT-H1, unlike Arctic Silver products.
Test verdict: "If you are in the market for some new thermal compound, I suggest checking some Noctua Nt-H1 thermal interface material out for yourselves." (Todd Kracinski, techPowerUp!)

NT-H1 Review

It seems like lately, all of the newer thermal compounds we have tested perform extremely close to one another. The NT-H1 is no different since it performs well but what really stands out with this product is how easy it can be cleaned from your processor. This is just another in a long line of high-performance Noctua products and once again we have to say that Noctua really should be proud of themselves.
Test verdict: "We have to say Kudos to Noctua for designing a great thermal compound." (Prof. Dr. Silver, HardwareCanucks.com)

NT-H1 Review

Tras haber probado la pasta térmica Noctua NT-H1 en nuestro procesador, podemos decir, que este producto presenta una buena textura para ser aplicado con facilidad mediante su jeringuilla, la cual podemos tapar para evitar que se estropee. En las pruebas hemos obtenido buenos resultados, con lo que la Noctua NT-H1 transfiere de forma exitosa el calor entre el procesador y el disipador, evitando que se sobrecaliente el procesador. Además, también hemos comprobado que esta pasta térmica se puede utilizar perfectamente en Overclocking, permitiéndonos así subir las capacidades del procesador por encima de lo normal sin que éste sufra mucho. Y además, cabe indicar que la pasta térmica Noctua NT-H1 tiene un “tiempo de cura” muy bajo, y si se cuida, puede ser bastante duradera.
Test verdict: "Con todo ello, creemos que la pasta térmica Noctua NT-H1 es un buen producto para ayudarnos a refrigerar nuestro PC por poco dinero, y por ello le otorgamos nuestros premios de calidad/precio y de recomendado." (Isabel Fernandez Aldariz, HardManiacos.com)

NT-H1 Review

Mit der NT-H1 Wärmeleitpaste bietet der österreichische Kühlerspezialist das adäquate Zubehör für ihre eigene Produktlinie an. Die Paste machte während der Tests eine sehr gute Figur und präsentierte sich durchweg positiv. Sehr gute Handhabung und Verteilbarkeit, zeichnen dieses kleine unabdingbare Utensil aus. Auch leistungstechnisch präsentiert sich das Noctua Produkt von der besten Seite. Die schon sehr gute Prolimatech MK-1 wird sogar noch marginal übertrumpft.
Test verdict: "...eine sehr gute Wärmeleiste die ohne Kompromisse das macht, was sie soll." (Marcel Büttner, HW-Journal.de)

NT-H1 Review

From the results above we can see that Noctua's NT-H1 provides consistently better heat transfer at idle and load temperatures than AS5. Sure AS5 requires around 200 hours to cure properly and temperatures will drop steadily during that time, but NH-1 manages to do it straight out of the syringe.
Test verdict: "I must admit that I was really impressed by the Noctua NT-H1's performance today. NT-H1 was very easy to apply; demonstrated a better stability than the other greases and provides very satisfactory results straight out of the syringe." (Matthew Fogg, Overclock3D.net)

NT-H1 Review

We have seen here that in the case of the compounds we have here, the H1 was clearly the better grease. But it just barely beat out the Arctic Silver 5. But the others pretty much didn't stand a chance.
Test verdict: "The Noctua H1 is a great replacement to the once-king Arctic Silver. When it comes to getting the mostly out of your overclocks and keeping the lowest possible temp one degree can mean a lot. And that is how much the H1 beat the A.S. 5 by." (Tony Walker, Pro-Clockers.com)

NT-H1 Review

L'installation de la NT-H1 fût très simple. La pâte thermique est normalement épaisse et de couleur vaguement grise. Il suffit donc, après un nettoyage consciencieux du processeur (un simple chiffon doux sec ou imbibé d'alcool à 90°), de mettre la nouvelle pâte thermique. On la place sous forme d'une sorte de boule au milieu, et la pression du Noctua lors de son montage fera le reste. Pas besoin de vider la seringue.
Test verdict: "NT-H1 est un véritable transmetteur de Watt. Au vu de son prix inférieur à 8 € et de la longévité de conservation et du nombre d'utilisations possibles, elle devrait faire partie intégrante de toute trousse de montage de PC." (Jean-Baptiste Schmitt, ZeDen.net)
