Macbook pro 2017 popping noise?!

Just got a 2017 Macbook Pro 13 inch with function keys about three weeks ago and I just started noticing in the past week a popping noise from both sides of the laptop. The noise happens randomly whenever I use my laptop and is not very loud, but pretty bothersome whenever im working or studying. Im not sure whether its from the speakers or not, but it seems to be coming from under both the left and right sides of the keyboard (more often on the right side, but still happens on the left). I looked on forums and saw that people were having a similar issue on the 2016 Macbook Pro but I have the 2017 and it still has the issue. The popping noise sounds very similar, but it is not nearly as loud on my macbook. I was just wondering if anyone else with the 2017 MBP had the same problem to see if this is a somewhat common issue or I was just unlucky and got a defective unit. Im thinking about waiting it out and seeing if a software update will do the trick before I take it over for an appointment but i'm also hesitant about the idea of having to repair a laptop that is almost brand new. For now, its bearable since the sound isn't very loud and doesn't happen that often (sometimes doesn't happen in a 1-2 hour period but other times happens two to three times or more in the same time span). The noise itself doesn't bother me that much, but the idea of the sound possibly being a sign of a larger hardware problem is what concerns me since I am a student about to start college and will rely on this laptop for at least the next four years. Please let me know if any of you have had the same issue or have any recommendations of what I should do. Thanks
