Smart Controls That Matter

The H400i's unique Smart Device includes features from our HUE+ and GRID+ V3 digital controllers, allowing for effortless control of RGB lighting and fans through CAM software. Customized lighting is streamlined with two integrated and individually addressable RGB LED strips. Don't waste time checking compatibility, installing, or manipulating physical buttons; our out-of-the box, elegantly controlled CAM software is all you need.

Beautiful Craftsmanship

The H400i is available in four color combinations to match your taste, and its elegant all-steel construction is shared across all sizes in the new H-series. The tempered glass panel and signature PSU shroud showcase beautiful builds.

Compact Size

Measuring in at 393mm (without feet) high and 421mm long, the H400i bucks the trend of tall, thick cases, enabling you to keep your PC's footprint to a minimum.

Enjoyable Builds For All

Cable management can often take more time than assembly. We designed a new cable routing kit with pre-installed channels and straps, on the back of the motherboard tray, for intuitive and easy wiring. We also upgraded our signature cable bar to be adjustable. The H400i layout ensures you'll enjoy building your PC as much as you enjoy gaming on it.

Streamlined Cooling

We simplified water-cooling installation: a front drop-in bracket is designed for radiators up to 280mm, and integrated reservoir mounting for custom-loop systems. Three Aer F 120mm fans* are included for optimal internal airflow. To preserve your system's clean looks, front and PSU intakes are fully filtered.

* Case version fans and specs vary from retail version.

Modern Storage

Storage installation is a snap with the single, quick-release 2.5" SSD tray positioned on the PSU shroud. There are also two steel trays behind the motherboard with an additional 3.5" mounting below the shroud. This storage layout optimizes airflow and interior space for a clean-looking build.

Adaptive Noise Reduction

Our unique Adaptive Noise Reduction uses an on-board noise sensor to measure and learn the specifics of your system to find the ideal balance between fan speed and cooling. With up to a 40% reduction in fan noise level, you won't need to waste time designing custom fan curves. Leveraging machine learning to improve its results, this will ensure your fan settings are always optimal, even if you change hardware.

System Requirements

  • PC with open internal USB 2.0 port and Windows® 10 operating system recommended. Internet connection is needed to download CAM.
  • Some CAM features require Internet access, a valid email address and acceptance of our current Terms of Service.
