Just turned on my early 2015 rMBP and updated some apps from the App Store, specifically the iMovie update and some Yosemite updates and all of a sudden hear this loud jet noise which apparently was the fan. The CPU wasn't high either and never had the fan kick in before.... Should I be concerned about this - anyone have a similar experience

I had the same concern. I picked up my new 2015 rMBP this past Sunday. I installed Logic Pro and then while installing Final Cut Pro, the fan suddenly came on at what sounded like full speed. My theory now is that Spotlight was busy indexing the thousands of files that Logic installed (I installed all additional content). So, that was probably running when I was installing Final Cut. Plus, it was on my lap... see last paragraph.

My fan also comes on sometimes when running Geekbench, but not always. The strange thing is that it comes on instantly at full instead of ramping up.

The other thing is that the laptop will heat up if you use it on your lap ironically. The intake vents are located in a position that is easily blocked if on your lap. I'm coming from a 2010 MBP where the vents were on the rear and not as easily blocked. And if you have track pants on, forget about it. That really interferes with the cooling via the aluminum casing.
 
Usually if the fan kicks into high gear, it indicates increased temperatures in the CPU/GPU. On more rare occasions, the fans can spin faster, even when there's no increased heat. If that happens, try resetting the SMC.

I have Spotlight disabled though so it can't be Spotlight. Are you going to exchange your for another one or accept it as a random occurrence? I'm still within the return period so need to decide- this makes me worried there's something wrong with it now :confused:

Well, the fan hasn't come on any other time so I think I'm keeping this one. Plus, the screen I got is just perfect and free of any visible problems.

I've tried resetting the SMC, no loud fan as of now... but having issues with Wi-Fi dropping :(
