On Sat, Dec 18, 2004 at 08:12:02AM -0500 I heard the voice of Jerry Bell, and lo! it spake thus: > > I've started adding so form of cooling to all of my hard drives and > I've not lost one since (and I used to lose MANY). Many people > underestimate the effect that heat has on components. I heartily second the motion. I get all twitchy when I see people put hard drives in a system without a fan directly on them; some of 'em even put drives in places where there's no circulation at all! Y'know, the one part of the system with very delicate and very moving parts, and that's the piece they decide to cool the least! I always put my drives in these: <http://www.pcpowercooling.com/products/cooling/drive/bay-cool/index_bc3.htm>; and they've worked wonders. The increase in density (3 drives in 2 HH slots) is a nice plus, too; and with the fan, the density doesn't blow out the heat as well. Not the cheapest such things out there, but they're built like a tank and I haven't had a fan out of 'em die on me yet. The only thing I'd change about 'em if I could would be to adjust the way the front metal piece holds the filter on, so you can get it out to clean without having to pull the front of the case off. It's easy enough to hack together such a mechanism for home use of course, but I was thinking something more suitable for colos. Of course, it means I need to be more careful to get cases with lots of exposed 5.25" bays; I never use the infernal[0] 3.5"ers, except on specialty cases that already have a big fan in front of 'em. [0] Yes, that's what I really mean 8-} -- Matthew Fuller (MF4839) | fullermd@over-yonder.net Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ "The only reason I'm burning my candle at both ends, is because I haven't figured out how to light the middle yet"
