Just got my 2015 MBPr 2.9 8g 512
All I've done is email and surf the web and it's super hot. My wife's 2013 MBPr is cool as a cucumber doing the same thing. Mine is too hot to keep on my lap.
Mail, chrome, evernote are the only things running, plus dropbox in the background.
Fan alternates between running slow and approaching liftoff speed. Never just off.
No problems with my 2014 11" Air that I just replaced.
Any ideas why this is so freakin hot?
 
Easiest solution is to call AppleCare to see if they can correct the problem for you. If that doesn't work to your satisfaction (doesn't fix the problem or tell you to take it in for repair), return it for a new one, since you have 14 days no questions asked return policy.
 
Use Activity Monitor to see what processes are using a high percentage of the CPU. If most of the time is in idle and it is still getting hot return it.
 
As mentioned, Chrome is not friendly with the MBPs, that's probably one of the reasons why its running hot. Try using a different browser to see if the results are better.
 
I run chrome as my main browser for years now, no real issues. As stated though, there is lots of housekeeping on new macs, filevault (if enabled), indexing and you did mention dropbox - dropbox is a mega resource hoarder when it is downloading, indexing and syncing. Once all of that is done, the machine should settle down.

HAHA. I'd agree except my older air ran the same stuff with no problems.

No, it's Chrome. I don't know what exactly it is about Chrome, but it did the same thing to my 2015 MBPr 2.9Ghz 16GB. It caused my mac to consumer 30 watts (!) of power on battery and caused battery overheat warnings. I even took it in to an Apple store to get looked at.

Their verdict: Nothing was wrong, except for Chrome.

Sure enough, if I use everything BUT Chrome, the Mac doesn't heat up.

I can only some it's some sort of bad interaction between the way Chrome uses resources, and how Broadwell CPUs allocate them.

And no, Spotlight had nothing to do with it. Spotlight's indexing had finished weeks before, and I could SEE Chrome hogging up everything in the Activity monitor.

Dump Chrome, and your problem will go away.
