I changed the thread title as I have figured out how to mount the 2nd fan, and the unit is being replaced by a Coolit ECO II 120. I contacted Coolit because of some gurgling and temp spikes with the Eco ALC 120 and they are sending me a ECO II 120. They don't even want me to send the old one back. I only paid $29 for the Eco originally.
Best customer service ever. Coolit =
