Key Takeaways
- 1The AK620 G2 carried 242.5W in a noise-normalized test, so builders don’t have to choose between a quiet setup and a cool one.
- 2At 1386g, the AK620 G2 is 100g lighter than the original AK620, which is worth checking against your motherboard’s sag tolerance before mounting a dual-tower.
- 3The AK620 G2 Digital NYX runs $74.99, putting a display and lighter chassis into the same budget most builders already set aside for a plain dual-tower.
- 4RAM near the AK620 G2 averaged only 21.9C above ambient, so memory overclocks aren’t fighting extra heat soak from the cooler itself.
- 5The AK400 G2 Dark’s 120mm fan spins up to 2200 RPM, well past what most single-tower coolers ask of their fans, and it’s how the smaller unit kept pace with dual-tower designs.
- 6If the AK series is out of stock, the $50 Thermalright Royal Pretor 130 with dual 130mm fans undercuts most dual-tower coolers on price without giving up static pressure.
- 7Ryzen 9 9950X3D owners should plan on liquid, not air: builders running that chip are already moving to custom loops because its thermal output has outrun any air cooler on this list.
DeepCool AK620 G2: Design and Features
With both fans mounted, the AK620 G2 measures 127x144x159mm and weighs 1386g, 100g less than the original AK620. That’s a modest cut, but it matters for motherboards already carrying the sag of a dual-tower heatsink, and it comes without shrinking the footprint that does the actual cooling.
Enos Tech lists the AK620 G2 Digital NYX at $74.99 MSRP, a price that puts a display, a lighter chassis, and socket-agnostic mounting into a bracket most builders already budget for a plain dual-tower cooler.
At 159mm tall, the AK620 G2 clears the side panel of most PC cases without a second thought, a simplicity that liquid coolers don’t always offer once hose routing and radiator placement enter the picture.
Just a quick warning to any of your viewers thinking about getting a HAVN 420 VGPU case, you cant mount an RTX5070TI virtically if you install an Arctic Liquid Freezer III Pro 360, you need an AIO where the hoses dont come out of the bottom.
Thermal and Acoustic Results: A Dual-Tower That Leads the Pack
Tom’s Hardware ran the noise-normalized test, holding the cooler to a quiet fan profile rather than letting it run wide open, and it still carried away an average of 242.5W. That’s the number that matters for anyone who wants silence and performance rather than a choice between them: the AK620 G2 doesn’t need to be loud to move real heat.
The airflow off the tower isn’t just cooling the CPU either. RAM sitting near the heatsink averaged 21.9C above ambient room temperature, a modest enough climb that memory overclocks aren’t left fighting heat soak from a cooler that was supposed to be helping. That’s part of why builders are increasingly pairing the AK620 G2 with the highest core-count AM5 chips available, rather than reserving it for mid-range builds.

DeepCool AK400 G2 Dark Specifications and Results
The AK400 G2 Dark strips the dual-tower’s complexity down to a single tower fed by four 6mm copper heatpipes, a layout that’s been standard in this class for years precisely because it works. What sets it apart is the fan doing the pushing: a 120mm PWM unit rated to 2200 RPM, well above what most single-tower coolers ask their fans to do, which is how a smaller heatsink keeps pace with bigger ones.
| Heatpipes | Four 6mm copper |
| Fan Speed | Up to 2200 RPM |
| Noise Level | 41.9 dBA |
| Price (South Africa) | R487.00 |
That the AK400 G2 beat the dual-tower Sudokoo SK620V in thermal testing says more about the SK620V’s engineering than it does about single-tower coolers as a category, but it’s the kind of result that reopens a question builders keep asking anyway: with a modern flagship CPU and GPU pulling serious wattage, is air cooling still enough, or is it time to move to liquid?

Where to Buy If You’re Stuck: US Availability and Alternatives
Thermalright Royal Pretor 130
The stateside pick when the AK G2 line isn’t sitting on a shelfAt $50 USD the Royal Pretor 130 undercuts most dual-tower coolers on the market, and it does it while carrying a pair of 130mm fans rather than the 120mm units most competitors settle for. Bigger fan diameter means more air moved at a lower RPM for the same static pressure, which is the whole reason a shopper who can’t source a DeepCool unit shouldn’t treat this as a compromise pick.
Next-Gen Heat: What bLLC Cache Means for Razor Lake Thermals
Intel’s move to a bLLC cache layout on Razor Lake is a bet on feeding cores faster without spilling heat across a larger die area, but the flagship AMD part sitting in enthusiast builds right now already makes the case for what’s coming. Builders running the Ryzen 9 9950X3D are reaching for custom liquid loops rather than any air cooler, dual-tower or otherwise, because the chip’s thermal density has already outrun what a heatsink and a couple of fans can carry away. That gap between what a flagship demands and what a budget cooler can deliver is exactly what’s driving buyers toward secondhand and discounted parts instead of waiting on the newest silicon.
Waiting for the 5800X3D Anni to drop in price, bought my improved AIO cooler for it, but the 5800X3D Anni needs to be lower
