So I picked up some ridiculous fans and they claim to be 215 cfm + 5.3mm H2O (i think), 61 dba @ 3000 rpm. Crazy loud and wouldn't ever likely run that high but for fun I wanted to test them against the fans already in the case. So I'm thinking I could do something like the following diagram and I would just need to find a way to direct the air from the fan into the tube. I would be doing this with water. I'll suspend the tubing between 2 parallel wood dowels with clips and use a smaller diameter tubing. Thoughts?
