I have a random, quiet, inconsistent length beeping sound coming from my server that I can not trace down. It happens at random intervals, and the beeps are of random length. It sounds very similar to a bios beep code, but a bit quieter and not a consistent length. Sometimes its one quick, short beep. Sometimes its a really long few second beep. Sometimes its a long beep and a quick short beep. I haven't noticed anything not working on the server, all seems fine. It does not sound like a failing hard drive chatter, which is the main sound google seems to point me towards.

Troubleshooting steps tried so far:

• ran memtest, passed

• removed GPU, still beeped

• replaced motherboard, same beep sounds

• redone thermal paste, temperatures are in check, <40C, still beeps

• Passed all short SMART self tests (running extended ones next)

• Looked through syslogs, nothing matches up timestamp wise with the beeps

• Persists through reboots

• Mobo: GIGABYTE X99 GA-X99-UD3P

Running HAOS as a VM

Seemed to start roughly around the time I added the 2 Seagate x14 drives?

forgot a drive

Did a prankster hide one of those beepers in or near it
