Hi,

I can recommend Papst and Y.S. Tech fans at 
"http://www.papst.de" and "http://www.ystech.com.tw". Both offer 
fans of different sizes, cfm, voltages, noise that are guaranteed to 
work for at least 80.000 hours (must be about 9 years) at 40=B0C 
permanent running. Papst fans are more expensive but the company 
has a very good reputation for building high quality fans and highest 
quality electrical motors that are used in high end turntables and as 
the company is in Germany it is easier to contact in the case of 
problems.
