  • @TheMrgoughy One side is always cold and the other is always hot. Reverse the polarity and they change sides. (Hot becomes cold and cold becomes hot)

  • that's pretty cool. How did you discover that?

  • hi so if i put the polarity one way it gets hot and swap it goes cold but do both side go hot or cold at same time or do each side do same thing, so cold cold one polarity and hot hot or hot cold ect you get what i mean

  • Hi, I have a few questions about your experiment

    1)what many watts did the peltier cooler generate?

    2)how many watts is your peltier cooler? (80W? 92W?)

    3)how many mL of water was that?

  • @razor21212121 Dumb!!

  • fake!!

    

  • @Faralite that may be caused by a heat sink not removing enough heat from it make sure to put a generus amount of thermal grease and and a fan to remove the heat from the heatsink or it could be a faulty unit but i would try this first then if it doesnt help then contact the person you bought it from

  • Oi, i have one question. I think i may have a faulty peltier because the corner of the cool side where the black wire gets quite hot. Does that also happen in your setup?

    It's weird 70% of my cold side is freezing the corner gets hot to the touch. Weird

  • @Elliotvisualeffects Or maybe he is using a lower power TEC. I mean there is no doubt that attaching a heatsink and a fan will remove heat from the hot side faster but you can't say it is too slow because he is using passive cooling.

    Also, it looks like 12V is being used which is probably lower than the 15V the module requires and so there will be lower cooling power.

  • @TheSupertecnology its a peltier element you can buy em off ebay.
