Noctua NT-H2 10g, Pro-Grade Thermal Compound Paste incl. 10 Cleaning Wipes (10g, Gray)

Might differ from user to user but this product made significant difference in copy temp of up to -10c . Helps in maximum heat transfer and maintain temperature even under high load. I use a ryzen 7 5700x.

Firstly, loved the packaging and presentation! Regarding performance, I don't find much of a difference between my long time favorite NTH1 and Arctic MX5. It is significantly less sticky than MX5 so not ideal if you like to spread the paste manually - a non-issue for me since I always go for the "blob in the middle" application. Actually, ever since I found out about the amazing heat-resistant properties of the Kapton tape (insulating areas near the CPU/GPU heat-spreader is now simply a matter of putting a piece of tape), I have switched to liquid metal for all my computers. It is only for the non-copper heat sinks or test builds that I still use paste and for that, you can't go wrong with Noctua!

Best Thermal paste I've used till now for my laptop.

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.

Depending on the overall cooling environment and heatsink/emitting surface, results are above average to excellent. I did two 120W GPUs with the paste - skin temperatures improved by 3/6 degrees and the hotspot by 6/12 degrees, which is remarkable. After allowing for cure times and full settling after a few heat cycles, the results are superb. Application is tricky, as others have alluded to. There is quite a bit of creepage, which is a sign of fine particulate in the paste (this is good). This means that you might need to check the torque after 24 hours or so. It also means you need to add a bit of extra else you might run short. In the better case after about 6 heat cycles, the hotspot dropped from 95 degrees to 83 degrees, which is as good as a full tier upgrade. The second one has only had a couple of heat cycles and was anyway a much bigger cooler with a far better cooling arrangement (which will give less of a gain). The wipes add a lot of value - even though I don't use them. 10g is enough for a bunch of applications, and once you add the cost of the wipes it ends up cheaper than the 3.5g version (I paid <2k). While it seems a bit expensive, it seems a bit above the MX-4. As the heatload drops, the differences will get smaller. It's best for small-die GPUs, and if you have a lot of them to do. For smaller runs, Hydronaut may be a better bet and overall cost less.

The product is just awesome. I was able to reduce my gaming laptop CPU temperature by 10-15 degrees. Easy to apply and definitely works like charm!!!

Same if not batter than Kingpin kpx cooling performance for general usage. Reduced my laptop temps by 10-15°C

My 3 year old rtx2070 ran at 71c at overclock under full load. Switching to a cheap grease gave 78c without overclock at full load. Then I finally switched to this. The overclocked full load temperature dropped to 67-68 consistent, which is better than the stock in my opinion. Heat gets dissipated effectively. Just use an optimum quantity as mentioned in the instructions.

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

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.
