well of what i read.. maybe this will help you out :
socket proc = about 50W (thats a OC'D PIII)
TEC's = say 156W -> 117W (cause of 75% = maxW rule)
MaxTdelta = 70C (depends on type of TEC)
2 TEC's CASCADED :
W endW C
PIII 50W
TEC1 117W 167W 9C
TEC2 117W 49C
ambient 20C
Tdelta PIII->TEC1 = 1 - (50/117) * 70C = 40C
Tdelta PIII->TEC1 = 1 - (167/117) * 70C =-29C
the second TEC only adds temp to the cpu-die, however if you place 2 TEC's parallel, u can add the wattages and have a stronger 1 pelt..
2 TEC'S PARALLEL :
W endW C
PIII 50W
TEC1/2 234W (284W) -25C
ambient 20C
Tdelta PIII->TEC1 = 1 - (50/234) * 70C = 55C
u see this has far better results than de cascade one..
better have this setup:
1 TEC CASCADED WITH 4 TECS PARALLEL:
W endW C
PIII 50W
TEC1 117W 167W -65C
TEC2/3/4/5 468W -25C
ambient 20C
Tdelta PIII->TEC1 = 1 - (50/117) * 70C = 40C
Tdelta PIII->TEC1 = 1 - (167/468) * 70C = 45C
-65C is a very CUWL temp .. but u have to keep in mind that a TEC becomes less effective when dropping to the -120C barrier.
and 156 TEC's arent that cheap.. say about 5x$30 = $150..
I think the best setup is a phase-changer on top of 2 or 3 156W TEC's .. something like -70C to -90C , depending on your phase-changer and compressor, etc

OC'ing is my middlename
