Two silencers for mining machinery

1. Qitian 268e uses integrated graphics card and 865GV motherboard. Most batches do not have graphics card slots. It is rare that a few batches have graphics card slots. Even if there are graphics card slots, they are also AGP. It is absolutely impossible to have PCI-E graphics card slots

2. Muffler is generally used in cars or guns to rece the noise of car exhaust pipe and the sound of guns shooting. In fact, it can only be said that it can be reced, but it can not be said that it can be completely eliminated. No muffler can be achieved unless there is no medium to transmit sound in a vacuum environment.
