Just got this fan today. It fits securely in place on top of my xbox one with 4 plastic knobs that fit into the x box vents. Plugged it into usb port and it turned on after I powered up the x box . I am able to here it running but it is not annoyingly loud. I used my digital temp gun on it while the xbox was running and the highest temp was 93 degrees Fahrenheit. After I turned the xbox off the fan turned off in a few minutes. It seems to be well made and it should keep dust from building up inside of the xbox and keep it from over heating.
