Price Comparison
When considering price, the Thermalright Peerless Assassin 140 Black CPU Cooler is priced at C$54.90, making it the more budget-friendly option compared to the Thermalright Frozen Notte 240 Black ARGB V2 Water Cooling CPU Cooler, which costs C$63.90. The difference of C$9.00 may seem minor, but for consumers on a tight budget, it could be a deciding factor. Both products offer unique cooling capabilities, but the Peerless Assassin stands out for those looking for effective cooling without breaking the bank.
Cooling Performance
In terms of cooling performance, the Thermalright Frozen Notte 240 excels with its water-cooling design, featuring a high-performance cold head that can reach speeds of up to 5300 RPM. This design allows it to provide efficient cooling with a maximum airflow of 72.37 CFM. In contrast, the Thermalright Peerless Assassin, while effective, operates with dual fans at 1500 RPM, delivering a maximum airflow of 66.17 CFM. Thus, for users who prioritise maximum cooling efficiency, the Frozen Notte 240 is a superior choice.
Design and Build Quality
The build quality of both coolers is commendable, but they cater to different aesthetics. The Thermalright Frozen Notte 240 features an eye-catching ARGB lighting system that synchronises with the motherboard, allowing for a dazzling light display. This cooler's design incorporates a full copper mirror plane base and a high-strength acrylic top cover, ensuring durability and visual appeal. The Peerless Assassin, on the other hand, has a more utilitarian twin-tower design with pure copper heat pipes, which prioritises cooling efficiency over aesthetic features. If looks matter, the Frozen Notte 240 will likely be the preferred option.
Noise Levels
Noise levels are a crucial factor in any cooling solution, especially for users who value a quiet computing experience. The Thermalright Frozen Notte 240 operates with a maximum noise level of 27.7 dBA, which is relatively quiet for a water cooler. The Peerless Assassin, however, boasts a lower maximum noise level of 25.6 dBA, making it a slightly quieter choice when under load. For users who are sensitive to noise, this may sway them towards the Peerless Assassin, even if it sacrifices some cooling performance.
Installation Process
In terms of installation, both products offer compatibility across a wide range of CPU sockets, including Intel and AMD platforms. The Peerless Assassin comes equipped with an all-metal fastener system and multiple mounting options, making it user-friendly for installation within various chassis sizes. Meanwhile, the Frozen Notte 240 also promotes easy installation with its dual platform support and full metal black buckle. However, it is essential to note that the chassis width recommendation for the Frozen Notte is over 250mm, which may limit its compatibility with smaller builds. For users with space constraints, the Peerless Assassin may be the more practical choice.
Compatibility
Compatibility varies between the two coolers, with both supporting a wide range of Intel and AMD sockets. The Thermalright Peerless Assassin is compatible with Intel LGA1150 through LGA1851 and AMD AM4/AM5. The Frozen Notte 240, however, supports a broader range with compatibility extending to Intel LGA 1150 through LGA 2066 and AMD AM2 through AM5. This extensive compatibility makes the Frozen Notte 240 a versatile option for users with different CPU types, while the Peerless Assassin is more limited but still covers the most common sockets.
Aesthetic Appeal
For users who value aesthetic appeal in their builds, the Thermalright Frozen Notte 240 is the clear winner with its vibrant ARGB lighting system that provides a wide array of colour options and synchronisation capabilities with the motherboard. The lighting can create a stunning visual effect that enhances the overall look of the build. In contrast, the Peerless Assassin opts for a more traditional design without any RGB features. While it may not catch the eye as much, it focuses on performance and practicality, appealing to those who prefer a more understated look.
Which should you buy?
Ultimately, the choice between the Thermalright Peerless Assassin 140 Black CPU Cooler and the Thermalright Frozen Notte 240 Black ARGB V2 Water Cooling CPU Cooler depends on individual preferences and specific needs. If budget, noise levels, and a simpler installation process are your priorities, the Peerless Assassin is a solid choice at C$54.90. However, if you seek superior cooling performance, extensive compatibility, and a striking design with ARGB features, the Frozen Notte 240 at C$63.90 is worth the investment. Each cooler has its strengths, so your decision should align with your cooling requirements and aesthetic preferences.
