Whenever I have the lid open for a while and the freezer is running, I see frost on the lower foot of the freezer, and not on the upper walls. So apparently mine is backwards from your three! Also would exasperate the temp stratification. Update: I added a second duct and fan in front left...

So I didn't try the diffuser yet. I had printed a third piece of duct which brought the outlet to near the top of the small keg. This didn't seem to help much, still getting 50-52 °F pours. Then I pulled it out and flipped the fan so the fan pulled air down the duct from the top. This seemed to...

This is a freezer-on-top fridge. It will still need defrost cycles, and I wouldn’t recommend removing the drain.

Well after about an hour of reviewing my Fluids textbook and with a number of assumptions I got a rough pressure drop of 7.4 Pa across a 0.6 m tall duct that’s 75 mm wide. In short what it boils down to is I certainly don’t need to worry about a blower style fan at these flow rates. I’ll...

Yeah, part of the issue is that probably have is I had gone cheap when I bought the fan. I bought this one from Amazon, they are rated at 38 CFM, with 58 Pa static pressure. Sticking with the 120 mm axial form factor, this one from Digikey is 117 CFM and 98 Pa static pressure. Centrifugal...

Something like this?

Printed off two more duct sections. First one I did single wall as spiral vase print. Too flimsy, that’s why it was wavy. Was trying to save plastic. The two new ones printed with a 1 mm thick wall, and are decently sturdy for the application. I keep breaking legs off the fan though. With...

Here is the kreezer: 3D printed duct: Installed: I can feel air moving much higher than I could without the duct, so this is looking very promising. Another section of duct is on the printer now. That’s as high as I can print:

Yeah, it sounds like you have way more room between kegs, which helps promote natural convective currents. I don't have much free space. I decided to try a duct. I quickly made a couple models and my 3D printer is hard at work. There's probably easier and faster ways to try this, like tape and...

That was my first thought. Unfortunately, while the Torpedo kegs happily stack in whatever combination, the endless carbonation lid has a water ball lock fitting that sticks up in the middle of the keg and prevents the Torpedo kegs from stacking due to the height of the fitting.

Ah yes. That should be safe enough, for the OP's case, since they have a fridge/freezer combo. Caveat for any future readers who don't have the OP's fridge: If it's a minifridge with no freezer, or a chest freezer, don't drill holes from the inside either. In these cases, they almost always...

As do I, with my converted chest freezer. But the OP has an upright fridge/freezer they are converting, not a chest freezer.

I'd caution against that. They could (and probably do) have refrigerant lines attached to the outer wall of the fridge. Drilling an exploratory hole will let you know if there's a line or not, but not in a way you want to find out. A thermal camera could be used. With the fridge running, watch...

Another vote chiming in on "don't worry about it." The motor starter may fail a bit earlier, but that's cheap and easy to replace. My first kreezer was a freezer that was from the 1980's, and as far as I could tell, had been in continuous usage as a freezer up until I got it in 2020. It...

I don't have your fridge, however, the 5" is for air circulation. A CO2 hose will have no effect on that. That said, they might have refrigerant lines running inside the back and side walls. Unless you see either an exposed coil on the back, or there is a fan blowing warm air out of the top or...
