I know this post is old, but for anyone else in the same situation with a bad fan in an Ooler system, I had an issue with my Ooler system after about 2-3 years. The fan seized up and couldn't keep the water cool. Instead of paying $130 and waiting for the manufacturer to fix it, I found the exact replacement fan on eBay for $21.50 and swapped it out myself. It works like new again. The only caveat is that the connector on the new fan wasn't the same, so I just cut the wires off the old one and soldered it to the new one. Here's a link to the fan if anyone is in the same situation. https://www.ebay.com/itm/125401606126

The fan is model FD1238SL DC 24V 0.17A

I didn't really find any other info about it anywhere, so I hope this helps you get back to a cool night's sleep again.
