Not necessarily. For example, when a server is idle, Linux "halts" the
CPU between interrupts (instead of doing a "busy wait" loop). This
significantly drops power usage and heat generated, which can also mean
lessfan power.
So, a busy Linux server generates more heat and uses more power than an
idle Linux server.
I think FreeBSD does the same; I don't know about other OSs.

I don't speak for anybody but myself - that's enough trouble.
