Features Overview
Triple Chamber Design
The CORSAIR AIR 5400 LX-R features an innovative triple-chamber design that isolates heat-generating components. This separation ensures optimal cooling for the CPU, GPU, and PSU, preventing thermal interference and simplifying cable management.

Optimized Airflow
Specialized dual airflow conduits in the main chamber draw cool air from outside the chassis and direct it efficiently towards the graphics card. This vertical airflow design ensures thorough cooling of all components and effective exhaust of hot air.

Dedicated AIO Radiator Chamber
The front of the chassis features a dedicated chamber for a 360mm All-In-One (AIO) liquid cooler. This design ensures that heat generated by CPU cooling is kept separate from other components, enhancing overall thermal performance.

Setup
1. Pre-Installation Checks
Before starting assembly, ensure you have all necessary components and tools. Unpack the case carefully and remove any protective films or packaging materials.
2. Motherboard Installation
- Open the side panels by gently pulling them outwards from the integrated hinges.
- Install the necessary motherboard standoffs for your motherboard form factor (Mini-ITX, Micro-ATX, ATX, E-ATX).
- Carefully place your motherboard into the chassis, aligning it with the standoffs and I/O shield opening.
- Secure the motherboard with the provided screws. If using an inverted connection motherboard, ensure proper alignment with the rear cable cutouts.
3. Power Supply Unit (PSU) Installation
- Locate the dedicated PSU chamber at the rear of the case.
- Slide your ATX power supply into its designated slot.
- Secure the PSU with screws from the rear of the chassis.
4. Storage Device Installation
The case supports various storage configurations. Install your SSDs and HDDs into the designated drive bays in the third chamber, securing them with the provided hardware.
5. Graphics Card (GPU) Installation
- Remove the necessary PCIe slot covers.
- Insert your graphics card into the primary PCIe slot on the motherboard.
- Secure the GPU with the retention mechanism or screws.
- Adjust the integrated anti-sag GPU support bracket to provide stability for your graphics card.
6. Cooling System Installation (AIO/Additional Fans)
If installing an AIO liquid cooler, mount the radiator and fans in the dedicated front chamber. For additional fans, utilize the top, bottom, or rear mounting points as desired. Ensure fans are oriented for optimal airflow (intake or exhaust).
7. Cable Management
Utilize the RapidRoute 2.0 system with its pegboard tray and adjustable cable ties to route all power and data cables neatly behind the motherboard tray. This ensures unobstructed airflow and a clean interior aesthetic.
8. Connecting Front I/O
Connect the front panel cables (USB, audio, power button) to their respective headers on your motherboard. Refer to your motherboard manual for specific header locations.
Operating
Powering On
