Hey b1172,
So long as the system isn't in an enclosed space with minimal air circulation, charging the device or leaving it running overnight shouldn't lead to overheating. Also, based on user reviews, fan noise is only most apparent when the system is under a heavy workload--i.e., when gaming, local video editing.
Please feel free to reach out to us with any other questions!
