In my quest to have a means to run a second concurrent ferment, I have been working on a peltier module powered chiller that can be fitted in a hole in the middle of a fermenter lid. Hit a little snag, but this is where I am at so far:
-Stainless outer tube
-copper tube and fittings for rest of system
-automotive windscreen wiper pump
-cheap Chinese water cooling dual peltier unit with heat sink and cooling fans.
-steel bracket to hold all components and switches

After putting it all together and hitting the power, the heat sink just got insanely hot with the cooling block not getting very cool at all. Thought I had burnt the module out but I tried running it at just 6 volts where it just reached moderate heat and the cooling block got down to a decent 8 deg.
I just need to get the full 12v of cooling power out of the unit so am replacing the heat sinks with two (relatively) ginormous CPU cooler units and hoping that will do the magic.
