Besides lower hdd temperatures, are any other advantages in an good airflow case (like 3700AMB case, with good wire management)? Isn't enough only one 120mm fan in the back?

ps: oh, and i'm planning to use an aluminium filter in front, removing the case's default one...

None that I've ever seen.



Almost certainly, unless perhaps if you're running a bunch of HDDs and a very hot vidcard.

That said, it really does help to have some sort of fan blowing air on the HDD(s). Even a tiny bit of air cools the drive down quite a bit. I'd plan on putting some sort of fan in front, even if it was along the lines of a 5V 80mm Panaflo L1A.

I have only 1 hdd, a Samsung drive and i don't have any problems with it's temperature.
But i have a 9800Pro (with silencer on low), and is very hot, radiating heat all over the place (including the cpu)...
