As for temps - yes you will get sub ambient (if you have a powerful TEC) but the cooling of the TEC required is very large.
If i was to do it - from what i have read - your better off with a dual loop - the one with the CPU etc + cold side of the TEC and another loop just to cool the hot side of the TEC

The input voltage is really what determines how efficient they are. It is pretty easy to get a TEC to a COP of 3, but running them at their default rated voltages will indeed give a very inefficient result.

the pump makes very little heat and it works best by pushing the water not pulling.

loops should always go res>pump>rad>everything else>res

any heat made by the pump will be disipated by the radiator and the liquid will be coldest right before the CPU block just as it should be.

(that is why i said to put the tec between the rad and cpu earlier)
