DeepCool AK620 DIGITAL review

The AK620 DIGITAL is a dual-tower air cooler with six 6mm copper heatpipes and two 120mm PWM fans. It adds a display that owners say shows either CPU temperature or load. It suits buyers who want a large air cooler for a recent Intel or AMD desktop and like a readout visible in the case.

APH Networks recorded a full-load temperature of 72°C. That was the best air-cooler result in its test, and two degrees behind a Thermaltake AIO. Owners also praise the cooling. Both points suggest it handles sustained loads well on a demanding chip.

There is a limit. Overclocking.com found the cooler failed to keep a Ryzen 9 7900X at 150W at decent temperatures at low revs. With a high power limit, expect to rely on higher fan speeds. A retailer lists a 260 W TDP, but DeepCool does not confirm that figure, so treat it with caution.

Noise is the weaker side of this cooler. DeepCool quotes 28 dBA at full load. Independent figures are far higher. Tom's Hardware measured 43.4 dBA under load with an i7-13700K and no power limits. Tech4Gamers measured 53 dB(A) with its own meter. Both sit well above the manufacturer's claim, and owners report fan noise under load.

The two fans run from 500 to 1850 RPM and use fluid dynamic bearings. That range leaves room to adjust the fan curve, which is what Tech4Gamers suggests. If you are sensitive to noise, plan to do that rather than leave the fans on default behaviour.

Socket support is broad. DeepCool lists Intel LGA2066, 2011-v3, 2011, 1851, 1700, 1200, 1151, 1150 and 1155, plus AMD AM5 and AM4. Current platforms are covered, and so are several older ones.

Height needs checking. The cooler stands 162 mm overall, with the heatsink alone at 157 mm. Because of that, a compact case may not take it, so compare the figure against your case's stated CPU cooler limit.

RAM clearance is 43 mm maximum according to LDLC. Tech4Gamers says the adjustable front fan accommodates RAM up to 47 mm. With tall memory modules, the position of that front fan decides whether they fit.

The cooler is a dual-tower design with six 6mm copper heatpipes and two PWM fans. The fans use fluid dynamic bearings. DeepCool backs the cooler with a three-year limited warranty. The front fan can be adjusted to clear memory, which helps when RAM height is a concern.

Owner feedback on the display is lukewarm. It is limited to CPU temperature or load. If you want a screen that shows more, it will not do that. If you only want a quick glance at how hot the CPU is, it covers the basics.

This is a good match for someone building a fast mainstream or high-end desktop who wants air cooling that APH Networks found close to an AIO. It is less suited to a quiet-first build or to a chip held at a high power limit with the fans kept slow. Check case height and RAM height before buying, and expect to spend a little time on the fan curve.
