    It's been going on for an hour and I can't figure out why. Searched and it appears some have had fan issues, I can't tell if it's a fan or a drive. It's on the right side of my keyboard close to the power button, at least that's where the sound appears to be coming from.

    I ran the Apple Hardware test, it errored out the first couple times, but I'm guessing it's because I didn't have it plugged up to the wall. Once i plugged it in it ran fine with no bad results.

    I downloaded and ran iStat and it looks like my fan on the right is running about 2100 RPM and the left is 1900 RPM...so I'm guessing it's not that? I repaired permissions, restarted, shut down, etc. This is a constant hissing/grinding/whirring sound that is driving me nuts!! Any suggestions? It seems I'm going to have to take it in to the Apple store. But any ideas are very welcome.

    It's probably not the drive, because the MBPr has all flash storage. Sounds to me like you might have something stuck in your fan...

    The fans are the only moving parts inside your computer. Take it to an apple store

    Any way to get it out without taking it to a store? Probably not, but worth a shot.

    You could try light shots of air towards the fans on the computer… if that doesn't work I'd take it in.

    Compressed air worked. Back to running silent. Much appreciated!

    Welcome ;) I'd probably clean it out every now and then just to make sure.
