I've been pondering about the effectiveness of multile lower power pelts that equal the efficiency of 1 higher power pelt.

So my question is:

Is it more effecient to cool down something say 4"x6" with multiple lower power pelts that would equal to about 400W

or

Use 1 pelt that equals 400W?

I figure that maybe using multiple lower power peltiers would cool better given the fact that I would be using either 1 large heatsink that would be big enough to cover the multiple pelts or multiple heatsinks, one for each peltier.

Then again I also think that when using only 1-400W pelt with an equal size heatsink would maybe cool down 400w worth of energy better because of the smaller size?

I also have another question regarding peltiers as I'm slightly confused about.

I've seen peltiers of a certain wattage, but seen them in different sizes. So does the bigger peltier work better than the smaller one, even though they are both the exact same wattage? Or is the bigger one better because it would have a larger cooling surface area?

I've read around on forums and tried to understand the technical information written about peltiers, but it's kinda hard for me to grasp as they are TOO technical and I'm no electronics genius or scientist. So I ask here so maybe someone can help to explain in laymen terms for all of us to understand.
