Ticking Noise from my MacBook Pro

I have a 2014 MacBook Pro Retina 13in display computer, which began making a ticking noise paired with a slight vibration every so often under my right hand. I called Apple and had every diagnostics test run, and no hardware came up as problematic. I updated my computer and made sure everything was working properly in terms of software. Then I took it into the apple store, where they ran more diagnostics (none of which revealed any problem), opened it up and cleaned out some dust. This also showed no signs of hardware damage or misuse. Everything seemed to be in order, except the ticking still continues. It's ticking right now as I am typing this message!

It happens regardless of using the keyboard or trackpad, regardless of chrome or safari or no internet browser at all. Whether I have it hooked up to a hard-drive and an HDMI or without it, whether I am playing music or not, it happens. I cannot seem to figure out what on Earth it could be, and while my computer seems to be working fine, the noise gives me some anxiety about what it might be doing to the inside of my computer.

Has anyone else had this issue before? Any suggestions?

Hi,

It sounds very much like a fan just barely nicking the shroud as it spins (or a piece of debris in there).
