Question s340 noise

[iwiw]

Both me and my brother have NZXT s340 cases from the same supplier and date, but mine makes A LOT more noise than his and I was wondering why? We both have the same specs and mine just makes a lot more noise when idling and booting up than his. I was wondering if there are some common problems such as some fans being loose?

If it's a rattling/buzzing sound maybe something is loose in the case and needs to be tightened. With the sidepanel off see if you can determine where the sound is coming from - check the HDD mount if you have a HDD and try unplugging each fan in turn to see if you have a fan that has dodgy bearings. If it's a fan, replace it.
