The Antec Flux Pro Noctua Edition is the latest collaboration between two industry titans, combining the expansive airflow of the Antec Flux Pro chassis with the world-class acoustic and cooling engineering of Noctua. This isn’t the first time we’ve seen Noctua team up either, with them having a range of graphics cards and power supplies on the market thanks to their work with ASUS and Seasonic, and as I’m writing this review, I saw that they’ve paired up with Asetek for a generation of Noctua coolers too. But while these have been nothing short of exceptional products, they’re designed for PC enthusiasts and gamers who refuse to compromise between thermal headroom and silence, and this comes at a premium price, as you might expect.

This full-tower case aims to provide a premium foundation for the most demanding modern hardware, such as flagship graphics cards and processors, but by integrating Noctua’s latest G2 series fans and a bespoke Noctua flavoured colour scheme, aka brown, it aims to ensure you can get the best hardware, while also keeping it cooler and quieter.

Premium Cooling and Design

A primary focus of this chassis is the integration of six premium Noctua G2 fans, which provide a significant upgrade over standard case fans in terms of both static pressure and noise efficiency, and if you’re a Noctua enthusiast like myself, aesthetics too; I do love their brown theme, I don’t know why, I don’t need to justify myself, but I just do, and I’m not alone in that.

The cooling layout of the Flux Pro is optimised using a mix of 140mm and 120mm fans to ensure consistent airflow across critical components like the processor and graphics card. Beyond the fans, the case features a unique aesthetic that includes FSC-certified walnut wood trim on the front panel and the signature Noctua brown colourway on the grommets and panels. For ease of use, the inclusion of the superb NA-FH1 fan hub allows for synchronised control of the entire cooling configuration via a single motherboard header, while the iUnity display on the side panel provides real-time monitoring of component temperatures. Overall, that’s a lot of premium hardware in one case, and well, that’s why it currently costs £399.99.

Key Features

Six pre-installed Noctua G2 series fans (4x NF-A14x25 and 2x NF-A12x25)
Integrated NA-FH1 eight-channel PWM fan hub
FSC-certified walnut wood front panel accents
Built-in CPU and GPU temperature display with iUnity software support
Tool-free side panels and top cooling bracket for easy access
Innovative iShift 90-degree rotatable PSU mount for improved cable routing
Signature Noctua colour scheme with brown silicone grommets and accents
Full-size pull-out bottom dust filter for simplified maintenance

The technical specifications of the Flux Pro Noctua Edition are suitably impressive. It supports motherboards up to E-ATX in size and provides massive clearance for graphics cards up to 455mm in length, making it suitable for even the largest cards currently available; such as the ASUS Noctua editions, of course. Water cooling support is equally impressive, with the ability to house 420mm radiators in both the front and top positions. Storage is handled via a modular system that can accommodate up to ten drives, ensuring plenty of space for high-capacity builds; so basically, all the best stuff money can buy for a PC enthusiast.

The cooling performance is driven by a specific combination of Noctua’s high-performance fans, which have been selected to balance intake volume with exhaust. The front intake utilizes three 140mm G2 fans to pull in massive amounts of fresh air, while a fourth 140mm unit at the rear and two 120mm units on the PSU shroud ensure that air is moved towards the GPU and CPU, and moved away again just as efficiently.
