Dimension comparison
Price Comparison
The Thermalright Peerless Assassin 120 SE CPU Cooler is priced at C$48.90, while the Thermalright Frozen Notte 360 White ARGB V2 Water Cooling CPU Cooler costs C$71.90. This significant price difference of C$23 reflects the different cooling technologies and features offered by each cooler. The Peerless Assassin is an air cooler which typically comes at a lower price point, while the Frozen Notte utilises water cooling technology, which generally incurs higher manufacturing and material costs. For users on a budget or those looking for a straightforward cooling solution, the Peerless Assassin presents a more economical choice.
Cooling Performance
When it comes to cooling efficiency, the Thermalright Frozen Notte 360 stands out due to its advanced water cooling system. It features a high-performance cold head that utilizes a copper base for effective heat dissipation and can reach fan speeds of up to 5300 RPM, ensuring optimal cooling under heavy loads. In contrast, the Peerless Assassin operates with a dual tower heatsink configuration and includes two ARGB fans that can reach speeds of 1550 RPM. While both coolers are effective, the Frozen Notte's water cooling design typically provides superior performance in maintaining lower CPU temperatures during intensive tasks.
Design and Aesthetics
The Thermalright Frozen Notte 360 not only excels in performance but also in aesthetics, featuring synchronised ARGB lighting on both the fans and the water block. This allows users to create a visually striking setup with a dazzling light display, enhancing the overall look of a gaming rig. The Peerless Assassin, while functional and effective, offers a simpler design with ARGB effects limited to its fans. Those who prioritise aesthetics and wish to create a visually cohesive build may find the Frozen Notte more appealing, especially given the ability to synchronise lighting effects with other components.
Installation Process
For installation ease, the Thermalright Peerless Assassin 120 SE is designed with an SS2 install system, making it straightforward to mount on compatible Intel and AMD motherboards. However, users must note that when installing on AM4 and AM5 motherboards, the original backplate is necessary. The Frozen Notte 360 also offers a user-friendly installation experience, compatible with a broader range of Intel and AMD sockets, including LGA 2011 and 2066. However, its larger size may require a case width of at least 250mm, which could limit compatibility with smaller cases. Those seeking an easy installation experience may find both options manageable, but the Frozen Notte's size requirements should be considered.
Noise Levels
In terms of noise levels, the Thermalright Peerless Assassin 120 SE operates at a maximum noise level of 25.6 dB(A), making it a relatively quiet option for users who are sensitive to sound. The Frozen Notte 360, while also designed to operate quietly, has a slightly higher maximum noise level of 27.7 dB(A) when the fans are running at full speed. The difference in noise output may be negligible for some users, but for those prioritising a noiseless environment, the Peerless Assassin could be a better fit, especially in quieter setups.
Compatibility
Compatibility is crucial when choosing a CPU cooler, and both the Thermalright Peerless Assassin 120 SE and the Frozen Notte 360 cater to a wide array of Intel and AMD sockets. The Peerless Assassin supports Intel LGA 1150, 1151, 1155, 1156, 1200, 1700, and 1851, alongside AMD AM4 and AM5. The Frozen Notte 360 supports a broader range of sockets, including LGA 2011 and 2066, making it suitable for high-end builds. However, users must ensure their cases can accommodate the size of the Frozen Notte. For users with specific motherboard requirements, the Frozen Notte offers more versatility.
Durability and Lifespan
The Thermalright Frozen Notte 360 is engineered for longevity, with its water cooling head designed to last up to 40,000 hours. This durability is attributed to its high-quality copper base and robust construction, ensuring reliable performance over time. The Peerless Assassin does not specify a lifespan but is built with durable materials, including aluminum and copper, which are standard in quality air coolers. For users looking for a long-lasting cooling solution, the Frozen Notte presents a compelling advantage due to its extended lifespan.
Which should you buy?
Ultimately, the choice between the Thermalright Peerless Assassin 120 SE and the Frozen Notte 360 White ARGB V2 Water Cooling CPU Cooler hinges on your specific needs and preferences. If you are on a budget and seeking a straightforward, effective air cooling solution, the Peerless Assassin at C$48.90 is an excellent choice. However, if you desire superior cooling performance, enhanced aesthetics, and broader compatibility, the Frozen Notte 360, priced at C$71.90, is worth the investment. Both coolers are high-quality offerings from Thermalright, but your decision should be guided by your cooling requirements, case compatibility, and budget constraints.
