TR3 & TR4 fan blades

[Doug Mathews <mathews@uga.edu>]

List,

I've been looking at my 3 and my 4 cooling fans......the 3 blades are 
really pathetic in terms of size & pitch while the 4 are larger and bigger 
pitch.

I'm thinking of moving the 4's fan to the 3 since the 3 is up on stands for 
a good while.

Any one have any experience with that swap they are willing to share?

Thanks

Doug
