HS 453DX does generate more heat on the surface because this is how thermal cooling works. Other NAS use FAN cooling with fan speed settings controllable. But in my opinion, HDD generates more noise than fans. For absolute silence you need SSD.Qnap doesn't have plans to release something soon, but towards the end of the year, 253D should be announced. In meantime, 53Be is indeed the best NAS in the rage.I hope this helps.
