Price Comparison
The Thermalright Peerless Assassin 120 SE V2 CPU Cooler is priced at C$54.90, making it the more budget-friendly option compared to the Thermalright Frozen Notte 240 Black ARGB Water Cooling CPU Cooler, which retails for C$62.90. The difference of C$8 may seem minimal, but for consumers on a tight budget, every dollar counts. With the Peerless Assassin offering solid performance at a lower price point, it may appeal more to those looking for value without sacrificing quality.
Cooling Performance
When it comes to cooling performance, the Thermalright Frozen Notte 240 stands out with its water cooling technology. It features a high-performance cold head that operates at speeds up to 5300 RPM, significantly higher than the Peerless Assassin's maximum fan speed of 1850 RPM. The Frozen Notte uses a full copper mirror plane base and a 240 mm aluminum fin cold plate to enhance cooling efficiency, which could be particularly beneficial for users with high-performance CPUs. However, the Peerless Assassin offers a respectable TDP of up to 265 watts, which is adequate for most users without overclocking.
Design and Build Quality
In terms of design, the Thermalright Peerless Assassin boasts a solid build with aluminum fins and a pure copper base, ensuring durability. Its dimensions are 125mm x 135mm x 155mm and it weighs 610 grams, making it a compact yet robust option. The Frozen Notte, with its water-cooling system, has a more intricate design featuring a high-strength acrylic top cover and a cooling block that enhances its aesthetic appeal, especially with its ARGB lighting. The added visual flair of the Frozen Notte may attract gamers and PC builders who value aesthetics as much as performance.
Noise Levels
Noise levels are an essential consideration for many users. The Peerless Assassin has a noise level of up to 29.5 dB(A), which is relatively quiet for a CPU cooler. In comparison, the Frozen Notte operates at a slightly quieter level of 27.7 dB(A). This marginal difference may be negligible for some, but for users seeking a silent operation, the Frozen Notte could be the preferred choice, especially during intense gaming sessions or heavy workloads.
Compatibility
Both coolers offer extensive compatibility with various CPU sockets, but the Thermalright Frozen Notte provides slightly broader support. The Peerless Assassin is compatible with Intel LGA 1851/1700/1200/115X and AMD AM4/AM5, while the Frozen Notte supports a wider range including Intel LGA 1150/1151/1155/1156/1200/1700/1851/2011/2066 and AMD AM4/AM5/AM2/AM2+/AM3/AM3+/FM1/FM2/FM2+. This makes the Frozen Notte a more versatile option for users with different setups or those who may upgrade their systems in the future.
Installation Ease
When it comes to installation, both products are designed to be user-friendly. The Peerless Assassin includes metal fasteners for Intel and AMD platforms, ensuring that users can easily install it according to the provided instructions. The Frozen Notte also features a dual platform full metal black buckle, making installation straightforward. However, the Peerless Assassin's simpler design may appeal to those who prefer a no-fuss installation process, while the Frozen Notte's complexity could be a consideration for those who appreciate advanced technology.
Aesthetic Features
Aesthetic appeal is an important factor for many PC builders, and the Thermalright Frozen Notte excels in this area with its ARGB lighting. The lighting is synchronised with the PWM fans and offers a range of colour effects that can enhance the overall look of a gaming rig. In contrast, the Peerless Assassin has a more utilitarian design without any RGB features. For users who prioritise aesthetics alongside performance, the Frozen Notte's lighting capabilities could be a significant deciding factor.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 SE V2 and the Thermalright Frozen Notte 240 ultimately depends on your specific needs and preferences. If you're looking for a cost-effective solution that delivers solid cooling performance with straightforward installation, the Peerless Assassin at C$54.90 is an excellent choice. However, if budget is less of a concern and you desire superior cooling capabilities, extensive compatibility, and visually appealing features like ARGB lighting, the Frozen Notte at C$62.90 may be worth the investment. Each product has its strengths, making them suitable for different types of users and setups.
