| Jerry,  I live in L.A.  Heat is usually not a problem here and I am using my 
original metal fan which I just stripped and repainted.  Do you know of any 
easy way to inspect (DIY) for stress cracks or potental failure points in the 
old metal fans?

i have have personally seen more stress related fractures on the original metal 
fans with severe body damage resulting than on the molded plastic kooler.  i 
would venture to say the stress related kooler failures are more likely because 
of engagement with something in the cooling plane which will destroy the kooler.
