I put this down to no airflow restriction from having to suck through grills/filters etc.
That is just a guess though.
I'm guessing if a case is set up like mine (4 fans pushing air in and only 2 pulling it out) the air is gonna wanna be pushing through there anyway so the fans are more of helping it on its way rather than pulling it.
But then air flow can do some weird things at times
Anyway, I got nearly a 20degree drop with my H50 in the front over my stock cooler so dont see much point trying it at the back for a few extra degrees.... unless I try a little of that overclocking malarky you guys keep raving about
