Corsair iCUE 4000D RGB Airflow: White Mid-Tower Case, 3x AF120 RGB Fans

The Corsair iCUE 4000D RGB Airflow in True White is a mid-tower case designed to balance strong thermal performance with eye-catching RGB lighting right out of the box. The high-airflow front panel is engineered to allow maximum air intake, while the three included AF120 RGB Elite PWM fans — each rated at up to 2,100 RPM and 65.57 CFM — use Corsair's AirGuide technology to focus airflow and increase static pressure for more effective cooling. The included iCUE Lighting Node PRO gives builders full control over the RGB lighting through Corsair's iCUE software, enabling synchronization with other Corsair peripherals and components without needing additional controllers.

Inside, the 4000D RGB Airflow provides a spacious layout that accommodates ATX motherboards, graphics cards up to 360mm long, and extensive cooling configurations — including a 360mm radiator in the front and a 280mm radiator in the roof (clearance permitting based on RAM height). Two additional 120mm fan mounts on the PSU shroud offer an uncommon feature: the ability to install fans for direct airflow to the GPU, which can meaningfully reduce graphics card temperatures under load. The bottom-mounted PSU compartment with a full-length shroud keeps the power supply and excess cabling hidden for a clean build aesthetic. Modern front panel I/O with USB 3.2 Gen 2 Type-C rounds out a case that is well suited for mid-range to high-end gaming and workstation builds alike.
