The Deepcool AK620 is a high-performance CPU cooler designed for gamers and PC enthusiasts. Its dual-tower design and high-quality fans aim to deliver excellent cooling performance while maintaining low noise levels. In this review, we focus on its noise levels during heavy load testing to assess its suitability for quiet computing environments.

Overview of the Deepcool AK620

The AK620 features a dual-tower heatsink with six heat pipes, providing efficient heat dissipation. It comes with two 120mm PWM fans that can operate at various speeds depending on the thermal demands. Its installation process is straightforward, compatible with most modern CPUs, including Intel and AMD sockets.

Testing Methodology

To evaluate noise levels, we installed the AK620 in a test system equipped with a high-performance CPU. We used a decibel meter placed at a standard distance of 30 cm from the cooler. The testing involved running Prime95 stress tests for one hour to simulate heavy load conditions. Noise levels were recorded at idle, moderate load, and maximum load.

Noise Levels During Heavy Load

During the heavy load test, the AK620's fans reached their maximum speed, approximately 2000 RPM. The recorded noise level was around 45 decibels (dB). This level is considered acceptable for most users, especially given the intense thermal workload. Compared to other high-end coolers, the AK620 maintains a relatively quiet operation under stress.

Comparison with Similar Coolers

  • Noctua NH-U12S: 40-42 dB under similar conditions
  • Corsair iCUE H150i: 48-50 dB at maximum speed
  • Be Quiet! Dark Rock Pro 4: 38-40 dB

The AK620's noise level is comparable to other high-performance air coolers and quieter than many liquid cooling solutions at maximum load. Its fans are well-balanced, providing effective cooling without excessive noise.

Additional Observations

Users have reported that the AK620 remains relatively quiet during everyday tasks and gaming, with noise levels barely noticeable at moderate speeds. The dual-fan setup helps distribute airflow evenly, reducing noise caused by turbulence. The cooler's design also minimizes vibrations, contributing to quieter operation.

Conclusion

The Deepcool AK620 offers excellent cooling performance with a noise level of around 45 dB during heavy load testing. Its quiet operation makes it suitable for users seeking high performance without sacrificing silence. Overall, the AK620 is a competitive choice among air coolers, balancing efficiency and noise control effectively.
