I've transferred many GBs of data many times to my Late 2011 15" MBP and never heard the fans. About the only time I have heard the fans running on my Mac is when I was watching a Utube vid or doing some heavy photo editing.
Along with transferring data I have also reinstalled the OS, and other OSs then the stock version of OS X, and never had the fans run at Max speed.
Simply, IMHO, you have a hardware problem. You can ignore it or you can get a new unit that works correctly.
Apple has a 14 day No Questions Asked Return policy for full refund.
So the question is do you want a very expensive computer that may not be correct or return it and get another that May work correctly.
This is not normal. Reset the SMC, then test your MacBook Pro again. Follow these instructions - do not skip the initial steps. If it continues to misbehave return the MBP for a refund and buy another.
Power or other problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset:
