Do you have data on this? Adding a fan shroud to the Corsi-R supposedly does not increase energy usage or motor temperature:

I'm looking for data on the power usage and motor temperature difference from a 20" Hurricane in normal operation, with a 20" merv 14 on the back, a C-R and a Comparetto.

He has an addendum at the bottom where they tested the fans and saw no problems with a single filter. I... don't understand how they come to those conclusions based on the charts in the paper. All of the fans were >10ºC hotter and one model went up by 20. 15C is a lot for cheap, planned obsolescence consumer electronics.
- Cerium 4y agoThey might be cheap, but I have never seen a box fan fail, and I have a few in service for many years. Consider that they are designed for cooling in a window application, which means they must be able to survive operation 35C in direct sunlight. As an air filter, mine operates at 22C in shade. That easily makes up for the temperature differential due to load conditions.
