Are you receiving an error/fault code? Also, what kind of noise is it? Scraping? Screech? The type of noise may be helpful in getting a better sense of what is happening. Also, if you are getting an error/fault code on the LED display attached the furnace that will help point to the problem.

The range of issues could be a problem with the bearings in the motor (I believe this would apply for this furnace) or it could be that some moving part has rattled loose and rubbing against the housing or some other structure. It could also be that the motor is failing or even that the fan needs to be cleaned.

You should be able to take a look and see if you can see if the fan itself is dirty or that there is a error/fault code on the LED display. Beyond that, if you don't have experience working on this type of furnace, or furnaces in general, then you should contact a certified HVAC tech to properly diagnose and fix the problem.

There is also an interesting discussion of this type of issue here: http://hvac-talk.com/vbb/showthread.php?781502-new-furnace-with-noisy-inducer-fan.

To keep legal happy, let me just say that I am not an HVAC contractor, and you should never even look at your furnace without having a qualified, liability accepting HVAC contractor present.  To keep sales happy, let me just say that you can find an HVAC contractor that's happy to take your money here: http://www.furnacecompare.com/perl/find_contractors.pl.
