ID-COOLING FROZN A620 PRO SE - Blackout Dual-TowerThermalright Assassin X 120R Digital ARGB Black

Price Comparison

The ID-COOLING FROZN A620 PRO SE is priced at $29.99, while the Thermalright Assassin X 120R is more budget-friendly at $22.90, making it about 17% cheaper. This price difference could be significant for users looking to maximize their budget for a CPU cooler. While the ID-COOLING model offers a dual-tower design and a higher heat pipe count, the Thermalright provides solid performance at a lower price point. For gamers and PC builders on a tighter budget, the lower price of the Thermalright could be more appealing without sacrificing quality.

Cooling Performance

In terms of cooling performance, the ID-COOLING FROZN A620 PRO SE features six Ф6mm heat pipes, which contribute to efficient heat dissipation. It includes two 120mm PWM fans that allow for quiet operation, with a maximum noise level of 27.2dB(A). On the other hand, the Thermalright Assassin X 120R employs four heat pipes with a fan speed that can reach 2000 RPM, providing robust cooling as well. While both coolers are designed to maintain optimal CPU temperatures, the additional heat pipes in the ID-COOLING model may provide a slight edge in extreme cooling scenarios.

Aesthetic Appeal

Aesthetically, the ID-COOLING FROZN A620 PRO SE is designed as a blackout cooler, which blends well with dark-themed builds. Its sleek design and dual-tower configuration contribute to a modern look. Conversely, the Thermalright Assassin X 120R features a digital screen on the top cover and ARGB lighting, allowing users to customize the visual effects to their liking. This can be particularly appealing for those who prioritize aesthetics in their PC builds. Therefore, if visual customization and dynamic lighting are essential, the Thermalright could be the better choice.

Compatibility

When it comes to compatibility, the ID-COOLING FROZN A620 PRO SE has a height of 157mm, allowing it to fit comfortably in most tower cases. It offers 40mm clearance for standard RAM and can accommodate up to 63mm height with cut-out fins. The Thermalright Assassin X 120R is slightly shorter at 151mm, which also allows it to fit in a wide range of cases. Both coolers support Intel LGA1700/1851/1200/115X and AMD AM4/AM5 sockets, ensuring compatibility with modern processors. While both options are compatible with most systems, the ID-COOLING offers slightly more RAM clearance, which could be beneficial for users with taller RAM modules.

Noise Levels

The ID-COOLING FROZN A620 PRO SE boasts a low noise level of 27.2dB(A), making it a quiet option for performance enthusiasts who value a noise-free environment. The dual 120mm PWM fans are specifically designed for low-noise operations. In contrast, the Thermalright Assassin X 120R utilizes a 2000 RPM PWM fan, which, while efficient, may produce slightly more noise depending on the workload. For users who prioritize silence, the ID-COOLING may be the preferred choice. However, those who favor performance and are willing to tolerate a bit more noise might lean towards the Thermalright.

Installation Process

Both coolers are designed for relatively straightforward installation processes, but the specifics can vary. The ID-COOLING FROZN A620 PRO SE's design allows for easy mounting on both Intel and AMD systems, which is crucial for users who may not have extensive experience with CPU cooler installations. The Thermalright Assassin X 120R also offers a user-friendly installation experience, especially with its digital screen feature that adds an extra layer of interaction. While both coolers are manageable for most users, the simplicity of the ID-COOLING's mounting system may appeal to beginners.

Build Quality and Durability

Build quality is essential in ensuring longevity and reliability in CPU coolers. The ID-COOLING FROZN A620 PRO SE features a dual-tower heatsink and is constructed with materials that promote durability. Its six heat pipes are designed to efficiently absorb heat, ensuring longevity. The Thermalright Assassin X 120R, on the other hand, is built with UL CLASSA safety insulation-grade materials and silicone corner pads, which help to minimize vibrations and noise. Both coolers offer solid build quality, but the materials used in the Thermalright may provide superior vibration dampening, enhancing its durability over time.

Which should you buy?

Choosing between the ID-COOLING FROZN A620 PRO SE and the Thermalright Assassin X 120R ultimately depends on your specific needs and preferences. If you prioritize maximum cooling performance, aesthetic appeal with ARGB features, and a lower price point, the Thermalright Assassin X 120R at $22.90 is a compelling choice. However, if you seek a more robust cooling solution with a quieter operation and enhanced RAM compatibility, the ID-COOLING FROZN A620 PRO SE at $29.99 provides excellent value. Consider your budget, cooling requirements, and aesthetic preferences to make the best choice for your build.
