Benchmarks: Noise
This is a potent gaming PC designed to be as quiet as possible, and the proof is in the playing. When idle, the 3XS Z370 Vengeance Q is barely audible in a quiet room - you don't realise it's on until you go up close - and though you can hear the GPU fans when gaming, it's little more than a constant, steady hum.
Once you become accustomed to rigs as quiet as this, it's hard to go back to the jet engines of old. The Scan machine is so quiet, in fact, that the occasional churn of the internal hard disk is noticeable. Another reason to consider taking an SSD-only route.
