Product Description

NT-H1 3.5g SW Edition header

Noctua’s NT-H1 is a renowned hybrid thermal compound that has received more than 150 awards and recommendations from international hardware websites and magazines. Thanks to its excellent performance, exceptional ease of use and outstanding long-term stability, it has become an established favourite among overclockers and enthusiast users worldwide. Whether it’s air- or water-based cooling, CPU or GPU applications, overclocking or silent systems: NT-H1 is a proven premium paste that’s guaranteed to deliver great results.

1

Award-winning performance

Bundled with Noctua’s premium-grade CPU coolers since 2007, NT-H1 has proven its excellent performance in countless of tests and reviews. Chosen again and again by overclockers and hardware enthusiast around the globe, it has established itself as a benchmark for premium-quality thermal interface materials (TIMs).

NT-H1 SW Edition Spatula

Easy to clean

NT-H1 is one of the easiest to clean thermal compounds on the market: Simply wipe it off the CPU and heatsink with a dry tissue or paper towel, then wipe them clean with a moist tissue or towel. No cleaning alcohol or solvent required!

Non-conductive

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-H1 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-H1's 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.

NT-H1 SW Edition

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.

1

Easy to apply

Thanks to its excellent spreading properties, there is no need to manually spread NT-H1 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!

5 out of 5 stars
Easy to use
The thermal past arrived in a sealed box that appears to be tamper resistant. NT-H1 spreads a bit easier than NT-H2, and the 3.5g dispenser is enough to do quite a few computers and game consoles. It really doesn't take much. There are QR codes for instructions, and this paste spreads sufficiently that I believe users will find it a joy to work with. Noctua is a good brand, I've used their NF-P12 120mm and 60mm fans. The hydro oil bearings last almost forever and the motors don't whine.

    I used the Noctua NT H1 thermal paste for my first computer build, and it has been working perfectly ever since. More than three years later, my temps are still stable with no issues. Application was easy, and it spread well without making a mess.

    I recently used this pro-grade thermal compound paste for my PC build, and I’m extremely impressed with the results. The application was smooth and easy, allowing me to spread it evenly across the CPU surface without any hassle.

    After installing everything, I noticed a significant drop in temperatures compared to the previous thermal paste I used. My CPU runs cooler and more efficiently, even under heavy loads, which gives me peace of mind during gaming and intensive tasks.

    The consistency of the paste is perfect—not too thick and not too runny—making it ideal for optimal heat transfer. I also appreciate that a little goes a long way, so the tube should last through several builds.

    Overall, I highly recommend this pro-grade thermal compound paste to anyone looking to improve their cooling performance. It’s a great investment for keeping your components running smoothly!

    This is an excellent product in an equally nice dispenser. Used this to add some heat transfer paste for the switch lite after reassembly. The old thermal compound was dry and flaky, but it's simply good practice whenever you service systems and remove and replace thermal transfer parts. This thermal paste is very easy to apply and it spreads well. Not too greasy or too liquid. Maybe a little expensive compared with purchasing at a local computer or electronics store, but I didn't want to go digging around the city for it.

    I’ve used this paste for my last two PC builds, and it’s been great both times. The consistency is smooth and easy to spread evenly, and temps have stayed low under load. It doesn’t require a huge amount either, so one tube lasts a good while. I like that it’s non-conductive, so there’s no stress if you accidentally apply too much. Not the cheapest, but worth it for peace of mind and performance.
