The mini cooling fan USB plug can be connected to one of the USB ports of any android tv box to help cool the unit , especially useful in times of prolonged bx use.TV boxes have vent slots but do not contain an actual fan. As a result, prolonged use over a number of hours may cause the box to overheat. This can be especially hazardous to the box during summer months as the room temperature air passing through the box vents is already warm thereby having little of no cooling effect at all.
Ongoing overheating may result in the tv box freezing, getting stuck in a 'boot loop' and may cause permanent damaged. So the mini silent USB cooling fan is highly recommend to help to reduce tv box' temperature, which we have tested that the tv box can keep temperature around 40℃ -50℃!
