NT-H2 3.5g, High-Performance Thermal Paste and 3 Cleaning Wipes

TL;DR: Noctua NT-H2 delivers impressive cooling performance at a price that undercuts the competition. The included cleaning wipes are a nice touch, and it's non-conductive, giving peace of mind. It shaved off 4-6°C compared to previous thermal pastes, making it a smart choice for demanding CPUs and GPUs. Highly recommended for anyone wanting better cooling without emptying their wallet. Full Review: The Noctua NT-H2 3.5g thermal paste comes with three large cleaning wipes, which is awesome. You get plenty of paste – enough for multiple applications. Honestly, I was hoping for something effective, and its performance is surprising given the price. The paste itself looks like your typical silver compound. It's non-conductive, which is great because I don't have to worry about accidental spills frying my components, especially with some of the heat spreader designs out there. Plus, it doesn't require any “cure” time. I just applied it, mounted the cooler, and was good to go. Instant results are my kind of thing. I saw a significant temperature drop – around 4-6°C – compared to other pastes I've used. I push my hardware hard, especially my array of modded Quadro RTX GPUs. They tend to run hot even with proper airflow. The temperature drop was consistent across all the GPUs I re-pasted, which was a huge relief. It performs nearly as well as Kryonaut. Maybe Kryonaut *might* have an edge of 1°C or two under extreme load, but the cost difference makes Noctua the smarter choice for me. Basically, the Noctua NT-H2 is a fantastic performer that won't break the bank. You get more paste and the cleaning wipes, all for less than a smaller tube of Kryonaut. Unless you need liquid metal, this is easily the best deal I've found. I'm definitely sticking with this stuff. --- Product: Noctua NT-H2 3.5g, Thermal Computer Paste incl. 3 Cleaning Wipes ASIN: B07MZ45X9G

I’ve used quite a few thermal pastes over the years, and Noctua NT-H2 has quickly become one of my favorites. I recently used it during a CPU cooler upgrade, and the whole process was about as easy as it gets. The paste has a great consistency, spreads nicely under mounting pressure, and doesn’t make a mess during installation. What impressed me most was the temperature improvement. Compared to the older paste I was replacing, I saw a noticeable drop in CPU temperatures under load, which is always a welcome bonus. My system runs cooler and quieter now since the fans don’t have to work as hard. The included cleaning wipes were a nice touch as well. They made removing the old thermal compound quick and hassle-free, saving me from having to hunt down isopropyl alcohol and paper towels. It’s a small detail, but one that makes the whole installation experience more convenient. Another reason I chose NT-H2 is Noctua’s reputation for quality and long-term reliability. Once it’s applied, I don’t have to worry about it drying out or losing performance anytime soon. The 3.5g tube also goes a long way, so there’s plenty left for future builds and upgrades. Overall, this is a high-quality thermal paste that delivers exactly what it’s supposed to. If you’re building a new PC, upgrading a cooler, or simply refreshing an older system, NT-H2 is an easy recommendation. It performs well, is simple to work with, and comes from a brand that’s earned its reputation.

I ordered the 3.5 grams of NT-H2, it arrived very quickly and it even comes with wipes that easily wiped off the old MX-6 paste I previously used. This paste seems very good so far, and very easy to apply. I used it for a 9800x3d cooled with a Phantom Spirit 120 SE and temps are pretty cool never hit 70c in gaming yet.

Works like a charm! My gaming PC is running cooler than ever

I'm not much of techhie, but know well enough to change the thermal paste on my old ThinkPad every few years. I don't do temperature tests, so I have no idea how well this paste works compared to others, but it spreads easy and it works. I don't hear my laptop fan going off often, and I think it runs cooler than before. Thank you Noctua.

A product-improved version of the NT-H1. Easy to apply, easy to remove, non-conductive, and very high performance. This is up there with Grizzly Kryonaut and Gelid GC-Extreme in testing. To get anything measurably better you would need to go with conductive liquid metal thermal mediums like Conductonaut. Those are much higher risk of failure and much more difficult to work with, not worth it in anything beyond extreme overclocking applications. Can't give a temp comparison because I didn't use the stuff they sent with my Contac Silent 12 heatsink, immediately cleaned and applied the NT-H2 to it. Under a 20min stress test it never went above 70c with default fan curve, impressive for a quiet heatsink meant to keep decibels low more than keeping temps down while gaming. Packaging is very nice, you have the option of buying the larger 10g tube slightly cheaper per gram if you plan on building a few more systems or doing GPU's, the wipes are convenient (not collectibles, go ahead and use them guilt-free) and even the common complaint about price on Noctua products is not really valid. This stuff costs the same as Arctic MX-4 at the moment just under $13 for a 3.5g tube, Grizzly Kryonaut costs under $10 for a 1g tube and Gelid GC-Extreme at $14.52 for a 3.5g tube. All of these products are likely going to be within 1 degree C of the other according to multiple comparison reviews and that is within the margin of error in both measurement and user application. I added everything up and the NT-H2 came out on top as a choice for me. It's just a good deal without sacrificing any quality for your build. Highly recommended for the combination of high performance, reasonable pricing, extras in the package and ease of use. The fact it is Noctua also adds a little of that "cool factor" for anyone who tingles when they hear that brand name.

