When building a PC, one of the most important things to consider is the CPU cooler. The CPU generates a lot of heat, and if it’s not cooled properly, it can lead to reduced performance, instability, and even damage. In this comparison, we’ll take a closer look at two popular CPU air coolers: Deepcool AK620 and Dark Rock Pro 4.

Design and Dimensions
The Deepcool AK620 features a dual-tower “Chessboard” heat sink design with decorative boards on the heat sinks top, providing a unique appearance. It has a standing height of 160mm and a width of 138mm with both fans included, making it compatible with most ATX/ M-ATX cases. The pure copper bottom with six nickel plated heat pipes and aluminum fins maximizes heat dissipation, and the noise damping pads in fan corners keep noise levels under 28dB(A).
On the other hand, the Dark Rock Pro 4 has a sleek and minimalist design, with two virtually inaudible Silent Wings PWM fans and seven high-performance copper heat pipes. Its overall dimensions without mounting material are 5.7 x 5.35 x 6.40 inches, making it a little smaller than the AK620. The front fan has a funnel-shaped frame for high air pressure, and the cooling fins are airflow-optimized with cutouts to enhance RAM compatibility.
Compatibility
When it comes to compatibility, both the Deepcool AK620 and Dark Rock Pro 4 support a wide range of CPU sockets. The AK620 supports Intel LGA 2066/2011-v3/2011/1700/1200/1151/1150/1155 and AMD AM5/AM4, while the Dark Rock Pro 4 supports Intel 1700/1200/2066/1150/1151/1155/2011(-3) Square ILM and AMD AM5/AM4.
Performance
The Deepcool AK620 has a cooling capacity of up to 260W TDP, making it suitable for even overclocked CPUs in compact PCs. It comes with two high-speed DeepCool FK120 PWM 120mm fans with fluid dynamic bearings, each offering 1850RPM and 68.99CFM. The fans can be unclipped and adjusted higher if they’re blocking RAM slots.
The Dark Rock Pro 4, on the other hand, has a cooling capacity of 250W TDP, slightly less than the AK620. It comes with two virtually inaudible Silent Wings PWM fans, each offering a maximum rotational speed of 2500 RPM. The funnel-shaped frame of the front fan enhances high air pressure, and the overall design optimizes airflow for better cooling performance. The Dark Rock Pro 4 achieves only 24.3 dB(A) at maximum fan speed, making it one of the quietest CPU coolers available.
Price
The Deepcool AK620 is priced at around $60, while the Dark Rock Pro 4 costs around $90. The AK620 is more affordable, making it a good option for budget builds, while the Dark Rock Pro 4 is a high-end cooler with superior performance and quiet operation.
Conclusion – Which One to Choose?
Both the Deepcool AK620 and Dark Rock Pro 4 are excellent CPU air coolers with their unique features and benefits. The AK620 is more affordable, has a unique design, and offers excellent cooling performance, making it an excellent choice for budget builds. On the other hand, the Dark Rock Pro 4 is a high-end cooler with superior performance, quiet operation, and a sleek design, making it an excellent choice for high-end builds.
