This is what' i've learned.

Qc is 100W (should be 90 W)
Find the point were Qc @100W crosses various current rating lines at bottom of the graph.

Draw a vertical line up to the same current rate line above. This gives voltage the pelt draws to get that DT
for 12.3 V=Dt is 34 C
Cpu temp =Th- DT

TH = 25 C degrees (is the hot side of the pelt at Q total of 346 W. TH varies depending on how good your setup is)

25-34= -9 C
