Crackling Noise Macbook Pro Retina Early 2015

About three weeks ago my Macbook Pro Retina (Early 2015) that I only bought at the very end of July 2015, has been making a weird and loud crackling like noise towards the upper right side of the laptop. It sounds like a bad hard drive going out but obviously with the Macbook Pro Retina's having SSD that is not possible. I took it into an Apple store about 10 days after it first happening because I was in transition from one country to another, however during that time I did not use it at all. I took it into the Apple store, luckily right before I was going to leave the genius bar the noise started happening and they heard it. They didn't know what it was but they said they would take it and clean the fans and look in the inside. Diagnostic checks turned out picture perfect and no issues turned up there either. Fast-forward a week later and I picked up my laptop, they said they cleaned it but didn't see anything inside that would be the cause. I took it back hoping it was fixed, but after about 24 hours the noise happened again. The noise comes on randomly, sometimes I can use the computer for many hours before it happens (or doesn't happen) or it will start about 20 minutes after turning it on. I'm trying to fit in another trip to the Apple Store nearest to me but it takes a lot of planning due to my schedule and the time to get there.

As I write this it came on for the first time today but lasted maybe 3-5 minutes and has since stopped. The computer is not overly warm, there is no burning smell coming from anywhere and the fan is not running at high speeds. Just wondering if there has been issues with this type of noise or sound previously or if anyone thinks they know what it could be.

Thanks
