My housemate and I made a DIY chiller using a water reservoir inside a fridge to cool tub of water that our carboy sits in. We have gotten it down to 12 C (53.6F) as a test of maintaining below room-temperatures and the part that is touching the water is at 12.5, but the top is at room temp (16.5). This is just a est run with a carboy full of 5.5 gallons of water.
The water only goes up about 4-5 inches of the carboy, but from what I know about liquid physics, shouldn't all of the liquid inside be 12.5? Does it just need more time?
We can't have too much more water because with more water we don't have the power to drop the temperature enough with my small mini-fridge.
