Dimension comparison
Brand Overview
Both the Thermalright Assassin X 120R SE Plus and the Thermalright PS120SE ARGB are products from Thermalright, a reputable brand with over 20 years of experience in the computer accessory market. Both coolers reflect the brand’s commitment to quality and innovation, but they cater to slightly different user needs.
The Assassin X 120R SE Plus is designed for users seeking efficient cooling with a focus on low noise levels. In contrast, the PS120SE ARGB targets gamers and PC builders who also value aesthetics alongside performance, featuring stunning ARGB lighting. While both coolers are backed by Thermalright’s strong reputation, their distinct features make them suitable for different audiences.
Cooling Performance
When it comes to cooling performance, the Thermalright Assassin X 120R SE Plus boasts four 6mm heat pipes and a dual-fan configuration that can produce a maximum airflow of 66.17 CFM. This setup effectively manages heat dissipation while maintaining a noise level of ≤25.6 dB(A), making it a strong contender for those seeking efficient cooling without excessive noise.
On the other hand, the PS120SE ARGB features upgraded 7x6mm heat pipes and also reaches a maximum airflow of 66.17 CFM with a similar noise level of ≤25.6 dB(A). Both coolers are designed to provide reliable cooling performance, but the upgraded technology in the PS120SE may offer slightly better thermal management under load due to the enhanced heat pipe configuration.
Fan Specifications
The Assassin X 120R SE Plus utilises two PWM fans, the TL-C12C and TL-C12RB V2, with speeds reaching up to 1550 RPM and 1500 RPM, respectively. This efficient dual-fan setup helps achieve optimal cooling while keeping noise to a minimum.
In comparison, the PS120SE ARGB is equipped with the TL-C12B-S V2 fans, which have a maximum RPM of 1500. While the PS120SE has slightly lower RPMs, it compensates with its advanced ARGB lighting and fan design, making it visually appealing while still delivering effective cooling performance.
Installation Compatibility
Both the Thermalright Assassin X 120R SE Plus and the PS120SE ARGB are compatible with a broad range of CPU sockets. The Assassin X supports Intel sockets 1150/1151/1155/1156/1200/1700/17XX and AMD sockets AM4/AM5, making it versatile for many builds.
The PS120SE ARGB also supports a similar range of Intel sockets (LGA1700/1851/1150/1151/1155/1156/1200) and AMD sockets (AM4/AM5), ensuring that users can easily integrate either cooler into their systems. This compatibility highlights that both coolers are well-suited for a variety of setups without compromising on installation ease.
Build Quality
The build quality of both coolers reflects Thermalright's commitment to durability. The Assassin X 120R SE Plus utilises industrial-strength PBT + PC materials, ensuring a robust design with an extended service life of up to 20,000 hours. The S-FDB bearings further enhance the longevity and reliability of this cooler.
Similarly, the PS120SE ARGB also features high-quality materials, including anodised black frosted top and aluminum fins, along with a finely carved pure copper base. This construction also supports a long service life and effective heat dissipation, making both coolers reliable options for long-term use.
Aesthetic Appeal
One major differentiating factor between the two coolers is their aesthetic design. The Thermalright Assassin X 120R SE Plus has a more traditional, sleek look, making it an excellent choice for users who prefer a minimalist style in their builds.
Conversely, the PS120SE ARGB stands out with its vibrant ARGB lighting. It features a high-brightness LED fan blade that can produce up to 17 different lighting modes, allowing users to customise their cooling solution to match their overall build aesthetics. For those prioritising visual appeal alongside performance, the PS120SE ARGB is the more attractive option.
Price Point
The Thermalright Assassin X 120R SE Plus is priced at C$25.59, making it a budget-friendly option for those who need effective cooling without breaking the bank. In contrast, the Thermalright PS120SE ARGB is priced at C$63.68, which reflects its additional features and aesthetic enhancements.
This significant price difference of C$38.09 indicates that while both products are from the same brand and offer similar cooling capabilities, the PS120SE ARGB comes with added functionalities and design elements that may justify the higher cost for certain users.
Which should you buy?
Choosing between the Thermalright Assassin X 120R SE Plus and the PS120SE ARGB ultimately depends on your specific needs. If you prioritise efficient cooling performance at an economical price, the Assassin X 120R SE Plus is an excellent choice. However, if you are looking for a cooler that combines performance with stunning visual effects, the PS120SE ARGB is worth the extra investment. Both coolers are solid options, but your final decision should align with your performance requirements and aesthetic preferences.
