Agreed, small wall warts are cheap - maybe even "free" if an orphaned 'wart is already laying about ones home.

And, fwiw, the fan in the pic above would be much more efficient/effective if it wasn't laying flat on the floor...

Cheers!

It's not laying on the floor of the fridge. I have 2 Corny kegs in there, so I had to take one out to snap the photo. My PC fan sits on top of the left keg, pointing towards and into the draft tower. There's no way to get a photo of that.

Much more stable temperatures now, uses less electricity than before, and the $70 Johnson themostat is not needed if it's done right.

Of course, some people do the "passive cooling" method with 2 copper tubes (1/2" inner diameter) around the beer out lines inside of the draft tower + 2 more copper tubes coming further down into the fridge to bring even more cool temps into the draft tower. I am working on this method for my 2nd kegerator right now.

Now that I read the earlier post again there may be another issue. If your kegerator is just not getting cold enough even on the coldest thermostat setting, then yes the PC fan method may fix your problem by making the fridge cycle on more frequently.

Then again, if that doesn't work, then you could simply buy an external digital thermostat (Johnson Controls brand for about $70) that will cycle your fridge/freezer on and off within a range of about 3-5 degrees F.

Then cut the wires of the PC fan and separate the power from the ground in the same way. Before connecting, push the power converter wire up through your drain hole in the fridge, then connect the power and grounds together and seal with electrical tape. Bam!

It works for me, but I may get the hobby box, PVC, and plastic hose to make the tower even cooler.
Wow, super helpful! Thanks a lot man! I'll be doing this next week for sure. Hopefully it does work...that would be awesome.
