I've tried spacing fans away from BIPs (single 120).
Using MBM diode ratings - same temps shown when shrouding pull side, 1C lower when on push side.
If you're looking to reduce noise, fan on the pull side only (with air pulling into case), it seems that you can reduce fan noise slightly, particularly if you line the shroud with something noise-absorbtive in the high frequency range.
Of course, I could also have simply persuaded myself that it was a bit quieter this way - I don't have equipment to measure low levels of noise and, given that I was installing/uninstalling a fan+shroud inside a case, it wasn't possible for me to do a "blind" A/B test.
