While 4.32 degrees is great a attic fan that can lower the temp ten to 20 degrees is better.
Guess what? That study found. Wait for it
Three percent savings in COOLING costs.

I think you're saying that either method saves about the same amount? Neither seems like a lot of savings for the investment. 1 - 2% of my electric bill comes to around $20 a year. Not enough to pay for radiant. With a fan, a net of about $10 a year. That will take a while to pay off also. Not worth my trouble I think.
