Deepcool AK620 CPU Cooler Review


The Deepcool AK620 is a high-performance air CPU cooler that was released in 2022. With its large heatsink design and dual tower fans, it aims to deliver exceptional cooling performance while keeping noise levels relatively low. In this Deepcool AK620 review, we’ll take a close look at the features, installation process, performance benchmarks, pros and cons of this cooler to help you decide if it’s the right choice for your build.

Overview and Features

The Deepcool AK620 features a dual tower heatsink design with six 6mm heatpipes that make direct contact with the CPU for effective heat dissipation. The heatsink has densely packed aluminum fins with wave-curved edges to maximize surface area.

For cooling, it comes with two 120mm PWM fans that can operate between 500 to 1800 RPM. The fans have fluid dynamic bearings for quiet and reliable operation. The fan hub allows PWM fan speed control to balance cooling performance and noise.

The AK620 has support for most modern CPU sockets including Intel LGA1700, LGA1200, LGA1151, LGA2066 and AMD AM4, AM5. With dimensions of 134.8 x 131 x 163mm and weighing 1.56kg, the large heatsink offers TDP support up to 230W, making it suitable for overclocked processors.


Installing the Deepcool AK620 is straightforward with the tool-free mounting system. For Intel CPUs, you attach the backplate first and then install the four push pins through the motherboard holes. The plastic bracket then locks the heatsink securely in place.

For AMD, the stock backplate is used. The plastic bracket has cutouts that align with the AMD backplate. After applying the thermal paste on the CPU, you place the heatsink on top and secure it similarly with the push pins.

Overall, the entire installation process is hassle-free and can be completed within 10 minutes. The detailed manual provides clear instructions too.

When it comes to cooling performance, the Deepcool AK620 delivers excellent results, outperforming many 240mm liquid coolers. In tests, it was able to keep the Intel Core i9-12900K at around 75°C under full load overclocked to 5.2Ghz all-cores. This is impressive cooling considering the 250W power draw of the overclocked i9-12900K.

With a Ryzen 9 5950X overclocked to 4.6Ghz, temperatures remained below 83°C in a 20-minute stress test. So the AK620 has no issues taming the heat from either top-tier AMD or Intel CPUs.

The dual tower design and six heatpipes effectively dissipate heat away from the processor. And the 120mm fans can ramp up to provide tremendous airflow when needed. At the same time, the noise levels stay relatively low at around 30 dBA when running at normal speeds.

Overall, the cooling performance rivals and even exceeds many premium air coolers and 240/280mm AIOs. The AK620 punches well above its weight class and price bracket when it comes to thermal performance.


  • Superb cooling performance for the price
  • Big dual tower heatsink with 6 heatpipes
  • Quiet 120mm PWM fans effective at both low and high speeds
  • Secured firmly with tool-free mounting
  • Compatible with modern Intel and AMD sockets
  • Excellent value for money


  • Large and heavy unit
  • No RGB lighting


With its large heatsink, heatpipe direct contact design, and dual 120mm fans, the Deepcool AK620 delivers excellent cooling performance that can handle overclocked high-end CPUs like the Core i9-12900K and Ryzen 9 5950X. It keeps noise levels relatively low and comes at an affordable price.

If you want liquid cooling-level thermal performance on air cooling for around $60-70, the AK620 is easily one of the best choices available. The only downside is the bulky size, but that’s expected for this level of cooling capacity. Overall, the Deepcool AK620 earns a strong recommendation as a high-value air cooler that can cool premium processors without breaking the bank.
