Corsair has been talking about the new Air 5400 for many months and we are truly excited the time has come for a review. The reason we are so excited is that Air 5400 is a triple-chamber design, so the motherboard and graphics card live in the main chamber, the power supply, cables and storage are housed in the second chamber and the AIO cooler gets a chamber all to itself. Does it work? Heck yes, it works!

Main features (from Corsair's review guide)
- Triple-Chamber Design – To improve component cooling performance, we’ve isolated CPU cooling from GPU cooling so they both have access to separate sources of fresh air from outside the case, and that neither component can heat up the other. A front-mounted 360mm AIO (sold separately) pulls in fresh air from outside the case, while the GPU is cooled by the included reverse-rotor fans below it, which draw air from outside the case. The third chamber is behind the motherboard for storage devices, a power supply, and excess cables.
- Dual Airflow Ducts – The main chamber features built-in airflow ducts in the bottom and top of the chassis to help air move vertically through the main chamber for constant upwards airflow. The included bottom-mounted fans pull fresh air in from outside the case and channel it directly into the GPU above. As the air gets warmer it naturally rises and exits through the duct at the top of the case, and there’s 3x 120mm fan mounts in this location to assist with air movement as well. A 120mm fan can be mounted for rear exhaust via two “arms” in the accessory box but our testing shows most users won’t need a fan in this location, but it’s available to those who want it.
- Included Reverse-Rotor Fans – Reverse-rotor fans are included with the Air 5400 with 3x 120mm ARGB fans pre-installed in the bottom of the case to pull air in from outside the chassis and exhaust it up into the GPU. Fan options include PWM ARGB RS-R fans for those who prefer motherboard fan control or iCUE Link LX-R fans for those who want to experience the simplicity of iCUE Link single-cable connectivity (System Hub included). Both fan options provide an unobstructed view of the RGB lighting due to their reverse-rotor design while still providing powerful, quiet airflow.
- French Door Glass Side Panels – The exterior of the case features two glass panels that wrap around three sides of the case (front, side, rear) and open outwards from the corner, providing a panoramic view of your hardware and easy access to the case internals.
- Rapid-route 2.0 – The Air 5400 features Corsair’s second-generation cable management technology known as RapidRoute. This new version’s innovation is a pegboard motherboard tray with movable and modular ratcheting cable tie blocks. These blocks can be moved to any location, rotated, and expanded laterally to make cable management easier since you’re not constrained by fixed cable tie locations.
- Nylon Brush Chamber Dividers – We’ve replaced plastic grommets between the chambers for cable routing with nylon brushes for a cleaner look and more flexibility when managing cables between the chambers.
- CPU Cooling Exhaust Opening – One of the most distinguishing features of the AIR 5400 is the large opening on the right side of the case, which allows hot air coming out of an all-in-one liquid cooler to be exhausted immediately away from the case, as the wide opening and moulded ducts allow warm air to be quickly guided away from the chassis and nearby components.
- USB Type-C Top-Mounted I/O – The AIR 5400 has fully modern top-mounted I/O with three USB Type-C ports. The cable from the case connects to the USB 3.0 port on the motherboard, which splits off into two ports via a mux chip to dual USB 5Gb/s ports, and the high-speed USB Type-C connector powers the lone USB Type-C 20Gb/s for high-speed data transfers.

Testing
To put this case through its cooling paces we will be using a test system consisting of an AMD Ryzen 7 9800X3D, Palit RTX 5080 and an SSD. This system allows us to produce a substantial amount of heat and effectively test the Corsair Air 5400‘s cooling capabilities.
Test System:
- Processor: AMD Ryzen 7 9800X3D
- CPU Cooler: Corsair iCUE Link Titan 360 RX LCD
- Motherboard: MSI MAG Tomahawk X870E WiFi PZ
- Memory: 48GB Corsair Vengeance RGB DDR5-8400
- Graphics card: Palit GeForce RTX 5080 OC 16GB
- Power supply: Corsair HX1000i Shift with Premium Cable Kit
- SSD: 2TB Corsair MP600 Elite
- OS: Windows 11
Cooling Performance

Cooling Performance Overview
Under load our CPU was drawing 129W and the graphics card 325W so this was a stiff test for the Air 5400. While an ultra-high end gaming PC might double those figures, we are confident our findings would apply to across the board. Once we moved the AIO cooler from the roof of the case to its correct location in the third chamber, we found the cooling of the Air 5400 was excellent. The case performed well with the three stock fans in the floor and there was no benefit adding more fans in the roof or the rear of the case.
Closing Thoughts
When we first saw the Corsair Air 5400 at Computex we had to wonder whether the triple-chamber design was a gimmick.
We have been clear for some time that it makes sense to separate the CPU cooler from the graphics card, and the approach taken by the Air 5400 is one of the best we have seen. What we particularly like is the simplicity of devoting the main chamber to the huge, expensive and power-hungry graphics card and removing the other hardware from the equation.

We helped the cause by using a Project Zero motherboard from MSI that kept most of the cables in the second compartment along with the power supply. This led to a clear separation between the graphics card and the CPU cooler and also added some visual impact to our finished PC. The downsides to the Air 5400 are clear as it is large, heavy and expensive but it is also very effective and delivers on Corsair's promises.
The Corsair Air 5400 LX-R has an MSRP of £284.99/$329.99.
Pros:
- Novel triple chamber design with excellent CPU cooling.
- The finished PC looks ultra-tidy.
- Front panel I/O has three USB-C and no USB Type-A.
- Cable grommets have been replaced with brush dividers.
Cons:
- Installing a cooler in the third compartment is fiddly.
- High price.
- The storage drive mount looks like an afterthought.
- Front panel I/O has three USB-C and no USB Type-A.
KitGuru says: Corsair Air 5400 is novel, effective and rather expensive.
