2015 Retina 15" clicking noise

I just received my 15" Retina MacBook Pro yesterday (the version that was released just a few weeks ago) and I've noticed a faint clicking sound coming from the top right of the computer every few minutes. At first I thought it was the HDD, but then I realized it's solid state. I looked around a bit and it sounds like it may be a fan issue. Curious if anyone else has ran into this/knows of a fix? Should I just visit the store?
