Kryotherm results (75W heatload, Ambient = 25C, Rh = .18. Rc = .1, Rins = 1) for a Drift 1.15 pelt (120W, 24.6V)
@24 volts:
Thot = 73.3
Tcold = 25
Tcpu = 31.8
@21 volts:
Thot = 65.1
Tcold = 23.8
Tcpu = 30.7
@15 volts:
Thot = 51.6
Tcold = 25.3
Tcpu = 32.1
It's worth pointing out that going from 15 to 21 volts has a cost of about 75 additional watts dumped into the loop.
