Usually the fan doesn't bind very much in the shroud and is usually only rubbing on a high spot or two .

I have taken a Dremel and shaved the high spots on some of the shrouds until there is just a slight clearance. This has seemed to work fairly well.

I was like you and didn't like the idea of the fan taking the place of the Dremel being that the idea was to shave the high spots down anyway......
