Our family runs a supermarket. Recently, an IBM server was changed in the computer room. The noise is particularly loud when it is hot at noon, but it is small at night.

It is normal. It is because of the hot weather that all the accessories of the server in the computer room become hot, and the temperature control equipment of the server will automatically identify (above a certain temperature). At this time, the speed of the fan will increase, that is, the sound you hear will be louder. It is suggested that the computer room should be equipped with air conditioning in hot weather, especially when data processing in your supermarket is very important.

There are other ways to reduce temperature and noise. You can go to the server manufacturer (Zhengrui server) to search some documents about server cooling and noise reduction, and you can also do some backup processing!
