Shrouds allow your fans output to cover more Rad fins and therefore help remove more heat from the water. To me it's simple, and I'll always use a shroud if possible. 2 degrees is more than I would have thought though. I've always run my fans shrouded, and I have no comparison results so thx for posting.

As an illustration of why I think shrouds help I took this pic the last time I cleaned out my rad:

I use wide hub 38mm Denki San Ace fans. Take a look at how small the deadspot is compared with the hub size using only a 25mm shroud.
 
There's an article of mine on shrouds and fans that ought to get published soon :D

Shrouds are good!
 
Thanks for the link Diggrr, I had noticed the same as Baditude (not surprising, as it his old rad setup;)) but it also answered my question of push/pull on the fan orientation.
