Noctua fans are very quiet and very efficient.

Alternatively, I had a fan on one TT that was connected to a small solar panel on the roof so that it ran whenever the sun was out without having to bother with a switch.

I'm a software developer. So I use my work debugging path on fixing stuff (which when it comes to stuff like this is a slow process, but cost effective).
I ended up buying a cheap fan from walmart (picture included) and placed it inside of the bottom access panel. I instantly saw some improvement and with that came to the conclusion that I'd install some fans. Then last week I decided to move the fan around in the access panel to see if it changed circulation strength. I moved it from the back right side of the fridge to the left and as much as I can't believe it, my fridge is currently on electric (setting 4) and is at 26 degrees right now (it's cooler here today in the morning at 66 degrees.
After moving it, we had multiple 90 plus days and I never had to put the fridge to the max setting to stay under 40.
So for anyone having an issue with the norcold 2118 fridge holding temp. The recommend the initial troubleshooting:
1) Run the built in diagnostic testing and use the manual to see if any errors are showing themself:

2) Make sure you don't have a block of ice in your freezer (if full-time should check this monthly and clear it out once enough build up happens)
3) Make sure you temp sensor is on the 2nd/3rd fin and about 1 to 1 1/2 inches from the top.
4) Buy a cheap fan and place it on the back left side of the fridge pointing up into the guts (picture included).
In the beginning, on 85 plus days my fridge could not hold under 45 and would usually go up to 50-60 at peak heat. Now I'm having to monitor it daily to make sure the setting is low enough so that I'm above 30.
Will be looking at the recommendations and installing fans so I don't have a power cord running on the ground outside into my access panel. But atleast I know the fridge can pull it's weight with the right conditions.
Thanks for all the commendations etc. Whenever I get the fans, I might add a video of the installation incase someone else needs to do it and doesn't know how.
