  • Real-time CPU temperature and usage shown on top digital display with high-temp alert
  • 220 W TDP cooling via four 6 mm heat pipes with converging centre design
  • PWM fan adjusts 500–1850 RPM for up to 68.99 CFM airflow at ≤28 dB(A)
  • Fluid Dynamic Bearing ensures quiet, long-life operation across the full speed range
  • Fits Intel LGA 1700/1200/1151/1150/1155 and AMD AM5/AM4 sockets

Digital Display Monitoring

The AJI AK400 Digital CPU Cooler features a top-mounted visual display that shows real-time CPU temperature and usage data. It connects via a motherboard USB 2.0 9-pin header to read accurate system information and includes a high-temperature reminder function for added awareness during heavy workloads.

220W TDP Heat Dissipation

Four 6mm heat pipes with a converging centre design increase the contact area on the CPU core for improved thermal conductivity. The FK120 fan operates between 500 and 1850 RPM, delivering up to 68.99 CFM airflow and 2.19 mmAq static pressure while maintaining noise at or below 28 dB(A) under PWM control.

Broad Socket Compatibility

The cooler supports Intel LGA1700, 1200, 1151, 1150 and 1155 sockets as well as AMD AM5 and AM4 platforms. Its 120mm fan dimensions and four heat-pipe layout fit standard tower configurations, though builders with compact cases or tall memory modules should verify clearance independently.

Questions about this item

Will the AK400 Digital fit on my existing LGA1200 motherboard without blocking RAM slots?

The cooler supports Intel LGA1200 among other sockets; its 120 mm fan and four 6 mm heat pipes are designed for standard clearance, but RAM height compatibility depends on your specific module dimensions.

How do I verify the digital display is reading CPU temperature correctly after installation?

Connect the USB 2.0 9-pin header to the motherboard, then check that the top display shows live CPU temperature and usage; a high-temperature reminder will trigger if thresholds are exceeded.

Does the box include the USB 2.0 9-pin cable needed for the display, or must I buy it separately?

The supplied cooler includes the FK120 PWM fan with FDB bearing, four heat pipes, mounting hardware for Intel LGA1700/1200/1151/1150/1155 and AMD AM5/AM4, and the USB 2.0 9-pin connector for the digital display.
