Query: Not enough cooling breeze

I bought this fan in 2011 for a 10'x12' bedroom in the southwest corner of the house. It replaced a 25+ year old four blade fan of the same size, but the new fan just didn't push enough air to keep the room comfortable in warm weather. The top speed on this fan matched the medium speed on the Hunter Quiet Breeze 44" fan I installed in another bedroom in 2012. I decided to upgrade to the 52" Low Profile fan, and its motor and five larger blades cool the room more efficiently.
