Yeah somehow I don't see using a resistor to "use up" 5volts as being a particular power saver but then - I didn't so well on that circuitry midterm -stupid AC current, I never understood you -Although I didn't think my DC was that bad :P
Or does the pelt run "better" at 85% or just better in the cooling

ower use ratio?(Which is what I thought BigBen was implying)
