Design, Build and Connectivity
The AK620 G2 Digital NYX features a dual-tower design with two 120 mm fans for a balance between cooling and acoustic performance – or just sheer cooling performance. It also comes with glossy top covers that doubles as a protection to the digital display. Compared to the original AK620, this dual cover design allows easier installation.
The AK620 G2 keeps things cool with six heat pipes that pull heat straight from a precision-milled cold plate. The contact surface is made from CNC-machined aluminum, while the rest of the cooler sports a black coating, likely powder-coated for extra corrosion resistance. The front tower features a cutout to ensure universal RAM clearance.
The AK620 G2 includes two 120 mm fans, each featuring 7 blades and built-in rubber dampeners to reduce vibration. These fans can spin at speeds of up to 2000 RPM, and DeepCool notes that they can operate at just 5% PWM, which is impressively low. On that note, the fans are able to operate at 0 RPM mode and could cleans itself via its Activate Clearing Tech (ACT), preventing dust build-up.
The AK620 G2 Digital NYX includes a Y-splitter for the fans and a USB 2.0 header for the digital display. If the fans are connected using the splitter, the USB header is necessary; otherwise, they’ll run at a constant speed of about 2000 RPM.
Installation and Clearance
Installing the AK620 G2 is pretty straightforward, especially for AMD users, since it makes use of the stock AM4/AM5 backplate. It also features an adjustable mounting bracket, letting you offset the cold plate for improved contact and potentially better performance on any supported platform.
While installation is easy, cable management isn’t quite as smooth. This is a recurring theme with DeepCool products, with the CH160 PLUS being a prime example. Still, it’s nothing a bit of elbow grease and a few zip-ties can’t fix.
Software
The AK620 G2 Digital Nyx works seamlessly with DeepCool’s DeepCreative software. Once installed, you’re welcomed by a clean, straightforward interface where you can choose to enable temperature alerts, let the motherboard manage the fans instead of the software, or tweak the fan modes to your liking.
The display panel is big enough to show the key sensor data you need. While the sensor data isn’t replaceable and the brightness adjustment is nowhere to be found, I wouldn’t dock points from the AK620 G2 for these minor drawbacks.
Temperature
The AK620 G2 Digital NYX handled cooling the AMD Ryzen 9 7900X well at 65 W and 105 W, delivering good results across different fan speeds. But on the 170 W profile, it couldn’t keep the CPU from reaching its 95 °C thermal cap. For reference, the AMD Precision Boost 170 W profile actually draws at least 216 W of power when it reached the thermal cap in our test.
Noise
The AK620 G2 stands out for its impressively quiet performance, even when the fans are running at full speed. In my tests, the sweet spot was at 50% PWM (around 1146 RPM), offering great cooling power without any noticeable or distracting noise.
| Sound Level Meter | Noise | ||
|---|---|---|
| PWM (%) | Noise (dBA) | Speed (RPM) |
| 25 | 32.1 | 720 |
| 50 | 33.5 | 1146 |
| 75 | 36 | 1580 |
| 100 | 40.4 | 1988 |
Final Thoughts
The DeepCool AK620 G2 Digital NYX is a well-rounded evolution of one of the most popular air coolers in the market. It carries forward everything that made the original AK620 a crowd favorite: the dual-tower design, six heat pipes, and solid build quality, while layering on meaningful upgrades like the quad-segmented digital display, the adjustable offset cold plate, and DeepCreative software integration.
For mid-range builds or systems running CPUs within the 65 W to 105 W range, it performs admirably and stays impressively quiet doing so. However, for those pairing it with high-TDP chips like the Ryzen 9 7900X pushed to its 170 W profile should temper their expectations, as it struggles to keep temperatures in check at that power draw.
If your workloads stay within more typical bounds, the AK620 G2 Digital NYX is an easy recommendation. It looks great, runs quietly, and offers a level of real-time insight rarely seen at this price point.
