Noctua NT-H2 10g, High-Performance Thermal Paste and 10 Cleaning Wipes

The Noctua NT-H2 10g Thermal Compound (with 10 cleaning wipes included) is one of the best thermal pastes I've used in recent PC builds and upgrades. Pros: Outstanding thermal conductivity — It delivers temps that are often 2–5°C better than stock paste and very competitive with (or sometimes beating) premium competitors like Kryonaut or Thermal Grizzly options in real-world use. On my 7950X, it helped keep all-core loads in the mid-70s under a decent air cooler where previous pastes pushed into the low 80s. Long-term stability — Noctua claims no pump-out or drying issues over years, and from what I've seen in systems running 12+ months, it holds up without noticeable degradation. No cracking or separation I've observed. Super easy application — The viscosity is just right: spreads nicely with pressure but doesn't run like liquid metal. No need to manually spread it — the classic "pea-sized blob" method works perfectly every time. Includes 10 NA-CW1 wipes — These are legitimately useful pre-moistened isopropyl wipes that make old paste removal clean and quick without leaving residue. Saves buying separate cleaner. Non-conductive and safe — No risk if you over-apply slightly, unlike some liquid metal alternatives. Minor cons / things to note: It's not the absolute lowest-temperature paste on the market if you're chasing extreme overclocking bench records (some hybrid or special pastes edge it out by 1–2°C in synthetic tests), but for 99% of users — gaming, productivity, silent builds — the difference is negligible. Price is a bit premium compared to generic pastes, but you get what you pay for in consistency and longevity. The 10g tube lasts for many applications (I've done 6–7 full CPU + GPU pastes from one tube so far). Overall, 5/5 stars from me. If you're looking for a "set it and forget it" thermal paste that performs at a high level without drama, NT-H2 remains one of the top choices in 2026. Highly recommended for anyone building or maintaining a serious PC. Noctua nailed it with the second-generation formula.

If you’re doing a proper computer build or rebuild, this is one of those products you don’t gamble on. Noctua NT-H2 delivers exactly what you want from a premium thermal compound: excellent thermal performance, long-term stability, and zero drama during installation. Application is easy and consistent, with no need for spreading, curing, or burn-in time. Temps are immediately stable under load, and it performs reliably across CPUs and GPUs with both air and liquid cooling. It’s non-conductive, non-corrosive, and designed to last for years without drying out or pumping out. The included cleaning wipes are a genuinely useful bonus—great for clean removals and reapplications without hunting down extra supplies. Packaging and instructions are clear, with recommended application patterns that make it easy to get it right the first time. This is one of those “buy once, use forever” items for anyone who regularly works on PCs. Reliable, predictable, and built for long-term performance, exactly what you want from a top-tier thermal paste.

Do not sleep on this stuff, my Lenovo L14 G4 Ryzen 5 consistantly peaks 4600mhz over the OEM 3900mhz with OEM paste at full tilt, the cooling solution in these laptops are much more capable then nessassery and throtteling is reduced a lot with the increased thermal transfer at this point alone. for light to medium work i never hear the fan reach high then 25% fan speed due to this and a quiet laptop is a blessing for sure. The tube size is much larger then anticipated and has pasted 15 devices so far.

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!

I used to use the old arctic silver back in the day and this has far surpassed the performance of that, not to mention that I have to replace it less often

Only thermal compound I use. Last for years and has been proven time and time again as a top thermal paste. Highly recommend.

For the money it’s really good. Temperature control is better than other brands 1 to 2 degrees cooler than competition. 10g is a lot for the money you pay. For the size of the tube you get and only using a pea sized portion it will last you awhile as long as you keep it properly stored.

The thermal paste worked like a gem. I did a ton of research before purchasing to make sure it was the best. I applied it about two years ago to my custom PC and only recently started having overheating issues which may or may not be due to the thermal paste needing replaced. If it is it's possible that I just left the CPU cooler out just a little too long before applying then attaching the CPU cooler to the CPU. Normally it should last a lot longer if applied properly. It runs my system extremely fast though. I have a very high end system that demands a lot so it does the job well in that respect. It doesn't come out too much at once if you know what your doing and have experience or have read up properly on how to apply thermal paste to your CPU. Noctua is a fantastic brand that I couldn't recommend enough. Again it might have been my error that I'm having the heat issues I'm having where the thermal paste may have dried up over time, but I'm not sure.

Bütçeniz varsa kesinlikle alın bunu; miktarı yüksek. Isı iletkenliği ( W/mK ) belirtilmiyor ama çok yüksek. Cıvıklığı bir tık fazla ama kontrol edilemez değil. Eski bir macundan kalan bir yayma kaşığı vardı maalesef bunun kutusundan öyle bir şey çıkmıyor, onun sayesinde neredeyse kusursuza (ince ve dümdüz) yakın dağıtabildim. İçinden 10 tane ıslak mendil çıkıyor ama bu mendiller sadece soğutma bloğu için; bunu unutmayın. Resim koymadım çünkü ürün görseliyle birebir aynı. '' X derece kadar ısıyı düşürdü'' diye net bir kıyas yapamam bundan önce de iyi bir macun kullanıyordum yatay geçiş gibi oldu, kasa değiştirdiğim için ihtiyaç oldu ve hiç pişman değilim. Kusursuz havalandırma kombinasyonu yakalarsanız bilgisayarı kurarken bu macun ciddi fark ettirecek, PC en baştan ısınmayacak.

This paste works extremely well. It keeps my Ryzen 9-5900XT running cool (31C on idle, 45C-55C during games and the most at 62C when doing AI rendering). I am using an AIO (water cooling kit) so that helps as well. But the paste is non conductive, so if it spills over to your components on the MB it wont short it out (some pastes use metal in their paste which will short out your MB if there is spillage). Easy to apply as well and enough (the 10g one I got) for multiple use. The main thing with good paste is how well it will hold up over time (unlike thermal pads which dont degrade over time, which also works very well), many paste over time just burn away and dont cover the CPU as good and you have to reapply after a year or so as your temps go up. I applied this paste the first time and used it for a month and had to remove my CPU AIO and even after running my CPU a while to heat up the paste it still held onto my CPU cooling plate really good. I reapplied and it has been running the same temps for the last few months with no problem. But I have used cheaper pastes and after a month or so the temps changed a bit at a time and after a year I had to reapply but what I have seen thus far with this paste is it should hold up well for years (I tend to reapply paste after 2-3 years regardless), but the paste quality of this product seems very good and a lot of science went into developing it. It will not disappoint.

As advertised great product

Muy buena pasta térmica calidad precio. Rendimiento espectacular en gran cantidad

Facile à mettre en place, même pour quelqu'un qui n'avait jamais démonté un ordinateur. Juste bien suivre les instruction pour en mettre assez, mais éviter que ça déborde. On voit bien la différence de température, je suis contente d'avoir choisi cette marque réputée.