This is one of the best performing thermal pastes you can buy, without resorting to riskier "liquid metal" thermal pastes. However, it is much more expensive compared to some other pastes you can get, like GD-900. GD-900 performs almost as well as this paste, only lagging behind by a few degrees. But if you have a very hot running laptop, like my RAZER Blade Advanced 2018... this paste may be worth the extra cost. For other systems that tend to run cooler, GD-900 may work well enough, and costs much less... or is available in a much larger amount at the same price as you would pay for this syringe of Noctua. "Liquid Metal" pastes are generally the best of the best when it comes to thermal performance, but they are usually conductive and can destroy your PC if not properly applied. Conformal coatings are generally recommended for use with "Liquid Metal" pastes to help prevent shorts occurring from leakages... which it not an issue with PTM7950 or conventional pastes. PTM7950 thermal pads perform very well, but if you don't have enough mounting pressure (which can be a problem for some laptops) then it may not work well. PTM7950 is also a bit harder to find legitimate versions of (as some sellers sell knockoffs that don't work well), and it's harder to install. Once you apply it, you generally don't need to replace it. Conventional thermal pastes like this Noctua one have the benefit of being non-conductive and easy to install. The biggest con of conventional pastes is that they can dry out and stop working as well, eventually needing to be replaced. Lower quality pastes can dry out faster or have worse thermal performance.

So I bought this to repaste my 9700k with Corsair h115i platinum cooler. I felt like after a couple of years, maybe I could get the temperature to drop a few degrees lower than the paste that was pre-applied. So I ordered this noctua nt-h2 paste because it’s decently priced, but more importantly: no complaints about fakes or inconsistency!! Sure enough, I got exactly what I expected. A box with some wipes and a tube of paste that came out light grey. It’s consistency is exactly what every paste I’ve used in the last 20 years is like .. kinda thick but it squished as expected! No funniness, no inconsistency, and the temperatures were at worst the same as what they were before - with a 2 degree drop at best. That’s good enough for me! The wipes were honestly not great. They’re enormous! Like the size of a wet wipe lol. I mean, they work great if you fold them up though. Definitely not worth the money to buy separately, but pretty darn sweet to get in the package anyway. I overall really liked how they cleaned the CPU and water block - and there was way more than enough wipe to clean both thoroughly lol. So overall, I’m satisfied. It’s not blue, and it won’t drop your temperatures substantially, but it does work!

Great product. Keeps my thermals cool. :)

Good

Pâte thermique Notua parfait

llevo bastante tiempo con esta pasta térmica, es muy buenas ya que puede bajar 1 o 2 grados mas que otras pastas térmicas lo que me hizo comprarla es que viene con sus toallas de alcohol isopropílico que con una basta para limpiar el sistema de refrigeración que en este caso es una asus tuf f15, RECOMIENDO cambiar la pasta térmica segun el uso que le des ya sea esta pasta térmica o otra, solo infórmense bien sobre la conductividad térmica de la pasta

1. Noticeable Temperature Drop After applying the Noctua NT-H2, I managed to drop my CPU temps by about 10% under load. That might not sound like much on paper, but in practice it meant less thermal throttling and more stable performance during heavy gaming sessions. I could clearly see the difference compared to the stock paste I was using before. 2. Easy Application Process What impressed me most is how simple it was to apply. The paste spreads evenly without needing extra effort, and the included cleaning wipes made the prep work fast and clean. I’ve worked with pastes that are messy and hard to handle, but NT-H2 felt very forgiving. 3. Long-Term Reliability One of the reasons I chose Noctua is their reputation for stability, and this paste didn’t disappoint. It’s non-conductive, so there’s no risk of damaging components, and it’s rated to last for years without drying out. That gives me confidence I won’t need to re-apply anytime soon. 4. Perfect for CPUs and GPUs I tested it on my CPU first, but this paste is also safe for GPUs. Knowing I can use the same tube on my desktop CPU, GPU, and even a laptop repaste makes the value much better. At 3.5g, there’s enough for multiple applications. 5. Premium Brand That Delivers Noctua has always been my go-to for quality cooling, and NT-H2 reinforces that reputation. Between the lower temps, easy handling, and long-term peace of mind, I see it as an investment in system stability. It costs a bit more than generic pastes, but the performance gain justifies it.
