Reddit reviews Thermaltake Mobile Fan 12 External USB Cooling 120mm Fan with One-Touch Retractable USB Power Cable Box for Notebook Laptop Desktop. AF0007

How about a simple wire stand powered by USB? https://www.amazon.com/gp/product/B002OJN250/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

My Boss has this setup at his desk and I thought it looked cool, effective and geeky so obviously I had to get one for my battle station setup.

Just purchase this fan, glue on some magnets and you have a stir plate. It's big enough you don't have to mount it into anything else if you don't want to.

Couple thoughts: I would definitely go the keezer route. You can get a big chest freezer that can hold 3 kegs plus a CO2 tank for a lot cheaper than you can a mini fridge. I just saw one on the front page of this sub from costco for $100.

I did the whole fridge (full size) to kegerator conversation and it was terrible. I got an old fridge due to budget and it had a hard time keeping everything cold, it looked junky and recently crapped out on me which is why I have a keezer now. I've also read that drilled holes in the fridge can really impact its ability to keep the temp regulated.

You're also going to want to buy an external temp gauge as well as a fan to circulate the cold air.

Edit:

I get that budget is important but having a QUALITY kegerator/keezer is more important. Here is why: if you skimp on it, you're going to have a crappy beer drinking experience and you'll be wasting way more money than you saved (not to mention the frustration and embarrassment of serving bad beer to your friends haha I've been there). With that being said, you can definitely make one for $300.

Sorry forgot to link mine.

Yours will work too if you can power it.

if the tub is kept close to the fan, yes. Otherwise it’ll act like a greenhouse (likely regardless of the holes) and cause your beebs to rot. A small fan (something like [this](Thermaltake Mobile Fan 12 External USB Cooling 120mm Fan with One-Touch Retractable USB Power Cable Box for Notebook Laptop Desktop. AF0007 https://www.amazon.com/dp/B002OJN250/ref=cm_sw_r_cp_api_i_TnBXCb7E6G1DR)) could work mounted to the sides of the tub with the cable running out.

I had plants in an cabinet that had cracks between the doors and the sides that I thought would be enough circulation but many many things I kept in there rotted when I was out of town.

Do you think it would be better to go with the larger version? I can't tell if the motor is the same.

This might not be the most helpful reply but if things don't work out you might consider this Thermaltake USB Fan. It has a built in speed control and uses a USB for power so no wiring necessary. I used this to build my stir plate and it has done the job and ran me about ~$20 to assemble (Although it does spin pretty fast so you might be able to get by using the 80mm version.....)

I know it’s not about replacing the internal fan. But this is what I ordered this past week and connected to one of my Pro ports; it was easy and does the job very nicely.
