Dimension comparison
Overview of the Products
The ARCTIC P12 and the Thermalright Assassin X120 SE ARGB CPU Air Cooler are two noteworthy contenders in the cooling market, each boasting unique features and specifications. The ARCTIC P12 is priced at £21.58, while the Thermalright Assassin X120 SE is more affordable at £16.29. Both products cater to users seeking effective cooling solutions for their PC builds, but they do so in different ways, appealing to various preferences and needs.
Design and Build Quality
Both the ARCTIC P12 and the Thermalright Assassin X120 SE are designed with user experience and performance in mind, but they have distinct approaches. The ARCTIC P12 features an innovative design aimed at optimising airflow and minimising noise levels. The unique blade design allows for efficient ventilation, making it suitable for heatsinks and radiators. The Thermalright Assassin X120 SE, on the other hand, includes a combination of an aluminium heat sink and PWM fans that produce a colourful ARGB light effect. This cooler is built with metal fasteners for Intel and AMD platforms, emphasising versatility and user-friendliness.
Cooling Performance
In terms of cooling performance, the ARCTIC P12 excels with a fan speed of 1800 RPM, delivering an airflow of 56.3 CFM and a static pressure of 2.2 mmH₂O. This makes it particularly effective for setups that require high static pressure, such as those with heatsinks. Conversely, the Thermalright Assassin X120 SE offers a slightly higher airflow of 66.17 CFM at a fan speed of 1550 RPM but operates at a noise level of up to 25.6 dB(A). This indicates that while the Assassin X120 SE may provide more airflow, it does so with a potentially greater noise output compared to the quieter ARCTIC P12.
Noise Levels
Noise levels are a critical consideration for many PC builders, and here the ARCTIC P12 has a notable advantage. With a noise level rated at just 0.3 Sone, it is designed for quiet operation, making it ideal for users who want a peaceful computing environment. On the other hand, the Thermalright Assassin X120 SE has a noise level that can reach 25.6 dB(A), which, while still relatively low, may be more noticeable in quiet settings. Thus, users prioritising silence may prefer the ARCTIC P12 over the Thermalright model.
Longevity and Durability
Durability is another essential factor when choosing a CPU cooler. The ARCTIC P12 utilises a Fluid Dynamic Bearing that is designed to have a long service life while maintaining quiet operation. This design is enhanced by an oil capsule that prevents lubricant leakage, thereby prolonging the bearing's lifespan. In comparison, the Thermalright Assassin X120 SE also boasts a long service life, rated at up to 20,000 hours, and employs S-FDB bearings. Both coolers are built for longevity, but the ARCTIC P12's design may offer a quieter and potentially longer-lasting option.
Installation and Compatibility
When it comes to installation, the Thermalright Assassin X120 SE appears to have the upper hand due to its compatibility with a wide range of CPU sockets, including Intel's LGA 1700 and 1851, as well as AMD's AM4 and AM5. The inclusion of metal fasteners aids in achieving a better installation. The ARCTIC P12, while highly efficient, is a fan rather than a full cooler and is typically installed in conjunction with heatsinks or radiators. Therefore, users looking for a complete CPU cooling solution may find the Thermalright Assassin X120 SE more accommodating.
Aesthetic Appeal
Aesthetics can play a significant role in a PC build, and here the Thermalright Assassin X120 SE shines with its ARGB lighting effects, allowing users to customise their cooling solution's look to match their build's theme. In contrast, the ARCTIC P12 focuses more on performance and noise reduction without any RGB features. For those who value visual flair in their system, the Assassin X120 SE may be the more appealing choice, while the P12 is tailored for a more utilitarian approach.
Which should you buy?
Ultimately, the choice between the ARCTIC P12 and the Thermalright Assassin X120 SE ARGB CPU Air Cooler comes down to individual priorities. If you seek a quiet operation, efficient airflow, and longevity, the ARCTIC P12 is an excellent choice at £21.58. However, if you prefer a cooler with aesthetic appeal, higher airflow, and broader compatibility at a lower price of £16.29, the Thermalright Assassin X120 SE would be the better option. Each product has its strengths, catering to different preferences and needs in the competitive landscape of CPU coolers.
