FANS – FANS – FANS
The ONLY way to make the kegger project work well is to use fans to circulate air inside the keg box.
Check the pinned topic about how to make the keg box colder.
Use an old, or new PC (personal computer) power supply.
The supply can be either dug out of an old PC or purchased online for about $15. The supply will power 4 fans, but you really only need two. One to cool the back of the fridge (external) and one to circulate air across the freezer plate inside the fridge.
Believe me, it does work!
I have now gone through 12 half barrels since last summer (2005) and except for an occasional power outage which turned off my fans, the keg box stays between 34-36′ F.
The perfect temp for Miller Lite.
