for those of you running dual 72W+ peltiers

[pen^2]

how do you power them? i am thinking of running 1 PSU each for the best results, maybe a bit of overkill... right now i am trying to pot the peltiers, but kinda stuck cuz i have no clue as to how to open this silicone sillant container. it is DAP branded fire-rated silicone sealant to be exact.

72 Watt peltiers can use 5-7 amps @12 volts each.
You want a power supply that can supply 15+ amps
continuously to power them.

Your typical 300 watt PSU can put out 15-17 amps @12 volts
If you used (2) 250 watt PSU that would be ok.

Some prefer to use a dedicated bench power supply at
14-16 volts, since this is what most peltiers are rated at.
This can get rather expensive.

What kind of container is the silicone sealant in?

Hope this helps.......

yeah, 2x250w was exactly what i was planning on doing. the sealant is in a bottle taht has a narrow nozzle on top... kinda hard to explain ~_~
