    • Amazing stuff
A huge upgrade from my beloved Arctic Silver 5. As an old timer PC builder who started with Arctic Silver 3 and moved up to 5 going to this compound caught me off guard. I shaved about 10C off my 5800x3D load temps under AIO water cooling and the application was dead simple. Be sure to watch the video, the installation was different from what I was used to. I also used this on 2xE5-2680 v4 Xeon CPUs and the air cooled temps are ridiculously low. Will recommend to others going forward. Replaced my “go to” compound and is so easy to use. Love The longevity rating as well. Overall, zero complaints!!! ... show more

    • Noctua H2 keeps my Xeon 3175X nice and cool!

First of all, I have used all of the thermal pastes available today, and I needed something they came with a lot of paste and was affordable. I also have a very extreme cooling system. I run a test bench style PC daily, (5) D5 pumps at 100%, Hailea 1/2HP Water-Chiller, and a 10 gallon buffer tank. This system keeps my Xeon w3175X CPU at about 67c package max at 4.5Ghz on all 28/56 cores during R23 runs. This Noctua H2 paste works fantastic! Xeon w-3175X@4.5 (Very easily achieved overclock) Asus Dominus Extreme LGA 3647 motherboard (12x16GB) G.Skill Ares Samsung B-Die@3800cl14 RTX4090 Gaming OC This system runs nice and cool with the help of H2 paste. My CPU is really large in size, so I had to use a ton of paste. I will be buying more H2 paste! ... show more

    • Very high quality in every aspect
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. ... show more

    • The Best Value Thermal Paste
This is probably one of the best deals in terms of thermal pastes that you can buy right now. Not only do you get 3.5g of thermal paste for the cost (which is at least 5-8 applications worth of paste on average), but it also comes with 3 high quality, large cleaning wipes. Additionally, for the value you are getting, this thermal paste is also nearly as performant as some of the top thermal paste brands such as Thermal Grizzly's Kryonaut. The paste itself is nothing special appearance wise as it's your standard silvery thermal paste you all know and love, but it is also fortunately non-conductive as well as having no necessary cure time. This is great as it means it won't short out your CPU if it spills over the sides (which is a common occurrence on the new AM5 Ryzen heat spreader design) and it means the paste will be at full effectiveness right out of the gate without any waiting or paste burn-in time. All you have to do is apply the paste, mount the cooler, and that's it. No worries about shorts or high temps with this paste (as long as you still have an adequate heatsink that is). Regardless, I was getting some impressive 5-8°C temperature reductions compared to the MX-4 paste I had been using previously. This is especially important as I am using a Ryzen 7700X with this paste, which in itself already gets really hot regardless of the cooler used. I won't go into detail about the coolers as this review is about the paste itself, and the temperature reductions were similar on each cooler I tried when compared to the MX-4. The more interesting part of this review, however, is when I compared it to Kryonaut. This paste and Kryonaut are incredibly close in temp performance, usually with Kryonaut about 1-2°C cooler in some cases, but that's close enough for me to say that this NT-H2 paste has near equal performance to the much more costly Kryonaut paste. Overall, this is an incredibly high performing paste and an excellent value. For just a little more in cost compared to the base 1g kit of Kryonaut, you not only get nearly the same level of performance, but you also get 3.5x more thermal paste and 3 high quality cleaning wipes. In the end, I would highly recommend getting this thermal paste as I personally believe it to be the best "all-around" deal that is currently available. It meets all the standards that I have, and it's difficult for me to choose any other paste over this one unless you want to move up to liquid metal options. ... show more

    • Overall best value
I have used many other TIM's over the past year, including some with higher thermal rating. None have produced better temp results than H2. It is easy to apply (I use the 3-line method) and low cost per gram. As usual, Noctua products deliver performance and quality. This is my standard CPU paste now. ... show more

    • Very good !
In my opinion it’s one of the best thermal pastes, it is quite thick but it keeps my cpu running cool. I also like that it doesn’t cost a lot.
