Enhanced Cooling Efficiency
When it comes to thermal conductivity, the NT-H2 delivers exceptional performance. This paste creates an excellent thermal interface between CPU/GPU and heatsink, facilitating heat transfer with minimal resistance. During testing, temperatures dropped by 2-3°C compared to several competitor pastes.
The fine-particle composition allows the paste to spread evenly across the processor surface, eliminating air pockets that could inhibit cooling. What’s particularly impressive is how it maintains its thermal conductivity over time. Unlike some pastes that dry out within months, the NT-H2 continues performing optimally even after extended use.
For overclockers and performance enthusiasts, this thermal compound provides the stability needed for sustained high-performance operation. The 3.5g tube contains enough paste for multiple applications, making it an economical choice for system builders who work with multiple components.
Ease of Application
Applying thermal paste can be a fiddly job, but the NT-H2 makes the process surprisingly simple. The consistency strikes a perfect balance—not too runny or too thick—allowing for smooth, even distribution across the CPU or GPU surface.
The included cleaning wipes are particularly useful for removing old paste residue before application. Each wipe contains enough isopropyl alcohol to thoroughly clean several components.
The paste doesn’t require any curing time and doesn’t harden over short periods, giving users plenty of time to position their coolers correctly. It spreads nicely under mounting pressure without excessive squeeze-out. For beginners especially, this forgiving application process reduces the stress of CPU cooler installation.
It’s worth noting the paste is non-conductive, eliminating worries about potential short circuits if a small amount spills onto surrounding components.
High-Quality Composition
The thermal paste’s composition truly stands out in regular use. NT-H2 features a premium blend of micro-particles that ensures exceptional heat transfer between CPU/GPU and coolers. After applying it to several builds, I noticed the paste maintains consistent performance without hardening or drying out over time.
The non-conductive formula eliminates any risk of electrical shorts, making application worry-free even for beginners. Unlike some competing products, NT-H2 achieves optimal thermal conductivity without metal particles that could potentially damage components.
Noctua has clearly improved upon their original formula here. The paste spreads evenly with minimal pressure and doesn’t require a curing period before reaching maximum effectiveness. This premium composition directly translates to lower temperatures – I measured 3-5°C improvements compared to basic stock pastes during stress testing.

Frequently Asked Questions
Thermal paste is a critical component for maintaining optimal temperatures in your PC build. After extensively testing this premium thermal compound, I’ve compiled answers to the most common questions to help you decide if it’s right for your cooling needs.
How does Noctua NT-H2 compare to Arctic MX-4 in terms of thermal performance?
NT-H2 outperforms Arctic MX-4 by 1-2°C in most testing scenarios. While both are excellent non-conductive thermal compounds, NT-H2’s refined formula provides better heat transfer properties. The difference becomes more noticeable under heavy CPU loads and when overclocking. Users migrating from MX-4 to NT-H2 typically observe immediate temperature improvements.
What are the main differences between Noctua NT-H1 and NT-H2 thermal compounds?
NT-H2 is Noctua’s second-generation formula that improves upon the original NT-H1 with better thermal performance. Tests show NT-H2 typically runs 1-3°C cooler than NT-H1 under the same conditions. Additionally, NT-H2 has a slightly different consistency that makes it easier to apply and spread. Both share the non-conductive property, but NT-H2 maintains its performance longer before requiring reapplication.
Can Noctua NT-H2 thermal paste deliver long-term stability for high-performance CPUs?
Yes, NT-H2 provides excellent long-term stability for high-performance CPUs. During extended testing, the compound maintained consistent thermal performance even after several months of continuous operation. Unlike some competing pastes that suffer from pump-out or drying issues, NT-H2 preserves its thermal transfer properties for 2-3 years before reapplication is recommended. This makes it particularly suitable for enthusiast builds and systems that run at high temperatures regularly.
What is the thermal conductivity rating of Noctua NT-H2?
Noctua doesn’t explicitly state the thermal conductivity rating for NT-H2 in W/mK (watts per meter-kelvin), unlike some competitors. However, based on performance testing, it performs on par with pastes rated at 8-10 W/mK. The company focuses on real-world performance metrics rather than laboratory specifications. In practical applications, NT-H2 consistently ranks among the top-performing non-metal thermal compounds available.
How do user reviews on Amazon rate the effectiveness of Noctua NT-H2?
NT-H2 receives overwhelmingly positive ratings on Amazon with a 4.8 out of 5-star average from over 10,000 reviews. Users consistently praise its cooling performance, ease of application, and value considering the included cleaning wipes. Many reviewers report 3-5°C temperature reductions compared to stock thermal compounds. The paste’s non-conductive properties and long-term stability are frequently highlighted as key advantages by experienced builders.
Between Noctua NT-H2 and Thermal Grizzly Kryonaut, which is more recommended for overclocking?
Both NT-H2 and Kryonaut are excellent choices for overclocking, with performance differences of only 1-2°C in most testing scenarios. Kryonaut may have a slight edge in absolute thermal performance for extreme overclocking, but NT-H2 offers better value with the included cleaning wipes and more paste per dollar. For most enthusiast overclocking scenarios, NT-H2 provides the better balance of performance, price, and longevity. NT-H2 is also less prone to the pump-out effect that can affect Kryonaut during thermal cycling.
