We always hear customer feedback that the tv box is very hot and hot during use! The normal use of the tv box does not have a cooling fan, there is only a small heat sink, when the playback box is playing for a long time, the CPU temperature will continue to increase, the highest temperature may even reach 60-70℃, then this will cause the box video freezes, or stop working, etc., and the life of the box will be shortened.Use the cooling fan to match the tv box. It can control the temperature of box. We have done test experiments. Using the cooling fan, box plays for one day. The built-in CPU of the box always maintained at 40℃ -50℃. If it is used for a long time, it will not freeze, freeze, and the CPU will not be damaged. Sure It is helpful for extend the life of the box!RPM: 1200Noise: 18Cooling method: air coolingUSB interface: 1Colour:blackMaterial:plasticPackage Contents:1 Set x Top Box Cooling FanOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
