If the fan is not spinning then it should not be making any noise. Peltier coolers are electrical in nature and do not make any noise, but since one side of the cooling solution creates a good deal of heat fans (or water cooling) is used to address this. When the fan stops, search around for the source of the noise. It is highly possible that if you bought a pre-made machine with this type of cooling in place, then it also likely has a decent video card, which will normally make a good deal of noise. System fans can also create a good deal of noise depending on their rating.
