Key Specs
- Airflow Volume: 78.86 cubic feet per minute
- Cooling System: Liquid (A computer's CPU generates heat while operating and requires a cooling system to keep internal components functioning properly. Air cooling uses fans to draw in cool air and exhaust hot air, while liquid cooling uses coolant-filled tubes and water blocks to regulate internal temperature more efficiently.)
- Fan Size: 120 millimeters
- Fan Speed: 1800 revolutions per minute
- Noise Level: 33.9 decibels adjusted
- Number of Fans Included: 2
- Lighting Type: None
- Product Height: 123 millimeters (The out of box height of the item. Height is measured as the vertical distance from the bottom of the item to the top as it would be primarily used or placed.)
- Product Width: 80 millimeters (The out of box width of the item. Width is measured as the horizontal distance from one side of the item to the other as it would be primarily used or placed.)
