I am actually used to the steady hum from the full size case fans that I use but even without them, the dual CPU fans on my two systems with big heat sinks are practically silent and definitely more silent than 3.5 inch hard drives unless shock mounted.
It does not take much air flow through the largest heat pipe coolers to maintain a 65C Tj even at 120 watts although this emphasizes the problem with motherboards which do not control the fan speed well that GCP brought up.
