Price Comparison
When it comes to pricing, the AMD Wraith Stealth is significantly more affordable than the Thermalright Peerless Assassin 120 SE V3. The AMD cooler is priced at $11.12, while the Thermalright model costs $35.90, making it about 223% more expensive. For budget-conscious buyers, this price difference is substantial, especially when considering that both products aim to perform similar functions in cooling CPUs.
The AMD Wraith Stealth is a great choice for those who are looking for a cost-effective solution without sacrificing too much on performance. On the other hand, if you have a larger budget, the Thermalright cooler offers advanced features that may justify the higher price tag.
Cooling Performance
The Thermalright Peerless Assassin 120 SE V3 is designed for superior cooling performance, boasting a double-tower dual-fan structure and six heat pipes. This design is geared towards efficiently dissipating heat, making it ideal for high-performance CPUs. The dual PWM fans can reach speeds of up to 2000 RPM, creating a substantial airflow of 70.84 CFM, which is crucial for heat dissipation.
In comparison, the AMD Wraith Stealth features a single 3.93-inch fan and is suitable for moderate cooling needs. While it does come with an aluminum heatsink and pre-applied thermal paste, its cooling capabilities are limited compared to the more robust design of the Thermalright model. Therefore, for users with high-performance CPUs or overclocking in mind, the Thermalright cooler is likely the better choice.
Build Quality and Design
The Thermalright Peerless Assassin 120 SE V3 is constructed with a blackened anodic matte top sheet and features a nickel-plated copper base. This attention to material quality not only enhances its aesthetic appeal but also contributes to durability and heat dissipation efficiency. Its symmetrical all-aluminum fins and dual fans further reinforce its robust design.
Conversely, the AMD Wraith Stealth is made primarily from aluminum and includes a copper core base. While it is a genuine AMD product and has a solid build for entry-level cooling, it lacks the advanced materials and design features that the Thermalright offers. Those looking for a cooler that combines functionality with a premium feel may lean towards the Thermalright model.
Installation Process
Both coolers are designed for ease of installation, but there are notable differences. The AMD Wraith Stealth connects directly to the AM4 motherboard with its direct screw mounting system, simplifying the installation process for users who may not have extensive experience with CPU coolers.
On the other hand, the Thermalright Peerless Assassin 120 SE V3 requires the use of the original backplate of the motherboard during installation. While it comes with mounting accessories, some users might find this slightly more complex compared to the straightforward installation of the AMD cooler. For those who prioritize simplicity and ease, the AMD Wraith Stealth may be the more appealing option.
Compatibility
The Thermalright Peerless Assassin 120 SE V3 offers a wider range of compatibility, supporting both AMD and Intel platforms, including AM4, AM5, and several Intel LGA sockets. This versatility makes it a more future-proof option for users who may upgrade their systems in the future.
In contrast, the AMD Wraith Stealth is specifically designed for the AM4 socket. While it performs well within its designated compatibility, users who might switch to Intel platforms or newer AMD sockets will find the Thermalright cooler to be a more adaptable choice. Thus, if future compatibility is a priority, the Thermalright model stands out.
Noise Levels
When it comes to noise levels, the Thermalright Peerless Assassin 120 SE V3 operates at a maximum noise level of ≤29.8 dB(A), which is relatively quiet given its performance capabilities. This is a crucial factor for users who are sensitive to noise or who prefer a quieter computing environment.
The AMD Wraith Stealth, while not explicitly stated, is generally known for its quieter operation due to its smaller fan size and lower RPM. However, without specific dB ratings, it’s hard to make a direct comparison. Overall, if noise levels are a significant concern, the Thermalright cooler provides a good balance between performance and acoustic output.
Aesthetics
Aesthetic appeal can play a role in the decision-making process for many PC builders. The Thermalright Peerless Assassin 120 SE V3 features a sleek, modern design with a matte finish and an intricate heat pipe layout, making it a visually striking addition to any build.
In contrast, the AMD Wraith Stealth has a more utilitarian look, which is functional but may not match the visual flair of the Thermalright model. For users looking to create a visually captivating build, the Thermalright cooler is likely to be the preferred option due to its aesthetic design.
Which should you buy?
Deciding between the AMD Wraith Stealth and the Thermalright Peerless Assassin 120 SE V3 ultimately depends on your specific needs and budget. If you are seeking an affordable, straightforward cooling solution for a basic AM4 setup, the AMD Wraith Stealth is an excellent choice at just $11.12. However, if you require more advanced cooling capabilities, wider compatibility, and superior aesthetics, the Thermalright cooler, priced at $35.90, may be worth the investment. Consider your cooling needs, budget constraints, and future upgrade plans to make the best decision for your setup.
