Dimension comparison
Overview
In this comparison, we will evaluate the ARCTIC P12 Pro A-RGB - 3 Pack and the Thermalright Assassin X120 SE ARGB CPU Air Cooler to help you decide which cooling solution is more suitable for your needs. The former is priced at £24.99 for a pack of three fans, while the latter is available for £16.29 as a standalone CPU cooler. Both products promise efficient cooling, but they cater to different applications and preferences.
Design and Build Quality
The ARCTIC P12 Pro A-RGB features a new fan blade design that optimises performance while maintaining low noise levels. This focus on design is crucial as the fan operates efficiently even in environments with resistance, such as dense radiators or mesh structures. On the other hand, the Thermalright Assassin X120 SE is a CPU air cooler constructed from aluminium with a weight of 0.63 kg. Its dimensions are 120(L)x71(W)x148(H)mm, making it a compact option for medium-sized cases. While both products exhibit thoughtful design, the P12 Pro's innovative blade structure may provide better airflow in restrictive conditions.
Cooling Performance
The cooling capabilities of both products are noteworthy but tailored for different purposes. The ARCTIC P12 Pro can operate at speeds up to 3000 rpm through its PWM control, offering high static pressure for demanding cooling tasks. This makes it particularly effective for high-performance builds. Conversely, the Thermalright Assassin X120 SE features a fan speed of up to 1550 rpm, achieving a maximum airflow of 66.17 CFM. While the Assassin X120 SE is designed to cool CPUs effectively, the P12 Pro's higher RPM potential suggests it might be more versatile for various cooling needs.
Noise Levels
When it comes to noise levels, the ARCTIC P12 Pro is designed for quiet operation, utilising a smooth-running fluid dynamic bearing (FDB) that minimizes sound during use. The P12 Pro aims for a noise level that remains unobtrusive even under load. In contrast, the Thermalright Assassin X120 SE has a specified noise level of 25.6 dB(A), making it relatively quiet but not as silent as the P12 Pro at higher speeds. If a whisper-quiet environment is a priority, the P12 Pro may be the better choice.
Installation and Compatibility
Both products offer straightforward installation processes but cater to different setups. The ARCTIC P12 Pro is a fan product, requiring a case or cooling system to install, while the Thermalright Assassin X120 SE is a CPU cooler that includes metal fasteners for both Intel and AMD platforms. The Assassin X120 SE supports a range of sockets such as LGA 1150/1151/1155/1156/1200/1700/1851 for Intel and AM4/AM5 for AMD, making it versatile for various CPUs. If you're building or upgrading a system, the compatibility of the Assassin X120 SE may be a significant factor.
Aesthetics
In terms of aesthetics, the ARCTIC P12 Pro boasts A-RGB lighting, allowing for vibrant colour customisation that can enhance the visual appeal of any PC build. This feature is especially attractive to gamers and PC enthusiasts who want to showcase their systems. Meanwhile, the Thermalright Assassin X120 SE also delivers ARGB lighting effects, ensuring that it can fit seamlessly within a build that prioritises RGB aesthetics. Both products cater to users who appreciate a visually appealing setup, but the ARCTIC P12 Pro's focus on performance may make it a slightly more appealing choice.
Brand Reputation
Both ARCTIC and Thermalright have established reputations in the cooling market. ARCTIC is known for its focus on providing high-performance cooling solutions at competitive prices. The P12 Pro exemplifies this ethos with its powerful performance and quiet operation. On the other hand, Thermalright has over 20 years of experience and is well-regarded for its innovative designs and reliable products. Their commitment to research and development is evident in the Assassin X120 SE, which aims to deliver effective cooling solutions for a range of setups. Understanding brand reputation can help shape your decision based on previous experiences and product reliability.
Price Point
The ARCTIC P12 Pro A-RGB is priced at £24.99 for a three-pack, making it a more cost-effective option for users looking to enhance their case cooling significantly. In comparison, the Thermalright Assassin X120 SE is available at £16.29, making it an affordable choice for a CPU cooler. When considering value, the P12 Pro offers three fans for a slightly higher price, while the Assassin X120 SE provides a standalone solution that may be more suitable for those focused solely on CPU cooling.
Which should you buy?
Deciding between the ARCTIC P12 Pro A-RGB and the Thermalright Assassin X120 SE ultimately depends on your specific cooling needs. If you require versatile and powerful fans that can be used in various configurations, the P12 Pro is an excellent choice with its superior RPM and airflow capabilities.
