R-AK620-BKNNMT-G-1

A powerful tower cooler with a dense fin arrangement, two active fans, and an impressive heat dissipation capacity of around 260W, allows for effective cooling of high-end and extreme multi-core processors. The core of the cooling tower includes six U-shaped copper heat pipes of standard diameter, which are firmly connected to a massive nickel-plated base. These pipes efficiently distribute heat across the extensive area of the aluminum radiator, allowing efficient heat dissipation even during intensive automatic or manual CPU overclocking.

The cooling system provides not only excellent performance but also offers flexibility in settings. Thanks to the use of two fans with dynamic speed regulation, the Deepcool AK620 Zero Dark automatically adapts to the CPU temperature, ensuring an optimal balance between noise levels and heat. The declared fan speed ranges from 500 to 1850 RPM, with a maximum noise level not exceeding 28 dB.

The manufacturer guarantees full compatibility with motherboards equipped with AMD AM4, AM3(+), AM2(+), FM2, FM1, and Intel LGA2066, 2011(v3), 115X, 1200, and 1700 processor sockets. A feature of installation is the necessity of using the included backplate, which may require the removal of the motherboard. In conclusion, the Deepcool AK620 can be a balanced solution for medium and high-performance systems, offering gamers and enthusiasts a very appealing combination of efficiency, reliability, and quietness.

Model overview based on user reviews  
The Deepcool AK620 Zero Dark is an active CPU cooler designed for efficient cooling with a maximum TDP of 260 W. It features a double-tower design and includes two 120 mm fans with a noise level of 28 dB. The cooler is praised for its appearance and effective cooling capabilities, especially with processors like the Ryzen 7 7700 and i5 13400, where it maintains temperatures as low as 44 degrees. However, some users suggest that for modern systems, water cooling might be a better option. There are concerns about the noise level at high RPM and the longevity of the fans, which might need replacement after a couple of years. Despite these issues, it remains a good choice for those seeking a reliable air cooling solution, although the price might be a consideration for some.

good model, like it
17 December 2023 
Everything is okay, a good cooler, but it's noisy at high RPM. With i5 13400, it peaks at 44 degrees.
Overall, it's okay, but I think in about 2 years the fans will be done for.
Price, loud
