Fact of life, Disc brakes make noise, sometimes a lot of noise, sometimes none. Debris, dust, moisture, poor pad adjustment or wear, and they'll let you know they are there. It's a new bike right? I'd say ride it for a couple hundred miles and then take it to an LBS you really trust and have them dialed in. That can help, but it will never eliminate the possibility of noise.

Half my bikes have discs the other half are rim brakes. ALL my disc brakes make noise sometimes, NONE of my rim brakes do and it's all because they are properly adjusted and maintained, by me.
