DeepCool AK400 Digital Pro Black CPU Air Cooler - ARGB
The DeepCool AK400 Digital Pro is an air cooler for Intel and AMD mainstream processors that combines performance cooling with a real-time display showing temperature, CPU usage, and power draw simultaneously. It features upgraded CTT 2.0 heatpipes, a single optimized FT12 SE fan with fluid dynamic bearing, and a color-coded temperature warning system that changes from green to orange to red as heat rises.
Why this product
Multi-data display with live CPU metrics
The integrated screen shows temperature, usage percentage, and wattage all at once, controlled via DeepCool software over a USB 2.0 header.
Color-coded temperature warnings at a glance
The display indicator turns green below 80 °C, orange between 80–90 °C, and red above 90 °C, so you see thermal status instantly without checking software.
CTT 2.0 heatpipe technology for direct contact cooling
Optimized copper heatpipes with improved layout make direct contact with the CPU IHS, delivering better thermal transfer than the previous generation.
Balanced airflow and noise in one fan
The FT12 SE PWM fan runs 500–1750 RPM, moves 60.89 CFM, and stays at or below 25 dB(A) thanks to its fluid dynamic bearing and optimized blade profile.
Subtle ARGB accent lighting
Two top panel edges have understated ARGB strips that sync to compatible motherboard headers for coordinated RGB builds without overwhelming visuals.

- Fan Size120 mm
- Fan Speed Range500–1750 RPM
- Noise Level≤25 dB(A)
- DisplayMulti-data point ARGB screen with temperature, usage, and wattage
- Heatpipe TechnologyCTT 2.0 with four copper heatpipes
- SKUDEE-853
- EAN6933412728832
- Works with Intel LGA1851, LGA1700, LGA1200, LGA1150, LGA1151, and LGA1155 processors.
- Works with AMD AM5 and AM4 socket processors.
- Compatible with standard 120 mm case fan mounts and most mid-tower and larger cases.
- Requires an open USB 2.0 header on the motherboard to control the display and show live metrics; cooling function works without it, but the screen will not operate.
- Display information may experience minor delays depending on hardware configuration, polling periods, and system settings.
Best for
- Builders who want to monitor CPU temperature, usage, and power draw without opening monitoring software
- Systems where quiet operation matters; the single FT12 SE fan stays under 25 dB(A) across its range
- Intel and AMD users on mainstream platforms seeking mid-range air cooling with modern display features
- Enthusiasts building RGB-synced systems who prefer understated lighting over dominant ARGB coolers
Trade-offs
- High-end overclocking. A single 120 mm fan cooler is not designed for extreme or sustained CPU overclocking loads.
- Systems with no USB 2.0 header. The display requires a USB 2.0 header to function; cooling still works, but the screen will not turn on.
- Compact cases with severe space constraints. The tower design is taller than low-profile coolers and may not fit mini-ITX or very small form-factor builds.
- Passive or fanless cooling setups. This cooler requires active fan operation and cannot run passively.
The AK DIGITAL air coolers have gone pro with their newest iteration. The AK400 DIGITAL PRO has been upgraded in many aspects, including a multi-data point screen, visual color temperature warnings, and CTT 2.0 heatpipe technology. A very worthy step up in not just aesthetics but cooling performance.
The sleek and shiny screen of the AK400 DIGITAL PRO has been enhanced to show more than just the temperature; usage and wattage have been added and are displayed at the same time. The display is controlled via DeepCool software and only requires an open USB 2.0 header.
*Due to variances in hardware configurations, polling periods, and system settings, the displayed information may experience minor delays.
*CPU temperature based on Intel: CPU Package / AMD: CPU Tdie
The temperature warning alert system has also been upgraded to have a color-coded visual indicator: under 80 °C, the indicator will stay green; between 80 and 90°C, it will be a bright orange; when things get warm above 90°C, it will turn red.
An all-black variation of the dominant AK400 high-performance CPU cooler. The same premium-quality materials, featuring four advanced copper heat pipes, a dense matrix pattern tower heat sink, and a silent FDB fan, produce a powerful winning formula for high performance cooling in a ZERO DARK raven design.
Upgraded to the newly designed FT12 SE fans with a true fluid dynamic bearing, the AK PRO models will get a PWM fan with a blade profile that has been optimized for the perfect balance of airflow and static pressure while minimizing the fan acoustics.
Subtle ARGB strips at two of the top panel edges add an understated glow that can be easily synced to compatible ARGB headers of your motherboard.
An upgrade to DeepCool's newest Core Touch Technology 2.0 dramatically improves direct-touch heatpipe coldplates. The heatpipes have been optimized and laid out to promote the best possible thermal transfer directly from the CPU IHS. As a result, CTT 2.0 provides a bump in cooling performance.
The durable mounting hardware provides a simple installation process that ensures proper contact and equal pressure on mainstream Intel and AMD platforms.
