Dimension comparison
Price Comparison
The Cooler Master Hyper 212 Spectrum V3 is priced at $18.99, while the Thermalrlght Peerless Assassin 120 SE comes in at $32.90. This makes the Cooler Master about 43% cheaper than its competitor. If budget is a primary concern, the Cooler Master is the clear winner, providing a solid cooling solution without breaking the bank. The significant price difference could allow users to allocate funds for other components, enhancing their overall build without compromising on cooling performance.
Cooling Performance
When it comes to cooling performance, the Thermalrlght Peerless Assassin 120 SE boasts six heat pipes compared to the Cooler Master’s four. The additional heat pipes in the Peerless Assassin facilitate improved heat dissipation, which can be crucial for high-performance CPUs. The Cooler Master, while having fewer heat pipes, still delivers optimal cooling for AMD R7 and Intel i7 processors, thanks to its silver nickel-plated copper base and a robust 120mm PWM fan. For users with high thermal demands, the Peerless Assassin may offer a more efficient cooling solution.
Fan Technology
The Cooler Master utilizes a single 120mm high-performance PWM fan that can operate between 650 to 1,750 RPM, allowing for adjustable airflow and noise levels. In contrast, the Thermalrlght comes equipped with two 120mm TL-C12C PWM fans that can reach a speed of 1,550 RPM. This dual-fan setup provides greater airflow, rated at 66.17 CFM, which may be advantageous for users engaged in overclocking or intensive tasks. However, the quieter operation of the Cooler Master at lower RPMs could appeal to those prioritizing low noise levels.
Compatibility
The Cooler Master Hyper 212 Spectrum V3 supports a wide range of Intel and AMD sockets, including AMD AM5/AM4 and Intel LGA 1851/1700/1200. The redesigned brackets simplify installation on these platforms, making it user-friendly. The Thermalrlght Peerless Assassin 120 SE also supports multiple sockets, including AMD AM4/AM5 and Intel LGA 1700/1150/1151/1200/1851, but requires the use of the original motherboard's backplate for installation, which may complicate setup for some users. Both coolers offer good compatibility, but the Cooler Master may have the edge in ease of installation.
Design and Aesthetics
In terms of design, the Cooler Master features a frosted blade design for its fan, which enhances the dispersion of its aRGB lighting. This allows for customizable lighting effects, appealing to gamers and PC builders who value aesthetics. On the other hand, the Thermalrlght has a brushed black top cover and a more industrial look with its aluminum heatsink. While both coolers have their unique styles, the Cooler Master's focus on customizable RGB lighting makes it more attractive for those looking to match their build’s theme.
Installation Ease
The Cooler Master is designed with simplified brackets for easy installation, particularly on modern AMD and Intel platforms. This user-friendly approach makes it an appealing choice for novice builders or anyone seeking a hassle-free setup. In contrast, the installation of the Thermalrlght Peerless Assassin may require additional steps, especially since users must utilize their motherboard’s backplate. While both coolers are relatively straightforward to install, the Cooler Master provides a smoother experience for first-time builders.
Noise Levels
The Cooler Master operates at a noise level that can be adjusted from 650 to 1,750 RPM, allowing users to find a balance between performance and noise. This can be particularly beneficial in quiet environments or for users who prioritize low noise. The Thermalrlght's fans are rated at a maximum noise level of 25.6 dB(A), which is relatively quiet for a dual-fan setup. However, with the added fan, it may produce slightly more noise under load compared to the Cooler Master. Depending on individual preferences, either cooler could be suitable, but the Cooler Master likely has an advantage in noise control during lighter use.
Which should you buy?
Choosing between the Cooler Master Hyper 212 Spectrum V3 and the Thermalrlght Peerless Assassin 120 SE ultimately depends on your specific needs and preferences. The Cooler Master is significantly more affordable at $18.99, providing excellent cooling for most users, especially those on a budget. Its user-friendly installation, quieter operation, and customizable RGB lighting make it an attractive option for a wide range of builds. Conversely, if you require superior cooling performance and plan to push your CPU to its limits, the Thermalrlght Peerless Assassin, with its dual fans and six heat pipes, might be worth the extra investment at $32.90. Consider your cooling requirements, budget, and aesthetic preferences when making your decision.
