The tray installs with 3 screws on the rear for secure clamping and added rigidity.

Hot Swap 120mm Fans

Simplify maintenance and reduce downtime

Our hot swap fan assemblies are made and stocked in-house in the United States for lower cost and immediate availability. You can specify your favorite brand or as simple as required airflow and our ATO process will insure proper fans are procured and integrated as required.
