I put a shim shroud in (hollowed out 120x25mm fan frame).
Reported idle temps remain the same 8 or 9C over ambient.
Sound is, hmmm... sound levels at this level (particularly without being able to do a "blind" A/B test) are really hard to judge. Is it really quieter or am I just perceiving it that way because I think it should be quieter?

PS: I was aware of likely interference (if from nothing else, than from the "struts" of the first fan) but really wasn't sure whether I'd have room. Turns out I do, but the bottom right corner of my mb is now pretty occluded. I looked at all the "bits" there and there don't seem to be any heat generators (mostly just connector pins) so I think I'm OK. If I kill the mb, well, I'll be unhappy, but I have been wanting an excuse to get one of those DFI Infinity mbs...
