Thanks guys Validus wrote: This is the main reason I designed the airflow how I did. Depending on how it works I can have the 'cold air fall' or by flipping the top fan it will than push the air out the top. Quick update... Its getting quite cold overnight so I figured I would take a week off and winterize my garage. 1 day and I managed to finish most of it. Im going to build a removable wall across the garage door.(were used to parking outside now...the shop takes priority) I forgot to grab some of the right tape so Im just using some painters tape overnight. Back to the build next weekend.... Everything is built in it, just need to cut the plexi and paint the case. I have the case stored away so it doesnt get damaged in the remodeling but I will get some completed build pics up ASAP.
