The fan sound of Shenzhou notebook is loud, it depends on how loud the fan sound is. If the sound is used under normal conditions, it may be a problem with the fan. First remove the fan, clean the dust inside, and then power on. If If the sound is still loud, the fan motor is broken and can be replaced. If the sound is loud when playing games, this is normal because the CPU dissipates a lot of heat when playing games. At this time, the fan needs to run faster to dissipate the heat as quickly as possible, so the sound will be loud.
