I think your ducted system is ok for your case(active cooling), but in reality your hard drive positioning in the case is a bad one if they were to get that hot.Well that one was a pretty crowded case. But it wasn't "Sealed"; actually the side cover was off when I burned my fingers reaching in to do, (I forget what). Don't believe it if you don't want to; but that is the reason I have gone to the trouble of creating "Ducted Fan HDD Coolers" for my computers ever since then.
