DeepCool AK400

7.1/10verdict: good, not the best

The DeepCool AK400 is for builders who want a low-cost air cooler for a mainstream Intel or AMD desktop CPU. It suits anyone who wants current socket support, including LGA1851 and AM5, without paying for a bigger tower or an AIO. It is a sensible pick for mid-range builds, and less so for chips that draw well above its 220 W rating.

6.9/10verdict: good, not the best

The AK620 DIGITAL is for builders who want a large dual-tower air cooler for a current Intel or AMD desktop. It suits anyone who values strong cooling and a visible temperature or load readout in the case. It is best for people willing to set a custom fan curve to manage noise.

Strengths and weaknesses

DeepCool AK400

  • + Strong cooling for the money, per owners
  • + Supports LGA1851, LGA1700, AM5 and AM4
  • + Easy installation reported by owners
  • − Reported 8% throttling on an 11900K in the FPU test
  • − 42 dBA at full 1850 RPM in KitGuru's figures
  • − Mounting kit and pre-applied paste draw criticism

Skip it if:

  • Buyers with a hot, high-power CPU that sits near or above 220 W under sustained load
  • Anyone with a compact case that can't take a 155 mm cooler
  • Buyers who want quiet full-speed operation without setting a fan curve

DeepCool AK620 DIGITAL

  • + Best air-cooler result in APH Networks' test
  • + Wide socket support including LGA1851, LGA1700 and AM5
  • + Three-year limited warranty
  • − Reviewers measured 43.4 to 53 dBA under load
  • − Struggled with a 150W Ryzen 9 7900X at low revs
  • − Display shows only CPU temperature or load

Skip it if:

  • Buyers building a very quiet system who will not tune fan curves
  • Anyone with a compact case that cannot fit a 162 mm cooler
  • People who want a display showing more than CPU temperature or load
