I installed a new security system in my house and put the NVR in our master bedroom. I did this before powering up and hearing how loud the unit was. A ticket to the manufacturer was fruitless so I'm wondering what I can do to quiet this thing down on my own. I downloaded an app and base lined the sound level with the case on at around 60 dBa. Simply removing the case took the level down to about 48 dBa, a very noticeable difference. I'm attaching pictures of the fan, case, and case fan grill and asking for advice on how to drop the sound level even lower.
TIA,
Steve
