Dimension comparison
Design and Build Quality
The Thermalright Peerless Assassin 120 SE V3 features a robust double-tower, dual-fan structure, while the Thermalright PS120SE ARGB has a similar design but boasts an additional heat pipe. The Peerless Assassin is made with a combination of aluminum and nickel-plated copper, which effectively aids in heat dissipation. Its six heat pipes are designed with AGHP technology, allowing for efficient thermal management. In contrast, the PS120SE ARGB incorporates seven heat pipes and utilizes S-FDB bearings for durability and performance. Both coolers are built with high-quality materials, yet the PS120SE ARGB stands out with its enhanced heat-pipe design.
Cooling Performance
Cooling performance is a critical aspect of CPU coolers, and both products offer impressive specifications. The Peerless Assassin can achieve a fan speed of 2000 RPM with an air volume of 70.84 CFM, while the PS120SE ARGB operates at a slightly lower maximum speed of 1500 RPM with an air flow of 66.17 CFM. Despite the lower fan speed, the PS120SE ARGB’s additional heat pipe compensates for this, promising effective heat dissipation across various configurations. Thus, while the Peerless Assassin might deliver higher RPMs, the PS120SE ARGB's design with one more heat pipe could provide comparable cooling, especially under heavier loads.
Noise Levels
When it comes to noise levels during operation, the Thermalright PS120SE ARGB has a maximum noise level of 25.6 dB, making it quieter than the Peerless Assassin, which operates at up to 29.8 dB. Lower noise levels can greatly enhance the overall user experience, particularly in quiet environments or during gaming sessions. This 14% difference in noise output positions the PS120SE ARGB as a more appealing option for users sensitive to sound.
Compatibility
Both CPU coolers boast wide compatibility with modern Intel and AMD platforms. The Peerless Assassin supports Intel LGA 1851/1700/1150/1151/1155/1156/1200 and AMD AM4/AM5, while the PS120SE ARGB covers the same Intel and AMD sockets. This extensive compatibility ensures users can install either cooler on a variety of systems without significant issues. However, the Peerless Assassin’s installation guide mentions the need to use the original backplate for AMD setups, which may complicate installation for some users.
Aesthetics and LED Features
In terms of aesthetics, the PS120SE ARGB shines with its addressable RGB lighting capabilities. It can display up to 17 different modes of light effects, creating a vibrant visual appeal that can be synchronized with compatible motherboards. The Peerless Assassin, while sleek and professional in its design, lacks such RGB features. For users who prioritize visual flair in their builds, the PS120SE ARGB is a clear winner, offering a customizable aesthetic that enhances the overall look of a gaming setup.
Price Comparison
The Thermalright Peerless Assassin 120 SE V3 is priced at $35.90, while the PS120SE ARGB is slightly cheaper at $34.94, making it about 3% less expensive. This small price difference may not heavily influence purchasing decisions, but for budget-conscious consumers, every dollar counts. The PS120SE ARGB's combined features, including its enhanced cooling capabilities and RGB lighting, may provide a better value proposition at a lower price point.
User Feedback and Market Position
Both coolers are relatively new to the market, and while there are no specific sales ranks available, their features suggest strong performance in the competitive CPU cooler landscape. User feedback tends to highlight the effective cooling capabilities of both products, though the PS120SE ARGB might attract more attention due to its additional heat pipe and aesthetic features. As such, those looking for performance combined with visual appeal may gravitate towards the PS120SE ARGB.
Which should you buy?
In conclusion, both the Thermalright Peerless Assassin 120 SE V3 and the PS120SE ARGB are excellent choices for CPU cooling, but they cater to slightly different preferences. If you prioritize maximum cooling performance and don’t mind a bit of extra noise, the Peerless Assassin is a solid option. However, if you’re looking for a cooler that balances performance with aesthetics and quieter operation, the PS120SE ARGB stands out as the more attractive choice, especially considering its lower price and enhanced features.
