[TenTec] Fan For Titan 425

[Stuart Rohre]

If you don't get an equivalent part number, measure the old fan 
dimensions, (square?), thickness, count the number of fan blades, and 
usually you should see a marking on the label of the voltage and current 
rating.  If you go to the Mouser catalog, you should be able to match 
the old fan to one of the current fans.  Pick a good ball bearing or 
better model for lower noise and longer lifetime.  If you match the 
current drain, voltage, and number of blades, you should be close to 
moving the same amount of air as the original fan.
