    I experience occasional bleep-like noises with my iMac. I have a 2015 4K iMac with 2TB Fusion Drive, so I was thinking that it might be the HDD. What do you think?

    Here's a recording. (It's greatly amplified, so ignore the loud background noise.)

    I just hear static. That’s a lot of background noise. Possibly there’s a click that sounds like a hard drive. Not sure about a beep?

    Regardless, run SMART Utility if you’re worried about the HDD. If it shows as passed you’re more than likely OK. Any warnings and it’s almost definitely in the process of failing: https://cloudfront.volitans-software.com/smartutility323.zip

    It shows passed for both SSD and HDD, so yay! It's hard to describe (and record with an iPhone), but it definitely feels like a higher-pitched noise, and different from the constant HDD whirring.

    Actually, I could hear the bleep -- sounded like a scratchy metallic sound that started at the highest peak about midway through the Soundcloud recording. No idea what might cause that.

    Yes! That's exactly what I hear.

    I've updated the recording, and it's much clearer now. (Recorded with the iMac itself, instead of my iPhone. Duh!)

    I hope you can figure out what it is.

    You say "occasional"...how often and is it while doing certain things on the iMac?

    It happens quite irregularly; on average every few minutes or so. The noises don't seem to relate to what I'm doing, although I hardly do anything intensive.

    Sounds like a cricket in there. Not a familiar computer sound for me, either.

    Even though you passed the SMART test it could still be the HD.

    Another possibility is a fan bearing. I wonder if a fan-monitoring or controlling utility could help diagnose. You could set the fan speed to a lower setting (temporarily...just for testing) to see if the noise happens.

    It's a beep. Doesn't sound like fan, or hdd. Odd...

    Sounds like its originating in the cooling fan to me.

    That would be my guess too. Sounds like metal on metal...

    Is it worth contacting Apple about this? I still have two months of warranty.
