Fan for DEC H7861 power supply?

[David Betz]

I found a replacement fan for the H7861. It is the same size and same  
wattage but it has only three blades instead of the five that the  
original had. Is this likely to produce enough air flow to prevent  
the system from frying itself? Or should I keep looking for a five  
blade fan?
