Overview
In the realm of CPU coolers, the Thermalright Assassin X120 Refined SE and the Thermalright Phantom Spirit 120 Digital EVO stand out as solid choices. However, they cater to different needs and preferences in cooling performance and design. The Assassin X120 Refined SE is priced at $17.90, while the Phantom Spirit 120 Digital EVO is more premium at $56.90, making it about 217% more expensive. Understanding the nuances between these two products can help you make an informed decision for your cooling requirements.
Design and Build Quality
The design of a CPU cooler significantly impacts not only aesthetics but also cooling efficiency. The Thermalright Assassin X120 Refined SE features an aluminum heatsink cover and measures 125(L)x71(W)x148(H)mm, ensuring it fits comfortably in medium-sized cases. In contrast, the Phantom Spirit 120 Digital EVO has a dual-tower design that stands taller at 160mm, adding to its cooling capacity. Its sleek, dark finish combined with an ARGB magnetic display panel enhances its visual appeal, making it a standout in any build.
Cooling Performance
When it comes to cooling performance, the Thermalright Phantom Spirit 120 Digital EVO excels with its seven heat pipes and dual 120mm PWM fans capable of reaching speeds of 2150 RPM and an airflow of 69 CFM. In comparison, the Assassin X120, with its four heat pipes, achieves a fan speed of 1550 RPM and airflow of 66.17 CFM. While both coolers are effective, the Phantom Spirit offers superior cooling potential, making it a better choice for high-performance CPUs or overclocking setups.
Noise Levels
Noise levels are a crucial consideration for many users. The Thermalright Assassin X120 Refined SE operates at a maximum noise level of 25.6 dB(A), which is relatively quiet and suitable for a peaceful workspace. The Phantom Spirit 120 Digital EVO, on the other hand, has a slightly higher noise level of 27 dB(A). While both coolers are designed to provide efficient cooling with minimal noise, the Assassin X120 holds a slight advantage in maintaining a quieter operation.
Compatibility
Compatibility is essential when selecting a CPU cooler. Both the Thermalright Assassin X120 and the Phantom Spirit 120 are compatible with a variety of AMD and Intel socket types, including AM4, AM5, and LGA 1700/1150/1151/1200. The Assassin supports a wider range of Intel sockets (including 1150, 1151, 1155, and 1156) while the Phantom Spirit focuses on modern platforms. This makes the Assassin X120 a more versatile option for users with older systems, whereas the Phantom Spirit targets newer builds.
Fan Technology
Fan technology plays a significant role in the effectiveness of CPU coolers. The Thermalright Assassin X120 is equipped with a TL-C12C PWM fan, which efficiently balances airflow and noise. The Phantom Spirit 120 boasts dual PWM fans that not only enhance cooling performance but also come with an RGB feature for added flair. Both coolers utilize PWM technology for intelligent speed adjustments based on temperature, but the dual-fan setup in the Phantom Spirit provides better airflow, making it ideal for high-demand applications.
Price Point
The price difference between these two CPU coolers is quite substantial. The Thermalright Assassin X120 Refined SE is priced at $17.90, while the Phantom Spirit 120 Digital EVO costs $56.90, making the latter around 217% more expensive. This significant price gap reflects the additional features and enhanced cooling performance of the Phantom Spirit. For budget-conscious consumers or those with basic cooling needs, the Assassin X120 offers excellent value without compromising quality.
User Experience and Installation
User experience can vary significantly between products. The Thermalright Assassin X120 is designed for easy installation, coming with metal fasteners compatible with both Intel and AMD platforms. The Phantom Spirit 120 also promises straightforward installation with dual platform installation clips, although it requires the original motherboard backplane for AMD setups. Both coolers aim to simplify the installation process, making them accessible even for novice builders.
Which should you buy?
Choosing between the Thermalright Assassin X120 Refined SE and the Thermalright Phantom Spirit 120 Digital EVO ultimately depends on your specific needs. If you are looking for a budget-friendly option that provides reliable cooling for standard builds, the Assassin X120 at $17.90 is a wise choice.
