Hey everyone! I recently built a new PC with all new components, except for four 3.5" HDDs. I've started noticing a constant "heartbeat" noise that goes off every second. It sounds rhythmic and doesn't seem to stop. I'm trying to pinpoint where it's coming from, and I suspect it might be the fans or the hard drives. I've linked a video [here](https://imgur.com/a/3YheM9x) (turn the volume up). Any ideas on what this could be? Thanks in advance!

That's strange! Do you have an AIO cooler installed? That could be the source of the noise.
