Eventually I tested both ways (on the same unit), with the fan inside the case blowing up/down.
Blowing down = 43C.
Blowing up (as they are shipped by BFL) = 39C.
Was this with case on or off? I've heard that it's only worth it to swap the fan if you remove the case, and run it bare. Either way, thanks!
