Even with a 15.2 volt, 226watts of Q TEC it will only draw 56watts of electricity at 6.18 volts.. but this is a 50x50 TEC that's rated at the lower voltage than the 226 watt40x40 TEC . The 40x40 will draw even less than the 15.2 volt TEC sooooo the 6 volts can’t be right .. But that’s no surprise .. It wont be being powered by 6 volts.. it will be powered by 12 volts that’s PWM’d.
Ok... im trying to do the math for the conversion, but i see its not as straight forward as it seems. As for the PWM'd 12V, i understand the term, but not how its implemented... googling now.(ok, i gotcha now)
On a slightly different branch of this topic, need to know if i remember right or am just way off, but i remember running fans off the 12V and 5V together give you a ~7V. (easy way to run a fan slower/quiter w/o a control). Would this also work for a TEC? It would get the voltage closer to the 50% needed (excluding amps at this time)...

This is because they most likely supplied the wrong voltage to it and killed the unit. I know that on my machine (throughout a 30min OCCT test) that it showed the voltage in the 6.0V - 6.9V range. Though this may not be the "operation" voltage, it is what is supplied to the TEC from the control box during sub-60C operation...Edited by phatman81 - 8/12/09 at 12:58am
