It's important to note that the rate of heat production will be lower

the lifetime of a given job will be slightly higher.

That is, it doesn't save any power at all, and it produces slightly more
heat in the long run.  But if you've got adequate HVAC you'll *notice*
less of the heat when you're sitting in front of the machine.


The resistance of the wire does increase with temperature, so there
may be some advantages to running at a lower temperature for longer.
I'm not sure if this effect would be enough to reduce overall power
usage, but it might be.
