If you take a 24V TEC 12A and put
12V on it does it then use 6A or still 12A??

24V 12A = 100% VA
12V 12A = 50% VA
12V 6 A = 25% VA

I want to use a drift 0.8 172W on 12V and
cool a GF4 with it. I need 80W effective cooling
on 40 x 40 mm. I already used to the search to
find out that it would give me 86W but I thought
that there was a linear correlation between V en A
with TEC's. But it seems to be very strange that
with 25% power consumption I would get still 50%
cooling power... Or is this an example of the fact that
tec are in efficient @ high A...
