I was skeptical, but a fan does seem to help

Thanks for the post. I have the 120 but I do feel it is too big and airflow gets wasted. I like that the 80 fits right into the bottom. What I would do is put some tape around the bottom where you have that gap so that all air got into the can. I used painters tape it worked just fine. I think I am going to order the 80 to test it out I can always put the 120 on the top or use it elsewhere.

 

I don't feel that tape is needed. It's still cooling 20° lower on low, and could cool more on medium or high.
