Dimension comparison
Design and Build Quality
When it comes to design and build quality, the Thermalright Peerless Assassin 120 SE CPU Cooler features a dual tower heatsink configuration made from aluminum and copper. This construction aims to maximise heat exchange efficiency, crucial for maintaining optimal CPU temperatures. The cooler's dimensions are 125(L)x135(W)x155(H)mm, making it a compact choice for various builds. On the other hand, the Thermalright Aqua Elite 240 V3 Liquid CPU Cooler incorporates a 240mm radiator, which provides a larger surface area for heat dissipation. Its octagonal pump head and protective mesh water pipe contribute to its durability and aesthetic appeal, enhancing both performance and visual impact.
Cooling Performance
The Thermalright Aqua Elite 240 V3 is designed for superior cooling performance, boasting a maximum pump speed of 3,300 RPM, which is significantly higher than the Peerless Assassin's fan speed of 1,550 RPM. This higher RPM allows the Aqua Elite to dissipate heat more effectively, making it a better choice for overclocked CPUs or high-performance systems. Both coolers utilise dual fans with a maximum airflow of 66.17 CFM, but the Aqua Elite's liquid cooling system offers more efficient thermal management in demanding scenarios.
Noise Levels
In terms of noise levels, the Thermalright Aqua Elite operates at a maximum noise level of 23 dBA, making it quieter than the Peerless Assassin, which has a rated noise level of 25.6 dBA. This difference may seem minimal, but in a quiet environment or during intensive tasks, the Aqua Elite's lower noise output can provide a more pleasant computing experience. Therefore, if silence is a priority for you, the Aqua Elite might be the better option.
Installation Process
Installation is simplified for both CPU coolers, but they cater to different preferences. The Peerless Assassin 120 SE uses the SS2 install system with a metal pressure plate, while the Aqua Elite includes a comprehensive AIO cooler compatibility package for both Intel and AMD sockets. The Aqua Elite's design is aimed at providing easy installation with clear instructions, allowing users to set it up without much hassle. This focus on user-friendliness might appeal more to those new to building PCs or those looking for a quicker setup.
Aesthetic Appeal
Aesthetic appeal is another area where both coolers shine, but they do so in different ways. The Peerless Assassin features colourful ARGB lighting effects with its dual fans, creating a vibrant look to complement modern builds. Conversely, the Aqua Elite takes aesthetic appeal a step further with its ARGB sync capabilities, allowing for a synchronised lighting experience with other components. This can be particularly appealing for gamers and PC enthusiasts who prioritise visual integration in their setups.
Price Comparison
Pricewise, the Thermalright Peerless Assassin 120 SE is more budget-friendly, priced at C$48.90. In contrast, the Aqua Elite comes in at C$71.90, reflecting its more advanced technology and greater cooling capabilities. The C$23 difference may seem justifiable for users seeking enhanced performance, particularly in high-demand situations. However, for those on a tighter budget or with lower cooling needs, the Peerless Assassin presents an excellent value without compromising too much on performance.
Compatibility
In terms of compatibility, both coolers support a range of Intel and AMD sockets. The Peerless Assassin is compatible with Intel’s LGA1150/1151/1155/1156/1200/1700/1851 and AMD’s AM4/AM5 sockets, while the Aqua Elite supports a broader range, including Intel’s LGA2011/2066 in addition to the same sockets as the Peerless. This makes the Aqua Elite more versatile for users who might upgrade their systems in the future. However, users must ensure they have the original motherboard backplate for the Peerless Assassin during installation on AM4 and AM5.
Which should you buy?
Ultimately, the choice between the Thermalright Peerless Assassin 120 SE and the Aqua Elite 240 V3 depends on your specific needs. If you are looking for a cost-effective, efficient air cooler that offers adequate performance for moderate gaming and everyday tasks, the Peerless Assassin is a solid choice. Conversely, if you require superior cooling for high-performance tasks, such as gaming at high settings or overclocking, the Aqua Elite’s advanced liquid cooling design and lower noise levels make it worth the investment.
