Dimension comparison
Overview of the Products
The Thermalright Peerless Assassin 120 SE V2 CPU Cooler is priced at $38.99, while the Thermalright PS120SE CPU Air Cooler is slightly cheaper at $35.90. Despite the price difference of about 5% in favor of the PS120SE, both products boast impressive cooling capabilities and are designed for modern desktop systems.
The Peerless Assassin features a dual tower design with 6 heat pipes and dual 120mm PWM fans, optimizing heat dissipation, while the PS120SE provides a robust solution with 7 heat pipes and advanced AGHP 4.0 technology. This comparison will delve into the specifics of their performance, design, compatibility, and more.
Performance and Cooling Efficiency
In terms of cooling performance, the Thermalright Peerless Assassin is equipped with dual 120mm fans capable of reaching speeds of 1850 RPM, generating a maximum airflow of 88.89 CFM. This design allows for efficient heat transfer, making it suitable for gaming and multitasking.
Conversely, the PS120SE utilizes a slightly lower fan speed of 1500 RPM but still delivers a respectable airflow of 66.17 CFM. While its cooling capability is commendable, the Peerless Assassin’s higher RPM and airflow may provide superior cooling efficiency under heavy loads. Thus, for intense gaming sessions or multitasking, the Peerless Assassin might have the edge in performance.
Design and Build Quality
The Thermalright Peerless Assassin has a dual tower structure, which not only enhances its cooling performance but also adds to its aesthetic appeal. Its dimensions are 125mm x 110mm x 155mm without the fan, and it is constructed with a pure copper base and aluminum fins, ensuring durability and effective heat dissipation.
On the other hand, the PS120SE stands slightly taller at 125mm x 135mm x 154mm, featuring a blend of anodized black frosted aluminum and finely carved pure copper base technology. While both coolers boast quality materials and effective designs, the Peerless Assassin’s dual tower design may provide an advantage in maximizing cooling potential.
Compatibility and Installation
The Peerless Assassin supports both AMD AM4/AM5 and Intel LGA1851/1700 platforms, making it a versatile choice for a variety of builds. Its broad socket compatibility facilitates installation across many modern desktop setups.
In comparison, the PS120SE also supports a wide range of Intel and AMD sockets, including LGA1700, 1150, 1151, 1155, 1156, and 1200, alongside AM4/AM5. This extensive compatibility makes both coolers suitable for most contemporary CPUs. However, users should verify that their specific motherboard configuration aligns with the cooler's mounting requirements for a hassle-free installation.
Noise Levels and Operation
When it comes to noise levels, the Peerless Assassin operates at a maximum of 29.5 dBA, which is relatively quiet for a cooling solution of its caliber. This ensures that gamers and professionals can work without significant distractions.
In contrast, the PS120SE has a lower noise level of up to 25.6 dBA, making it an excellent option for users who prioritize a silent operating environment. While both coolers are designed to operate quietly, the PS120SE has a slight advantage in minimizing sound output, appealing to those sensitive to noise during operation.
Longevity and Reliability
The Thermalright PS120SE features S-FDB bearings, which contribute to its longevity, with a service life of up to 20,000 hours. This durability ensures that users can rely on the cooler for extended periods without concern for premature failure.
While the Peerless Assassin does not specify a service life, its construction from quality materials like pure copper and aluminum suggests a solid build. However, the PS120SE’s explicit longevity claim may provide added peace of mind for users considering long-term use.
Price Comparison
The Thermalright Peerless Assassin is priced at $38.99, while the PS120SE is available for $35.90, making the PS120SE about 5% cheaper. This price difference might be relevant for budget-conscious consumers looking for effective cooling solutions without breaking the bank.
Both coolers offer excellent value for the performance they deliver. While the Peerless Assassin justifies its higher price with superior cooling performance, the PS120SE remains an attractive option at a lower price point, particularly for users who prioritize quiet operation and longevity.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 SE V2 CPU Cooler and the Thermalright PS120SE CPU Air Cooler largely depends on your specific needs. If you require superior cooling performance for intensive tasks and are willing to invest a bit more, the Peerless Assassin is a strong candidate with its dual tower design and higher airflow capabilities.
However, if you prioritize a quieter operation and a slightly lower price, the PS120SE may be the better choice, especially given its longevity and compatibility with a wide range of CPU sockets. Ultimately, both products deliver solid performance and reliability, making either a worthwhile addition to your PC cooling arsenal.
