Inspiron 17 5000 Series Too Noisy

I have a brand new Inspiron 17 5000 Series and it is so noisy. As soon as I turn it on, the fan or

something is going non-stop. I have updated the BIOS made sure it is well ventilated and have it just sitting there not doing anything and this fan is going and going.

It is so loud I am thinking of returning it because I can't bare to hear it constantly running when I am doing nothing but reading emails.

Any ideas of what could be wrong or is just the way new laptop are? I have an older Inspiron 17 and it never made this much noise unless it was processing something.
