DeepCool AK400 G2 (Single-Tower Air/4 Copper Heatpipes/220W TDP/120mm FDB Fan/Woodgrain or Digital Display) Review
The DeepCool AK400 G2 is a single-tower air cooler positioned as the smaller sibling to the dual-tower AK620, sharing the same design language and Core Touch heatpipe technology at a lower price and more compact footprint. It's available in two distinct aesthetic directions, one with woodgrain top covers reflecting the growing popularity of wood-accented PC builds, and one with a small digital display showing live system stats.

It's available in two distinct aesthetic directions, one with woodgrain top covers reflecting the growing popularity of wood-accented PC builds, and one with a small digital display showing live system stats.
Thermal Performance and TDP Rating
Rated for up to 220W TDP, this cooler covers mainstream systems comfortably and handles moderately demanding CPUs without issue, though as a single-tower design it sits meaningfully below the dual-tower AK620's headroom for the hottest or most heavily overclocked builds.
Fan Design and Noise
The single 120mm PWM fan tops out at 2200RPM and is rated at up to 31.45dB(A) under full load, and it can stop completely at very low PWM duty for silent idle operation. Independent testing notes this single fan actually runs up to 10% faster than either of the two fans on the dual-tower AK620 model, DeepCool's way of extracting comparable per-fan airflow from a lower total fan count.
Socket Compatibility and Installation
Coverage of current AMD AM4/AM5 and Intel LGA1851/1700/1200/115X platforms handles the overwhelming majority of current builds, with a straightforward five-step, all-metal mounting bracket installation process.
Design and Build
The matrix-pattern fin design carries over from the AK620, and the woodgrain top cover option taps into a genuine design trend that's grown in DIY PC building following cases like Fractal's North. DeepCool includes an alternate checkerboard black cover in the box for buyers who want to swap away from the woodgrain look without buying a separate cooler.
Comparison to Sibling Products
Against the DeepCool AK620, covered elsewhere on this site, this AK400 G2 trades that cooler's extra fan and two additional heatpipes for a smaller footprint and lower price, the sensible choice for a more mainstream or space-constrained build that doesn't need the AK620's extra headroom. Against the be quiet! Pure Rock, a similarly-priced 120mm single-tower competitor, independent comparative testing found the DeepCool design delivering stronger performance at a similar price point.
Who This Cooler Is Actually For
Mainstream builds that don't need dual-tower cooling capacity. 220W TDP support covers the majority of non-overclocked gaming and productivity builds.
Buyers who want the woodgrain aesthetic trend without committing to a full wood-themed motherboard. The included swap cover also keeps the option open to go conventional later.
Not for hot-running or heavily overclocked CPUs. The dual-tower AK620, covered elsewhere on this site, is the right step up for that need.
