ID-COOLING IS-55 Black CPU Cooler Low Profile vs Thermalright Assassin X120 Refined SE CPU Air

Overview of the Products

The ID-COOLING IS-55 Black CPU Cooler is designed for low-profile applications, while the Thermalright Assassin X120 Refined SE CPU Air Cooler is a more traditional option with a taller profile. The former is priced at $39.99, making it about 123% more expensive than the latter, which retails for $17.90. Understanding the features and performance of each cooler can help you decide which one best fits your needs.

Design and Build Quality

The ID-COOLING IS-55 features a compact design with a height of only 57mm, making it ideal for small form factor builds or HTPCs. Its low-profile design allows for excellent RAM compatibility, particularly in Mini-ITX motherboards. In contrast, the Thermalright Assassin X120 measures 148mm in height and may not fit as easily in tighter cases. However, it boasts a more robust build with an aluminum heatsink cover and four heat pipes, providing a sturdier structure for effective heat dissipation.

Cooling Performance

When it comes to cooling performance, the ID-COOLING IS-55 is equipped with five heat pipes and a 120mm PWM fan, delivering a maximum airflow of 54.6 CFM. The fan operates at a noise level of 13.8 to 31.2 dB(A), ensuring a quiet operation even under load. On the other hand, the Thermalright Assassin X120's TL-C12C PWM fan can achieve a higher airflow of 66.17 CFM while maintaining a noise level of 25.6 dB(A). This suggests that the Thermalright may provide better cooling performance, especially for higher TDP CPUs.

Compatibility

Both coolers offer broad compatibility with Intel and AMD platforms. The ID-COOLING IS-55 supports Intel LGA 1851/1700/1200/1151/1150/1155/1156 and AMD AM5/AM4 sockets. Similarly, the Thermalright Assassin X120 is compatible with Intel LGA 1150/1151/1155/1156/1200/1700/1851 and AMD AM4/AM5. This makes either cooler a suitable choice for a variety of builds, ensuring you won’t have compatibility issues with modern CPUs.

Noise Levels

Noise levels are an essential consideration for many PC builders. The ID-COOLING IS-55 operates at a range of 13.8 to 31.2 dB(A), allowing for a virtually silent experience during light use and acceptable noise levels during heavy loads. In contrast, the Thermalright Assassin X120 operates at a maximum noise level of 25.6 dB(A). While still relatively quiet, it may not be as silent as the ID-COOLING during low-load conditions. If a noiseless environment is a priority, the ID-COOLING may have the edge.

Price Comparison

At $39.99, the ID-COOLING IS-55 is significantly more expensive than the Thermalright Assassin X120, which is priced at $17.90. This price difference of about $22.09 highlights a cost-saving opportunity if budget constraints are a concern. The Thermalright provides solid performance at a lower price point, making it an attractive option for those looking to save money without compromising essential cooling capabilities.

Brand Reputation

ID-COOLING and Thermalright are both reputable brands in the cooling market. ID-COOLING is known for focusing on compact cooling solutions, while Thermalright has over 20 years of experience in developing cooling products and accessories. Thermalright's established presence in the market suggests a level of reliability and trustworthiness, which can be an important factor when choosing a CPU cooler.

Which should you buy?

Choosing between the ID-COOLING IS-55 and the Thermalright Assassin X120 ultimately depends on your specific needs. If you're looking for a compact, low-profile cooler with excellent RAM compatibility and quieter operation, the ID-COOLING IS-55 might be the better choice despite its higher price. However, if you prioritize cooling performance and cost-effectiveness, the Thermalright Assassin X120 stands out with a significantly lower price and a higher airflow capacity. Consider your case size, budget, and cooling requirements before making your decision.
