It seems that what's also happening is that the hot air in the garage is being transferred to the water in the coils which warms the water in the cooler, thus melting the ice.  The water temperature in the cooler quickly becomes room temperature and the only "cooling" which takes place is the wind chill from the fan; which is what you would have anyway without all the plumbing.   With the plumbing, the coils actually impede the air flow and reduce the amount of air you're getting from the fan.

How's my amateur science holding up?   Amirite?  Shocked

Having been stationed at fort sill okla. back in the 50s, all we had in the buildings were evaporative coolers which is basically just dribbling water down the front of a fan. They worked great in the dry climate. Won't work where its humid. Didn't need all the tubing in front of the fan.

When I was a boy, I can remember my Aunt had a small box type fan, probably about 12"-14". It was designed with tubes and a reservoir on top. You used to get a tray of ice, crack it open and put the cubes in the top. There was a drip/drain tray at the bottom if needed. This was in the early 70's.

I have made one of the "fan over a bucket" type of coolers. I used an old Coleman cooler, (without modification), a small fan, two 4" elbows and a piece of OSB. I use reusable freezer packs instead of ice, it works easier for me. I only need to use it a few times a year but it does a good job of cooling me down when necessary.
I will have to post photos.
