Referring to Page 2 of the Thermal Enterprises documentation on the CP1-12726, the graph in the upper left hand corner plots Qc(W) vs dT(C). Look at the intersection point of the I=26A plot with the y-axis scaling of Qc. The value indicated validates the Qcmax noted on Page 1 of 243.5W. This device has a maximum cooling rating of 244W in round numbers, not 320W which I believe is hype, at a maximum power consumption level of (15.4V*26A).
If there is a 50mm square 320W Qcmax peltier in the marketplace, it's not this one.
