So I recently built a new computer using the Phantom 820 case and I've noticed a strange noise coming from what seems to be the front or front side panel of the case. It's a bit hard to describe but it's like a sort of pop or loud creak, almost like the metal in the case is shifting with heat. It's not a very common noise, as it only happens at most twice a day. Because it's so rare, I'm having a hard time pinpointing the exact location of the sound itself. At first I thought it might have been one of my drives, but it doesn't sound like any sort of HDD noise. I also think it might be my optical drive, as it is quite old, but the noise happens when there's no disk in the drive. Anyone have any experience with this? Thanks in advance!
