Thermalright Peerless Assassin 120 SE CPU Air Cooler vs Noctua NT-H2 3.5g AM5 Edition

Brand Overview

Thermalright and Noctua are both well-regarded brands in the cooling solutions market, with distinct focuses and strengths. Thermalright has over 20 years of experience, concentrating on computer accessories, including CPU air coolers and thermal compounds. Noctua, on the other hand, is known for its premium-grade thermal solutions, with a reputation for high quality and performance.

Thermalright’s Peerless Assassin 120 SE is designed for high-performance cooling with features like double tower cooling and advanced heat pipe technology. Noctua’s NT-H2 3.5g AM5 Edition, while not a cooler itself, is a premium thermal compound that enhances heat transfer between CPUs and heatsinks, making it a crucial accessory for optimal cooling efficiency.

Cooling Performance

When it comes to cooling performance, the Thermalright Peerless Assassin 120 SE stands out with its ability to handle a thermal design power (TDP) of 120 to 265W. This impressive range allows it to effectively cool high-performance CPUs, making it suitable for gamers and content creators alike. The cooler is equipped with two PWM fans that can spin up to 1550 RPM, generating an airflow of 66.17 CFM while maintaining a noise level of just 25.6 dB(A).

In contrast, the Noctua NT-H2 is a thermal paste designed to optimise the heat transfer from the CPU to the heatsink but does not provide cooling itself. Its effectiveness is evident in its ability to ensure that CPUs maintain optimal temperatures when paired with a quality cooler. The NT-H2 is the second generation of Noctua’s NT-H1, known for its excellent long-term stability, which can be crucial for sustaining cooling performance over time.

Installation and Compatibility

The Thermalright Peerless Assassin 120 SE offers a variety of mounting options to ensure compatibility with different CPU platforms. It supports both Intel (115X/1200/1700) and AMD (AM4) sockets, making it versatile for a range of builds. The cooler comes equipped with the necessary mounting hardware and is designed for straightforward installation, allowing users to easily set it up without additional tools.

On the other hand, the Noctua NT-H2 thermal compound is easy to apply and does not require spreading before heatsink installation. This user-friendly approach, combined with the included NA-CW1 cleaning wipes, simplifies the process of maintaining a clean application, which is especially beneficial for users who frequently change components. The NT-H2 is suitable for various CPU sizes, providing around 3 to 20 applications depending on the specific CPU model, making it a flexible choice for different setups.

Noise Levels

Noise levels are a critical consideration for many users, particularly those building silent or low-noise systems. The Thermalright Peerless Assassin 120 SE operates at a maximum noise level of 25.6 dB(A), which is relatively quiet for a cooler with such robust cooling capabilities. This makes it an excellent choice for users who prioritise a peaceful computing environment without sacrificing performance.

In comparison, the Noctua NT-H2 does not generate noise itself, as it is a thermal compound. However, the effectiveness of the thermal paste can indirectly influence the overall noise levels of a system by allowing the CPU cooler to operate more efficiently and potentially at lower RPMs, further contributing to a quieter build.

Price Point

The Thermalright Peerless Assassin 120 SE is priced at £29.99, reflecting its advanced features and cooling capabilities. This price point is competitive for a high-performance air cooler, especially considering its dual fan setup and extensive compatibility with various CPU sockets.

In contrast, the Noctua NT-H2 is significantly more affordable at £12.11. This price makes it an accessible option for users who want to enhance their CPU cooling without a substantial investment. Given that it can provide multiple applications, the NT-H2 offers excellent value for money, particularly for those looking to maintain optimal thermal performance across different builds.

Longevity and Reliability

Longevity and reliability are paramount when selecting cooling solutions. The Thermalright Peerless Assassin 120 SE is built with quality materials, including a copper base and aluminum heat sink, designed to withstand extensive use while maintaining performance. Its heat pipes utilise AGHP technology, which helps mitigate the inverse gravity effect, ensuring efficient heat transfer regardless of orientation.

Noctua’s NT-H2 thermal compound boasts a recommended storage time of up to three years and a usage time of up to five years once applied. This longevity makes it a reliable choice for users who want a thermal interface material that won’t degrade quickly, ensuring sustained cooling performance over time.

Which should you buy?

Choosing between the Thermalright Peerless Assassin 120 SE and the Noctua NT-H2 largely depends on your specific cooling needs. If you require a high-performance air cooler capable of supporting demanding CPUs, the Thermalright Peerless Assassin 120 SE is the clear choice with its robust cooling capabilities and excellent compatibility. However, if you’re looking for a reliable thermal compound to enhance the performance of your existing cooler, the Noctua NT-H2 offers outstanding value, ease of application, and long-term stability. Consider your setup and priorities to make the best choice for your cooling requirements.
