Clicking sound from 2015 SSD iMac?

Can you hear the low clicking sound if you crank up the volume? I put the iPhone close to the bottom vent on my iMac. This sound is more audible than the 1200rpm fan that some people complain about. I only hear the clicking sound in a totally silent room, but I'm still worried that something might break. If this was a smaller machine I'd just take it into a store, but the 27" iMac is NOT easy to carry. Also, it's quite far to the nearest Apple Store.

I'm a bit curious what it could be since I don't have a spinning hard drive. Anyone having any thoughts?
I bought the machine new 3 months ago, so it's not an affect of wear and tear.

Sounds like the fan playing up.

I will never buy the iMac until Apple allows to open the case easily. The MacBook Pro is better, at least you can clean the dust of the fan or replace it by yourself.

I think (but hard to decide) that the noise comes from the left side of the computer. But looking at the inside of the 2015 27" iMac the fan seems to actually be on the right side.
But the fan would be logical, since it's basically the only moving part.
I have increased the fan noise (iStat) to see if the clicking sound increases in frequency, but it's hard to detect when the fan noise increases. And unfortunately I can't decrease the fan speed temporary to see if the clicking sound decreases in frequency.

Well no iMac ever for you then. People want sexy and thin, not bulky with screws. Can you actually open up 2017 MBPs? I thought that was a thing of the past.
