Well, the problem is, they didn't wanna spend the less than $10 per processor for the coolers that I wanted to slap on there. I mean, if a company is having cashflow problems to the point where they can't afford to write a check for $20, it's a good sign that it's time to leave, PERIOD. > I've seen some pretty funny cooling systems before.

Ahh yes... the server admins with degrees in thermodynamics... *snickers* As far as my example goes, my "office" had two A/C ducts and a fan. For a small 6x12 room loaded with hardware (6 servers, a Cisco 2600 series, pair of network hubs, 3Com/USR Total Control rack and the boxes to feed it with), it got majorly hot in there. Got even worse when I'd close the door (and tie it shut with a network cable, since there was no knob on the door, much less a lock) so I could get stuff done. --- Andy To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
