New 27 inch iMac fan issue

I just purchased a new iMac 27 inch and the cooling fan is running constantly on high speed. Voice Over is also activated during initial start up and login. I've searched the forum and spoken with apple support. I submitted a disk image for the software engineers to research and I was told that it would be up to two weeks before hearing back from the support technician.

Specs:

4 Ghz i7, 8 GB ram, AMD R9, 3TB fusion

Here's what I've done so far:

Reset the SMC, reinstalled El Captain, Updated El Captain to 10.11.1. None of these has worked.

I'd be very grateful for any advice. Thanks in advance.
