AC Infinity Rack ROOF Fan KIT - Quiet Dual 120mm Cooling

In this review of the AC Infinity Rack ROOF Fan KIT, the bottom line is simple: it is a purpose-built, quiet cooling solution for standard 19 in racks that prioritizes low noise and reliable airflow. The reviewer found it best suited for AV closets, home theater racks and small network cabinets where maintaining lower internal temperatures matters. The kit's standout attribute is its near-inaudible operation combined with effective air movement, making it an easy recommendation for anyone who needs steady rack cooling without the drone of typical rack fans.

Key Features

• Quiet dual fans: Two standard 120mm fans deliver cooling while remaining nearly inaudible so equipment noise stays minimal.
• PWM speed controller: The included speed controller uses PWM to adjust fan speed without introducing additional noise from the controller itself.
• Rack compatibility: Designed for standard 19 in racks and roof mounting, or to replace existing rack fans for straightforward integration.
• Robust construction: Heavy-duty steel housing and spiral fan guards provide durable protection and a tidy mounting solution.
• Linkable programming: Compatible with CLOUDPLATE series fans so multiple units can share the same speed programming for consistent cooling.
• Balanced performance: Dual ball bearings and 200 CFM airflow deliver dependable cooling with a measured noise of about 26 dBA.

Who It's For

The Rack ROOF Fan KIT is aimed at small business and home users who operate AV racks, home theater cabinets or compact network racks and need quieter operation than stock fans typically offer. Installers who want a drop-in replacement or a roof-mounted solution will appreciate the 19 in compatibility and included hardware.

This is not intended for large data center racks or environments that require extreme high-volume airflow beyond the 200 CFM rating. Buyers who need active temperature management with advanced sensors or integrated environmental monitoring should look for more feature-rich rack cooling systems.
