Overview of the ID-COOLING IS-55 Black and Thermalright Peerless Assassin 120 Vision MAX
The ID-COOLING IS-55 Black CPU Cooler is priced at $39.99, making it a budget-friendly option for users needing a low-profile cooler. In contrast, the Thermalright Peerless Assassin 120 Vision MAX costs $57.69, about 44% more than its counterpart. Both coolers are designed for Intel and AMD processors, but they cater to different needs and setups, which will be explored in detail.
Design and Aesthetics
The ID-COOLING IS-55 features a compact low-profile design with a height of only 57mm, making it ideal for small form factor builds like HTPCs and Mini-ITX setups. The Thermalright Peerless Assassin, however, boasts a dual-tower design that stands at 164mm tall. This height allows for better cooling performance but may not fit in smaller cases. While the ID-COOLING has a more straightforward appearance, the Thermalright adds a touch of flair with its magnetic top cover and a 5-inch IPS LCD screen that provides real-time system monitoring.
Cooling Performance
In terms of cooling capability, the ID-COOLING IS-55 is equipped with five heat pipes and a 120mm PWM fan, offering a maximum airflow of 54.6 CFM. The Thermalright Peerless Assassin excels with its dual fans and six heat pipes that rotate at a speed of 2150 RPM, delivering an airflow of 69 CFM. This makes the Thermalright about 26% more effective in airflow than the ID-COOLING, resulting in superior cooling performance, especially under heavy loads.
Noise Levels
Noise levels are a critical consideration for many PC builders. The ID-COOLING IS-55 offers a noise level range of 13.8-31.2 dB(A), ensuring a quiet operation during regular use. The Thermalright Peerless Assassin, on the other hand, operates at a maximum noise level of 27 dB(A), which is only slightly louder but still maintains a relatively quiet profile. Users who prioritize silent operation may find the ID-COOLING to be the better choice due to its lower minimum noise level.
RAM Compatibility
RAM compatibility can be a significant factor, especially in compact builds. The low-profile design of the ID-COOLING IS-55 enhances memory compatibility, allowing for greater flexibility in RAM height, particularly with Mini-ITX motherboards. The Thermalright Peerless Assassin's dual-tower design, while effective in cooling, might present clearance issues with taller RAM modules, despite its engineering aimed at accommodating GPU and RAM clearance. Thus, if RAM height is a concern, the ID-COOLING may be the more suitable option.
Installation and Compatibility
Both coolers are designed to be compatible with a range of Intel and AMD sockets. The ID-COOLING IS-55 supports Intel LGA 1851/1700/1200/1151/1150/1155/1156 and AMD AM5/AM4. The Thermalright Peerless Assassin features similar compatibility, supporting Intel lga1851/1700/115x and AM4/AM5. While both options are relatively straightforward to install, the ID-COOLING's low-profile design may make it easier to fit into tight spaces without obstructing other components, particularly in smaller cases.
Price Comparison
The ID-COOLING IS-55 is priced at $39.99, while the Thermalright Peerless Assassin is available for $57.69. This makes the ID-COOLING about 31% cheaper than the Thermalright. For budget-conscious builders or those seeking a reliable yet less expensive cooling solution, the ID-COOLING presents a compelling option without compromising too much on performance. In contrast, if you're willing to invest more for enhanced cooling and features, the Thermalright could be worth the added expense.
User Experience and Reviews
While specific user reviews and sales ranks are not provided, it's essential to consider what others say about these products. Generally, the ID-COOLING IS-55 receives praise for its compactness and effectiveness in small builds, making it a favorite among users with tight spaces. The Thermalright Peerless Assassin, with its advanced cooling technology and aesthetic features like the LCD screen, is likely appreciated by users who want not just performance but also a visually striking cooler.
Which should you buy?
Ultimately, the choice between the ID-COOLING IS-55 Black and the Thermalright Peerless Assassin 120 Vision MAX comes down to your specific needs and budget. If you’re looking for a compact, budget-friendly cooler that provides decent performance for smaller builds, the ID-COOLING is a great choice at $39.99. However, if you prioritize superior cooling, advanced features, and aesthetics, and are willing to spend more, the Thermalright at $57.69 offers a higher level of performance and visual appeal. Consider your build's requirements and your budget before making a final decision.
