Handling HD Heat Loading

[feleven]

Just out of curiosity, what enclosures are people using to house all these fast-spinning, hard-working hard drives, and what kind of cooling are you using? I can't believe standard desktop boxes with one fan for the CPU and another built into the power supply can keep all those drives within their thermal operating specs. Or am I just being paranoid?

I ask because the five drives in the bottom half of my large desktop enclosure, stacked one over the other with very little space between them, get fairly warm to the touch when I'm in there poking around. I'm kinda thinking of adding a fan, but I don't want the added racket if its not really needed. So far my SMART monitoring says all is okay. But heat loading is generally a run-away problem - once it goes beyond a tipping point, it rapidly escalates to a crisis.

How is everyone dissipating your HD heat?

Server fans in a big black ugly atx case.. All screwed in tight.. I check em every once in a while.. I will be upgrading eventually when I get enough drives for raidz2.. My drives stay pretty cool..

MiniATX Fractal Design Arc Mini with 2 Scythe Gentle Typhonn in the front for hdds and 1 in the back for taking the hot air from the case and passively cooled cpu out.
Psu is a passive one. All fans @800 rpm. No heat, no noise.
