Overview of AMD Wraith Stealth and Thermalright Assassin X120

The AMD Wraith Stealth is priced at $11.12, making it a budget-friendly option compared to the Thermalright Assassin X120, which costs $17.90. This price difference of about 61% makes the Wraith Stealth an attractive choice for users looking for a cost-effective cooling solution. While both coolers are designed for effective heat dissipation, their features and performance capabilities differ significantly, catering to different user needs.

Cooling Performance

When it comes to cooling performance, the Thermalright Assassin X120 stands out with its advanced design that includes four heat pipes and a TL-C12C PWM fan capable of producing an airflow of 66.17 CFM. In contrast, the AMD Wraith Stealth features a 3.5-inch fan that, while adequate for standard cooling tasks, may not match the thermal efficiency of the Assassin X120 under heavy loads. For users with high-performance CPUs, the superior airflow and heat pipe technology of the Assassin X120 could provide a noticeable advantage.

Design and Build Quality

The build quality of the Thermalright Assassin X120 is enhanced by its aluminum heatsink cover and the use of AGHP technology, which optimizes thermal transfer. It also boasts a robust design suitable for various CPU sockets, including AMD AM4 and AM5, as well as Intel’s LGA series. Meanwhile, the AMD Wraith Stealth features an aluminum heatsink with a copper core, complemented by pre-applied thermal paste for ease of installation. While both coolers are made from quality materials, the Assassin X120's advanced construction offers more durability and efficiency.

Compatibility

In terms of compatibility, the AMD Wraith Stealth is specifically designed for the AM4 socket, making it ideal for users of AMD Ryzen processors. On the other hand, the Thermalright Assassin X120 shows broader compatibility with both AMD and Intel sockets, including AM4, AM5, and several Intel LGA variants. This versatility makes the Assassin X120 a more flexible choice for users who might switch between different CPU platforms in the future.

Noise Levels

The Thermalright Assassin X120 operates at a noise level of 25.6 dB(A) while delivering strong cooling performance, ensuring a quiet computing environment. The AMD Wraith Stealth's noise levels are not specified, but it is generally considered a quieter option suitable for average workloads. Users who prioritize a silent operation during intensive tasks may find the Assassin X120's performance more appealing due to its balance of cooling efficiency and low noise.

Installation Process

Both coolers are designed for straightforward installation, but the AMD Wraith Stealth shines in its simplicity, featuring direct screw mounting to the AM4 motherboard. This ease of installation is beneficial for users who may not be very experienced with PC building. Conversely, while the Thermalright Assassin X120 includes metal fasteners for both Intel and AMD platforms, the installation process may be slightly more complex due to its additional compatibility options.

Price Comparison

The AMD Wraith Stealth is priced at $11.12, which makes it about 61% cheaper than the Thermalright Assassin X120, priced at $17.90. This significant price gap could be a deciding factor for budget-conscious consumers or those who do not require advanced cooling features. While the Assassin X120 offers superior performance, the Wraith Stealth is a solid option for users with lighter workloads who still want reliable cooling without breaking the bank.

Which should you buy?

Choosing between the AMD Wraith Stealth and the Thermalright Assassin X120 ultimately depends on your specific needs and budget. If you are looking for an affordable, reliable cooler for an AMD AM4 processor, the Wraith Stealth is an excellent option at just $11.12. However, if you require superior cooling performance, broader compatibility, and quieter operation, the Thermalright Assassin X120, priced at $17.90, is well worth the investment.
