What thickness of plexiglass is best to use for a water block?
Ok, so about three months ago I bought a 168W peltier unit off of ebay. I wanted to fool around with the cold side, the only problem was that I did not have a large enough heatsink to disapate the heat. And thus the peltier would overheat after 20 seconds. So last week I decided to make a water block out of the heatsink, the design was very simple, encase the heasink in plexiglass and add two hose barbs. Now my problem is that I can't decide on the thickness of plexiglass I want to use, 1/16" would be nice but I worry that it will break, and 1/8" is a little more expensive. Any ideas?
