The almost finished fermentation chiller. Just need to add a coating of paint around it and she should be good. Connected is a $12 thermostat with the thermistor removed and attached remotely so it can be attached to the fermentor reading the temp on the carboy. Apparently in the pic it has fallen off. Fan is controlled by the temp and it all works just fine. Even on 90+ days it keeps fermentation right at 68F.
