Overview of the Thermalright Assassin X120 SE ARGB CPU Air Cooler
The Thermalright Assassin X120 SE ARGB CPU Air Cooler is a robust option for gamers and PC enthusiasts, combining effective cooling with aesthetic appeal. Priced at £16.29, it features a unique ARGB lighting system that enhances the visual aspect of your build. The cooler measures 120mm in length, 71mm in width, and 148mm in height, making it suitable for medium-sized computer cases.
This cooler uses advanced AGHP technology with four 6mm heat pipes to address gravity's effects during operation. With a maximum fan speed of 1550 RPM and an airflow capacity of 66.17 CFM, it provides efficient cooling while maintaining a noise level of only 25.6 dB(A). Its compatibility with various Intel and AMD sockets further enhances its versatility for different builds.
Overview of the ARCTIC P8 PWM PST - PC Fan
The ARCTIC P8 PWM PST - PC Fan is a cost-effective cooling solution priced at £6.26. Its design focuses on optimal performance, making it suitable for heatsinks and radiators due to its high static pressure capabilities. With a fan speed range of 200 to 3000 RPM, it offers extensive regulation options through PWM technology, allowing for synchronous control with other fans.
The fan delivers an airflow of 23.4 CFM while maintaining a low noise level of just 0.3 Sone, making it an excellent choice for users prioritising quiet operation. Additionally, the P8 PWM PST fan's latest generation PWM IC ensures energy efficiency without sacrificing performance, making it a smart choice for budget-conscious consumers.
Cooling Performance Comparison
In terms of cooling performance, the Thermalright Assassin X120 SE ARGB outshines the ARCTIC P8 PWM PST. With a fan speed of 1550 RPM and airflow of 66.17 CFM, the Assassin X120 SE is designed to handle significantly higher thermal loads than the P8, which operates at a maximum speed of 3000 RPM but only achieves 23.4 CFM of airflow.
This indicates that while the P8 can spin faster, the overall cooling efficiency of the Assassin X120 SE is superior due to its larger airflow capacity. Users looking to cool powerful CPUs or those engaged in heavy gaming will find the Assassin X120 SE a more reliable choice for maintaining lower temperatures.
Noise Levels and Operation
When it comes to noise levels, the ARCTIC P8 PWM PST is significantly quieter than the Thermalright Assassin X120 SE. The P8 operates with a maximum noise level of just 0.3 Sone, making it barely noticeable during use. In contrast, the Assassin X120 SE has a noise level of up to 25.6 dB(A), which, while not excessively loud, is noticeably more intrusive, especially in quiet environments.
For users who value a silent operation, such as those in office settings or living rooms, the P8's quieter performance makes it a more attractive option. However, the slightly higher noise level of the Assassin X120 SE may be acceptable for those prioritising performance over silence.
Aesthetic Appeal
Aesthetic considerations can play a significant role in the choice between these products. The Thermalright Assassin X120 SE ARGB CPU Air Cooler features dynamic ARGB lighting, providing colourful illumination that can enhance the visual appeal of your computer build. This feature makes it appealing for gamers who want their setup to stand out.
On the other hand, the ARCTIC P8 PWM PST does not focus on aesthetics, instead prioritising efficiency and functionality. It is available in a standard design that may not offer the same visual flair as the Assassin X120 SE. Therefore, if aesthetics are vital to your build, the Assassin X120 SE is the clear winner.
Installation and Compatibility
The installation process and compatibility of the Thermalright Assassin X120 SE is straightforward, with metal fasteners provided for both Intel and AMD platforms. It supports a wide range of CPU sockets, including Intel’s LGA1150 to LGA1700 and AMD’s AM4 and AM5. This broad compatibility makes it a versatile choice for various systems.
Conversely, the ARCTIC P8 PWM PST is a standard PC fan designed for easy installation in any 120mm fan slot. However, it lacks the dedicated compatibility features of a CPU cooler. Users looking for a comprehensive cooling solution for their CPU will find the Assassin X120 SE more suited to their needs, while the P8 is ideal as a supplementary fan for general airflow.
Price and Value
In terms of price, the Thermalright Assassin X120 SE is significantly more expensive at £16.29 compared to the ARCTIC P8 PWM PST, which retails for just £6.26. The higher price of the Assassin X120 SE reflects its dual functionality as both a CPU cooler and an aesthetic enhancement for builds.
While the P8 offers exceptional value as a budget-friendly fan that performs well for basic cooling needs, it lacks the advanced features and cooling performance of the Assassin X120 SE. Therefore, for users seeking high-performance cooling, the investment in the Assassin X120 SE may justify its higher price.
Which should you buy?
Choosing between the Thermalright Assassin X120 SE ARGB CPU Air Cooler and the ARCTIC P8 PWM PST depends largely on your specific needs. If you are a gamer or a PC enthusiast looking for robust cooling performance and aesthetic enhancements, the Assassin X120 SE is the ideal choice, offering superior airflow and compatibility with a range of CPUs. However, if you are on a budget and require a quiet, energy-efficient fan for general use, the ARCTIC P8 PWM PST is a commendable option. Ultimately, your choice should be guided by your cooling requirements, aesthetic preferences, and budget considerations.
