Noctua's New NT-H2 Thermal Compound
by Gavin Bonshor on January 29, 2019 1:00 PM EST
Noctua has today unveiled its new NT-H2 thermal compound as well a new cleaning solution with the NA-SCW1 cleaning wipes. The NT-H2 looks to improve upon the already existing NT-H1 thermal paste with a new chemical structure and zerocuring time.
The new Noctua NT-H2 thermal compound builds upon the previous success of the NT-H1 material with a new blend of metal oxide microparticles for an improved and lower thermal resistance. The lower bond-line thickness with conventional mounting pressures allows for less air cavity concentration which should provide better thermal conductivity between the heatsink plate and the heat spreader. As with the Noctua NT-H1 compound, the new NT-H2 doesn't require a curing period and Noctua state that an application of NT-H2 can be used effectively for up to 5 years on a CPU.
The Noctua NT-H1 thermal paste was tested in a 50-paste round-up I did back in 2017
Noctua, as per their own in-house testing, determined that the NT-H2 operates up to 2°c lower than NT-H1. The NT-H2 is also non-corroding and non-conductive so there's no risk of short-circuiting components and is suitable to use with all types of heatsinks including copper, aluminium and nickel plated.
Noctua has released the NT-H2 thermal paste in two different packages; a standard 3.5 g and larger 10 g tube. Packaged with the smaller NT-H2 3.5 g paste is three new NA-CW1 cleaning wipes while the larger NT-H2 10 g will come with ten. The new Noctua NA-SCW1 cleaning wipes are designed to clean CPUs, GPUs and the contact surfaces of heatsinks. Each individual wipe is moistened with a custom detergent mixture for enhanced cleaning capability, but Noctua hasn't highlighted which materials have been used. Noctua's NA-CW cleaning wipes are available seperately in packs of 20.
On the back of the NT-H2 announcement, Noctua has revealed that it will be launching its NT-H1 thermal compound in a new 10 g package which is set to retail for 14.90 USD/EUR; the existing NT-H1 3.5 g costs 7.90 USD/EUR. There is currently no indication whether or not the new NT-H1 10 g package will include the cleaning wipes.
The new NT-H2 3.5 g will cost 12.90 USD/EUR with the 10 g package will cost 24.90 USD/EUR, while the NA-SCW1 20 pack of cleaning wipes will retail for 7.90 USD/EUR. All of these are set to hit Amazon channels within the next few days, while the stock is set to filter through to partners and retailers shortly.

If you're hoping for results that carry statistical significance it better be more like 20 tests. Replypiroroadkill - Wednesday, January 30, 2019 - link
But NT-H1 suffers from pump-out effect, hardcore. I delidded my 3770K, and applied NT-H1 between the die and IHS. The temps were amazing... for about a day. Then it just kept climbing. It was that day that I learnt about NT-H1's weakness.I replaced it with Thermal Grizzly Kryonaut, and although the temps were basically the same as when I first applied NT-H1, the temps stayed the same over the long haul.

In the video they added, it says it's 1C cooler. In my mind, not worth upgrading to NT-H2. Also all the other pastes I've seen that cool better than Kryonaut tend to be conductive, liable to short circuit electronics.. ReplyJoeyJoJo123 - Tuesday, January 29, 2019 - link
Looks OK. Reasonable product for Noctua's loyal customer base, especially if they don't want to dabble with liquid metal products.I still personally like using the liquid metal tube I got from Thermal Grizzly like 2 years ago in most places, even GPU reapplications. I never use aluminum heatsinks (ex: intel box cooler), and it performs well in copper or nickel plated copper surfaces, and a single tube lasts for quite a few applications since you use so little and spread it thin. No issues with corrosion here, just the usual light surface marring/staining which doesn't affect performance. I also protect the surrounding area with a good electrical tape, too. Liquid metal doesn't seem to harden or lose thermal properties over time, and still has its "wet" texture after dismounting the heatsink, and the better thermal transfer means better performance/lower fan rpm, depending on how you tune your settings after the fact.

The NT-H2 10g $25 package comes with 10 cleaning wipes btw Replygavbon - Tuesday, January 29, 2019 - link
We've mentioned that in the article :) - I need the wipes as it saves me using acetone and toilet paper! ReplyWatcherCK - Tuesday, January 29, 2019 - link
😂 (I hope you mean for adding and removing thermal paste) Replynpz - Tuesday, January 29, 2019 - link
Ah yes sorry, I see it now. Just ordered a tube with the wipes and I hope they're good too since paper towels leave some lint ReplySubdude - Tuesday, January 29, 2019 - link
Paper coffee filters = no lint. ReplyPeachNCream - Wednesday, January 30, 2019 - link
I just use my tongue. It leaves my CPU feeling sufficiently violated and I get a bonus snack at the same time. That's a double win. Reply
