I'm planning on running one of my 80W pelts on the NB and I will build a simple PI-regulator to control a high current transistor (or likeworthy component) which will apply the right amount of voltage for the pelt.
To avoid condensation i vill use two tempdevices, either thermistors or Pt-100, in a wheatstonebridge. One on the coldplate and the other outside the case to measure roomtemp.
This setup will keep the coldplate at room temp all the time and will not require a separate PSU.
