The Antec Flux Pro Noctua Edition is a full-tower case whose main upgrade over the standard Flux Pro is a complete Noctua cooling package: six premium PWM fans, an NA-FH1 hub and brown Noctua styling. It is designed for large, high-airflow systems, with room for E-ATX boards up to 285 mm wide, graphics cards up to 455 mm and CPU coolers up to 190 mm. Noctua claims the edition matches the original Flux Pro’s ventilation while running up to 8 dB(A) quieter, but that figure is a manufacturer comparison rather than an independent whole-PC measurement.
What the Noctua Edition changes
Antec and Noctua announced the case on March 17, 2026. The chassis is based on the Flux Pro, while the bundled fans and brown color scheme distinguish this edition. Noctua CEO Roland Mossig said, “The Flux Pro has been rightfully praised for its exceptional quiet cooling potential, so it was an obvious candidate for the project.” The announcement is documented by Noctua.

Included cooling hardware
- Three 140 mm NF-A14x25 G2 PWM fans as front intakes
- Two 120 mm NF-A12x25 G2 PWM fans mounted on the PSU shroud
- One 140 mm NF-A14x25 G2 PWM rear exhaust
- One NA-FH1 PWM fan hub
That is a six-fan package rather than an empty or minimally populated chassis. The hub simplifies connecting the included fans to a motherboard header, although builders should still verify header current limits and their preferred fan-control layout.
Size and component compatibility
Noctua lists dimensions of 245 × 545 × 530 mm and a fan-equipped weight of 13.75 kg on its specifications page. Measure the intended desk, floor space and doorway route before buying; this is a substantial full tower.

| Component or feature | Published support | Planning note |
|---|---|---|
| Motherboards | Mini-ITX, microATX, ATX and E-ATX | Antec specifies E-ATX boards up to 285 mm wide; check the exact board against cable-routing and tray clearances. |
| CPU cooler | Up to 190 mm high | Compare the cooler’s published height, including fan clips or top covers, with the case limit. |
| Graphics card | Up to 455 mm long | Radiators, front fans and GPU power connectors can reduce usable space in a particular layout. |
| Radiator support | Front and top up to 420 mm; PSU cover up to 360 mm; bottom up to 240 mm; rear 120 or 140 mm | Check radiator thickness, fan thickness, RAM height, motherboard heatsinks and GPU position together. |
The published limits come from Noctua’s specifications and Antec’s product page. Maximum figures are not a guarantee that every combination will fit without interference.
How credible is the quiet-operation claim?
Noctua’s features page says the edition delivers the same ventilation performance as the original Flux Pro while being up to 8 dB(A) quieter. Treat “up to” as the best stated comparison under Noctua’s test conditions, not as a promise that every completed PC will be 8 dB(A) quieter. Noise will also depend on the CPU cooler, graphics card, power supply, fan curves, room acoustics and workload.
Rank #2
- Award-winning Antec Flux Pro chassis with state-of-the-art Noctua NF-A14x25 G2 and NF-A12x25 G2 fans for up to 8dB(A) lower noise levels, ideal for building ultra-quiet high-end PCs
- Fans can be installed using the included anti-vibration mounts for acoustic optimisation or screws for maximum safety in transport (3x 140mm front intake, 1x 140mm rear exhaust, 2x 120mm above the PSU shroud)
- Pre-installed fan extension cables and a premium grade NA-FH1 PWM fan hub for safely controlling all case fans in sync via a single motherboard fan header
- Supports CPU coolers up to 190mm height (NH-D15, NH-D15 G2, etc.) as well as 360mm and 420mm water cooling radiators both at the top and in the front, up to 455 GPU and 300mm PSU length
- Signature Noctua styling with brown rubber grommets as well as brown top and side panels, perfect in combination with other Noctua Edition products (e.g. Seasonic PRIME TX-1600 Noctua Edition power supply and Asus GeForce RTX 5080 Noctua Edition graphics card)
The individual fan specifications help explain the hardware but are not assembled-system test results:

| Fan | Speed range maximum | Maximum airflow | Maximum acoustical noise | Maximum static pressure |
|---|---|---|---|---|
| NF-A14x25 G2 PWM | 1,500 rpm | 155.6 m³/h (91.58 CFM) | 24.8 dB(A) | 2.56 mm H₂O |
| NF-A12x25 G2 PWM | 1,800 rpm | 107.3 m³/h (63.15 CFM) | 22.5 dB(A) | 3.14 mm H₂O |
These values are Noctua’s maximum specifications for individual fan models, available on the case specification page. They cannot be added together to calculate a PC’s noise level.

Price, availability and warranty
PC Gamer reported a $400 price at publication on March 17, 2026; that is a dated review price, not a current or universal regional quote. The available information does not establish present stock or pricing, so confirm both with a retailer in your region before planning a purchase. The review is at PC Gamer.
Warranty descriptions differ between the manufacturers. Antec lists a two-year warranty in its specifications, while Noctua describes the complete Noctua Edition package—case, fans and hub—as covered by a six-year manufacturer warranty. Because scope and regional terms may differ, use the warranty terms supplied for your market and clarify which company handles a particular claim.

Who should buy it?
A strong fit for
- High-end builds using large E-ATX-capable boards, long GPUs or tall air coolers
- Builders who want six quality fans included instead of selecting and tuning fans separately
- Users who value low-noise operation and are comfortable with Noctua’s distinctive brown-and-beige appearance
- Systems needing multiple radiator-placement options in a large chassis
Reasons to choose another case
- Your parts are compact and do not need full-tower volume
- You prefer a neutral or RGB-focused appearance rather than Noctua’s brown styling
- Your budget does not justify paying a premium for bundled fans and a hub
- You require independently verified whole-system acoustic or thermal benchmarks; the stated 8 dB(A) result is Noctua’s claim, not an independent test table
Pre-purchase clearance checklist
- Measure the motherboard’s actual E-ATX width if it exceeds standard ATX dimensions, and compare it with Antec’s 285 mm limit.
- Check GPU length with the intended front-fan or front-radiator arrangement, not against the 455 mm headline maximum alone.
- Confirm CPU cooler height, including the installed fan and any side-panel clearance requirement, stays below 190 mm.
- Match radiator length and thickness to the motherboard, memory, graphics card and PSU-shroud layout.
- Verify that the NA-FH1 hub and your motherboard provide the fan headers and control behavior you want.
- Confirm current regional price, stock and the applicable warranty wording before ordering.
Verdict
The Noctua Edition is meaningfully different from a standard Flux Pro when the bundled cooling package matters: six NF-A-series fans and the included hub remove much of the fan-selection work, while the large chassis accommodates demanding components. Its quiet advantage is plausible as a Noctua comparative claim, but it should not be treated as a guaranteed 8 dB(A) reduction for every build. The premium makes the most sense for a spacious, high-end PC where included fan quality, broad radiator support and low-noise tuning outweigh the case’s size, price uncertainty and brown aesthetic.
