I have seen that when a new unit(various parts) warms up for the first time, but it should not be overly strong unless the computer is in a low ventilation area.
If it is still like that in a few days or the system in unstable contact the supplier(since its new they will give you faster service) for an RMA
My earthwatts 650 had a funk to it for a little bit. It worked fine and supplied reliable power. I assumed it was just burning in and any oils that were from manufacturing were burning off.
