Mnpctech's Overkill fan grill designs continue to raise the bar. CNC machined from 1/2" thick aircraft aluminum. 4-5/8" opening for optimal airflow.
You can mount these grills over 120mm fans located on the top, front or your side panel. Note: Overkill grills may not fit over rear exhaust fans without major modification to your computer case chassis or side panel. Measure your case before purchasing.
Grill dimensions are 5.5" wide x 5.5" tall x 1/2" thick.
