So I have noticed that the plate at the back of my kegerator ices up (and is -3 F), but the beer in the keg is closer to 44. Obviously, this is not optimal in the least, and is probably why my beer hasn't been carbing fully.

I did a search, but all I could find was posts about using fans to cool the tower. Has anyone had any experience using fans or something of the like to circulate air within the fridge?

Subscribing because I've been contemplating the same thing.

I think most people blow the warmer air from the top down toward the cooler air in the bottom of the kegerator.

That could make sense...I'd assume any air blowing anywhere within the kegerator would get air moving around since it's such a small space.

It seems like the biggest issue for me is that it's cool at the back and warmer near the front. I may end up making a system that both circulates the air *and* cools the tower and post up what I end up doing.

You could use multiple fans that kick on when the compressor kicks on and have them blowing in multiple directions.

I have a computer fan taped to a piece of PVC pipe. I drilled holes on one end and put that end in the bottom of my keezer. The fan is taped to the top end. I have the air circulating from the bottom to the top.

I use a bilge fan to blow the air from the bottom up into my coffin box (it's a keezer rather than a kegerator). The advantage to this type of fan is that it's designed to run in a damper environment than a PC fan. Also it's a lot more powerful and therefore better able to push the air.
I use an Atwood 4" Quiet blower. The only challenge was that it requires a 12 volt 3 amp DC Power source. If you've got a rudimentary knowledge of electronics all you need to do is wire it up to a stepdown transformer from Radioshack (110v to 12v 3A) then added 4 diodes to convert it to DC power. It runs like a champ and keeps my coffin box cold.

I didn't know that's what it was called but looking at a wiring diagram for one that sure is what it is.
