Overview of the Products
The CPU Air Cooler with 4X6mm Heat Pipes is priced at $23.99, making it the more budget-friendly option compared to the Thermalrlght Peerless Assassin 120 SE, which costs $32.90. While both coolers are designed for optimal CPU performance, they cater to different user needs and preferences. The upHere cooler emphasizes universal compatibility and quiet operation, while the Thermalrlght model focuses on advanced cooling technology and design.
Cooling Performance
The Thermalrlght Peerless Assassin 120 SE offers superior cooling performance with its six 6mm heat pipes and dual fan setup, which enhances airflow and heat dissipation. It employs AGHP technology, allowing for efficient heat transfer, particularly useful under heavy workloads. In contrast, the CPU Air Cooler with 4X6mm Heat Pipes features four heat pipes and a single 120mm fan. While it delivers a respectable airflow of 68.2 CFM, it may not match the cooling efficiency of the Thermalrlght, which boasts a slightly lower airflow rating of 66.17 CFM but compensates with its dual fan configuration and advanced heat exchange technology.
Build Quality and Design
In terms of build quality, the Thermalrlght Peerless Assassin 120 SE uses a combination of aluminum and copper materials, contributing to its durability and effective heat dissipation. Its offset asymmetric layout also enhances compatibility with graphics cards and motherboards. The CPU Air Cooler with 4X6mm Heat Pipes, while constructed with premium materials, does not offer the same level of advanced design features. It is designed for easy installation and unobstructed RAM access, making it a solid choice for users looking for straightforward assembly.
Noise Levels
When it comes to noise levels, both coolers are designed to operate quietly. The CPU Air Cooler with 4X6mm Heat Pipes operates at noise levels below 26 dB(A) at a fan speed of 1650 RPM. The Thermalrlght Peerless Assassin 120 SE is slightly quieter with a maximum noise level of 25.6 dB(A) at 1550 RPM. Thus, if noise reduction is a priority, the Thermalrlght has a marginal advantage, but both coolers maintain a relatively low operational sound.
Compatibility
Compatibility is a strong point for both coolers, but they differ in their socket support. The CPU Air Cooler with 4X6mm Heat Pipes supports a wide range of Intel and AMD sockets, including LGA 1700, AM5, AM4, and more. This makes it a versatile option for various builds. The Thermalrlght Peerless Assassin 120 SE also supports multiple sockets, including LGA 1700 and AM5, but requires the use of the original motherboard's backplate for installation. Users should verify compatibility with their specific setups before purchasing either cooler.
Installation Process
Both coolers boast user-friendly installation processes, but they approach it differently. The CPU Air Cooler with 4X6mm Heat Pipes features a non-disassembly fan installation, allowing users to install it without removing the motherboard or RAM. This can be a significant time-saver for those assembling their systems. The Thermalrlght Peerless Assassin 120 SE utilizes an SS2 install system that requires checking for case and motherboard compatibility but provides a robust connection to the CPU through its pressure plate design.
Price Comparison
The price difference between the two coolers is noteworthy. At $23.99, the CPU Air Cooler with 4X6mm Heat Pipes is about 17% cheaper than the Thermalrlght Peerless Assassin 120 SE, which retails at $32.90. This price point may appeal to budget-conscious consumers seeking a reliable cooling solution without breaking the bank. However, the additional cost of the Thermalrlght can be justified by its advanced features and enhanced cooling capabilities.
Which should you buy?
Ultimately, the choice between the CPU Air Cooler with 4X6mm Heat Pipes and the Thermalrlght Peerless Assassin 120 SE depends on your specific needs. If you're looking for a cost-effective, easy-to-install cooler with solid compatibility, the upHere cooler is an excellent option. However, if you prioritize superior cooling performance and advanced technology, the Thermalrlght model may be worth the extra investment. Consider your budget, performance requirements, and system compatibility when making your decision.
