I took a nice size cooler(not a Yeti just a cheap Coleman) and filled it up with half ice and half water. all the way to where the lid would just close
I sat that cooler outside in the sun for three days and it is 90 plus with heat indexes over 100.
Funny thing is when all the ice melted it wasn't knocking the lid off or spilling out the sides.
