To clarify, I am NOT building a tower fan configuration. I am just looking to get better air circulation in my keezer build to try and even out the temps. That being said, I'm curious what the best place to mount a 120 mm computer fan would be for this? I have a 7.1 cu ft (I think) freezer that I built a collar on and used to mount tap shanks, rather than drill through the wall of the freezer itself. It holds two corny pin-lock kegs comfortably, but I think a small fan would benefit me in terms of temperature distribution. Is it better to put the fan near the bottom and push cold air upwards or near the top and push warmer air downwards? I am leaning toward the former, if only for reasons of thermodynamics.
Air circulation fan in keezer...

I do not mount mine. I simply set them upright where ever there is room and will promote the best circulation. This is what I have:

I do not think it really matters if it is at the top or bottom. In in inclosed space barring any thing blocking airflow, it will circulate air throughout from top to bottom wherever the fan is located.

Doesn't really matter. Just as long as it's moving air, you're good. It's a small area.
I was having some circulation and foaming issues with my new Keezer. I fashioned this thing out of cardboard and duct tape to see if it would help. Temps are pretty equal top to bottom now. Someday I'll make something more permanent but this is doing the trick for now. I am just using an old PC fan wired to a cell phone charger and a 7.0 cu GE freezer. Fan is attached to a couple angle brackets which are attached to the collar. It pulls enough cold air up to do the job.

Gathering data...........Me likey!
I simply placed my fan on the shelf and it seems to have evened everything out without a rig like that. I wouldn't suggest changing it now, but might be more trouble than it's worth to build for anyone wondering.

Certainly it's worth trying simpler solutions first. And a 120mm 12vdc fan screwed to a block of maple and blowing from the hump into the maze of kegs has worked adequately for my 13cf keezer.
But that thing has a certain geek factor in its favor
And as noted in another thread, the stack is blowing at his shanks and apparently resolved a first-pour problem.
So, two thumbs up!
Cheers!

This I will concede.

I have a 3 tap 6.8 chest freezer with 8" collar, insulated with 1" rigid insulation. I had a fan for a while, just didn't see where it made any difference. I have 10' lines and moving them around and finding the right place for the lines made some difference in pouring consistency. I don't get much condensation - I use one of the gel crystal gun safe dehumidifiers.
I use 2 squirrel cage fans mounted under my freezer hood.
They pull air from the freezer and blow it right onto my taps and beer lines. Keeps the air moving and does double duty at keeping my beer lines cold.
Highly recommended!

fwiw, at some point you have to start respecting the thermal dissipation of the air mover versus its functionality. If you're dumping 10 watts inside a keezer just to keep the air moving when a sub-1 watt 120mm peecee fan would do, you're probably not well served...
