Vertical airflow Micro-ATX chassis

The Antec Flux M is a compact Micro-ATX and ITX case built around a vertical airflow platform that draws cool air from the bottom and exhausts it through the top. A steel and plastic frame with a 3mm tempered glass side panel houses up to nine 120mm fan positions. It targets builders who want high cooling capacity in a smaller footprint.

Sustained thermal behaviour

Six fans come pre-installed: two ARGB PWM units at the front, three PWM reverse fans at the bottom and one ARGB PWM fan at the rear. The bottom-to-top flow path keeps component temperatures steadier during long sessions because hot air rises naturally out of the 360mm top radiator zone. Cable routing channels of 59mm at the front and 49mm at the rear prevent clutter from choking the vertical stream.

Interface and expansion limits

The front I/O includes a USB Type-C 3.2 Gen 2 port for fast external storage. Internally the case accepts graphics cards up to 450mm long, CPU coolers up to 175mm tall and power supplies up to 160mm deep. Two 3.5in and two 2.5in drive bays provide local storage, while five reusable PCIe slots and a built-in GPU support bracket handle heavy cards.

Questions about this item

How loud and hot does the Antec Flux M get when the six pre-installed 120 mm PWM fans run continuously under load?

The six pre-installed 120 mm PWM fans (two front ARGB, three bottom reverse, one rear ARGB) adjust speed automatically via PWM, so noise and heat output scale with system load rather than running at a fixed level.

Which motherboard form factors and power-supply length does the Flux M support out of the box?

The case fits Micro-ATX and Mini-ITX boards and accepts PSUs up to 160 mm long, with a 13 A extension cable included for flexible PSU placement.

Will a 360 mm top-mounted radiator and a 450 mm graphics card fit together in this Micro-ATX chassis?

Yes, the top supports radiators up to 360 mm while the GPU clearance is 450 mm, and the built-in GPU bracket helps secure long cards without blocking the top radiator area.
