No, he's talking about the CPU itself, not the whole machine, but you still have a point.  A significant part of the power used by a PC is spent running 
the fans, so just because the CPU is only using 10W (or whatever) doesn't 
mean that your actual power consumption is 10W.  And the more power your CPU is drawing, the more often the fan has to run.
