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 und 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

Suitable for compressor cooling

NT-H1 is perfectly suited for use with compressor coolers. Even at the very lowest temperatures, the paste delivers full performance and remains easy to clean off.

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

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

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

Som vi ser ut av grafen så vinner Noctua en knepen seier over Innovative Cooling. Det er ikke snakk om mer enn 2 tideler, men Noctua er vinneren.
Test verdict: "Det er den anerkjente produsenten Noctua som har satt sammen den beste varmeledende pastaen du får tak i her i Norge." (Jørgen Elton Nilsen, Hardware.no)

NT-H1 Review

As you can see, at idle state Noctua’s NT-H1 paste is marginally lower than the GC1 compound but is roughly the same. However, at load state there is a bigger difference (0.5°C). This may not sound particularly big but this is fairly significant as thermal compounds simply transfer heat from the CPU to the heatsink by helping create a good contact between the two surfaces and so any decrease in temperature is impressive. These small decreases in temperature are also particularly relevant to overclockers looking to lose every degree possible.

When compared to the OCZ Freeze, NT-H1 comes out on top at both states; this highlights the great performance of the compound and the OCZ paste is a known performer. Thus, as NT-H1 is beating well performing pastes, it must be a very good product in order to do this.
Test verdict: "Overall, this is a great product from Noctua and definitely lives up to its high reputation. Therefore, to all you overclockers and gamers I would recommend NT-H1." (Joe Blackmore, VerdisReviews.com)

NT-H1 Review

Overall the Noctua NT-H1 Thermal Compound performed very well. It did beat the Arctic Silver 5 and keept up very well in the testing, this is nothing to shake a stick at. The Noctua product was 6 degrees cooler than Arctic Silver 5 and you get more product in one tube of Noctua NT-H1 Thermal Compound then an equivalent priced tube of Arctic Silver 5.
Test verdict: "The Noctua NT-H1 Thermal Compound did better than many other compounds I have used in the past. I was very impressed with its overall performance and it was very easy to apply" (Justin Desjardins, OverclockersHQ.com)

NT-H1 Review

NT-H1 is the clear temperature champ here, with a 1.5 C drop in peak temp and a faster drop to a stable temperature. Very impressive!
Test verdict: "Noctua's list of features for this paste couldn't represent the product any better. It has excellent performance, is easy to install, has no burn-in time, and is not electrically conductive." (Andrew Schembri, Mikhailtech.com)

NT-H1 Review

If we have to declare a winner of course it would be the Noctua NT-H1, but the temperatures are extremely close all around, and to make a choice you'd have to consider price and quantity you'd receive for that price. Considering you get quite a bit with the NT-H1 for a low price (about $8 average) it's well worth the cost in terms of performance and quantity.
Test verdict: "Obviously, from my testing, Noctua has a great product in their new NT-H1 thermal compound, it offers instant thermal conductivity, which translates to great performance from the minute you apply it. NT-H1 has many other features going for it as well, including being non-conductive, long shelf life, long usage time, large quantity and a low price, all of these things combine to make an excellent product that in the highly competitive market will be hard to beat."

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)
