Overview of the ID-COOLING FROZN A620 PRO SE and Thermalright Peerless Assassin 120 Black

The ID-COOLING FROZN A620 PRO SE is priced at $29.99, while the Thermalright Peerless Assassin 120 Black is available for $38.90, making the former about 23% cheaper. Both coolers are designed for high-performance cooling, featuring dual towers and multiple heat pipes, but they offer unique advantages that cater to different needs.

Design and Aesthetic Appeal

The ID-COOLING FROZN A620 PRO SE boasts a sleek blackout design that allows it to blend seamlessly into various computer cases, particularly those with dark interiors. This aesthetic might appeal to gamers and PC builders looking for a cohesive look. In contrast, the Thermalright Peerless Assassin 120 Black also features a stylish black finish, but its design focuses more on functionality with an asymmetrical layout that ensures it does not obstruct the first graphics card slot. Both coolers have a height of 157mm, making them compatible with most tower cases.

Cooling Performance

When it comes to cooling performance, the ID-COOLING FROZN A620 PRO SE is equipped with dual 120mm PWM fans and six Ф6mm copper heat pipes that effectively dissipate heat. It operates with a maximum noise level of 27.2 dB(A), which is relatively quiet for a CPU cooler. The Thermalright Peerless Assassin 120 Black, on the other hand, also comes with dual 120mm PWM fans but boasts a slightly lower maximum noise level of 25.6 dB(A). Both coolers are designed for extreme cooling performance, but the Thermalright model may offer a quieter operation under load.

Installation and Compatibility

Both coolers are designed for easy installation and compatibility with a range of CPU sockets. The ID-COOLING FROZN A620 PRO SE supports Intel LGA1700, LGA1851, LGA1200, LGA115X, and AMD AM4/AM5 sockets, making it versatile for various builds. Similarly, the Thermalright Peerless Assassin 120 Black supports a wide array of Intel and AMD sockets, including LGA1150, LGA1151, LGA1155, LGA1156, LGA1200, LGA1700, LGA2066, and AMD AM4/AM5. Both products cater to most modern CPUs, ensuring broad compatibility for users.

Noise Levels and Fan Operation

The ID-COOLING FROZN A620 PRO SE operates at a noise level of 27.2 dB(A) at maximum capacity, which is commendable for a dual-fan setup. The PWM functionality allows for automatic speed adjustments, resulting in quieter operation during less intense tasks. In contrast, the Thermalright Peerless Assassin 120 Black offers an even quieter performance with a maximum noise level of 25.6 dB(A). This slight difference in noise levels may be significant for users who prioritize a noise-free environment.

Heat Dissipation Technology

The ID-COOLING FROZN A620 PRO SE utilizes six Ф6mm heat pipes for efficient heat absorption and transfer to the heatsink. This design allows for better heat dissipation, ensuring that the CPU remains cool even during demanding tasks. On the other hand, the Thermalright Peerless Assassin 120 Black incorporates AGHP technology to enhance heat dissipation further, making it capable of handling a thermal design power (TDP) of up to 245W. This capability might give it an edge for users with high-performance CPUs that generate more heat.

Weight and Build Quality

The ID-COOLING FROZN A620 PRO SE weighs around 1.02kg, which is typical for dual-tower coolers, while the Thermalright Peerless Assassin 120 Black also weighs in at about 1.02kg. Both units are constructed with quality materials that ensure durability and effective cooling. However, the Thermalright cooler features an aluminum heatsink cover, which may contribute to its overall reliability and aesthetic appeal.

Which should you buy?

When deciding between the ID-COOLING FROZN A620 PRO SE and the Thermalright Peerless Assassin 120 Black, the choice ultimately depends on your specific needs and budget. The ID-COOLING FROZN A620 PRO SE is a more affordable option at $29.99, providing solid performance with an attractive design. However, if you prioritize quieter operation and slightly better cooling technology with AGHP, the Thermalright Peerless Assassin 120 Black, though more expensive at $38.90, offers features that may justify the higher price for many users. Each cooler has its strengths, making them both worthy contenders in the CPU cooler market.
