Mid-tower case for ATX and E-ATX builds

The Rosewill Helium Air RGB White is a steel and plastic mid-tower that accepts ATX, E-ATX, Micro-ATX and ITX motherboards. Three full-mesh panels supply unrestricted airflow to the interior. A 34 mm deep cable channel behind the motherboard tray keeps wiring tidy. Seven expansion slots and room for a 390 mm graphics card suit high-end components.

Sustained-load cooling capacity

Two 160 mm PWM ARGB fans at the front and one 140 mm PWM ARGB fan at the rear come pre-installed. The layout supports up to seven 120 mm or six 140 mm fans in total. Radiator mounts include 360 mm and 240 mm at the front, 360 mm, 280 mm and 240 mm at the top, and 120 mm at the rear. Dust filters on all intakes help maintain airflow over long sessions.

Thermals, noise and power draw

The mesh side, front and top panels let large low-RPM fans move air quietly while keeping component temperatures stable. PWM control adjusts fan speed to thermal load, reducing noise during light work. Front I/O provides one USB 3.1 Type-C, two USB 3.0 and a combo audio jack for convenient peripheral access.

Questions about this item

How loud are the pre-installed 160 mm and 140 mm PWM ARGB fans when the system runs all day?

The three pre-installed PWM ARGB fans — two 160 mm at the front and one 140 mm at the rear — adjust speed automatically via PWM, so noise stays low at idle and rises only under heavy load.

Which motherboard power connectors and ARGB header must my board provide for the case to work?

Your motherboard needs a standard 24-pin ATX power connector, an 8-pin EPS CPU connector, and a 5 V 3-pin ARGB header to control the pre-installed fans’ lighting.

Will my existing 360 mm radiator and full-length 390 mm graphics card fit together in this case?

Yes — the front and top each support a 360 mm radiator, and the 390 mm maximum GPU length leaves room for a front-mounted radiator and a long card simultaneously.
