On the 166 -> 200 I put a nice layer of heat compound. the 200 -> 200 came assembled, I doubt they used compound... Looks like same brand on both. Next time I powerdown I'll try to remember to read the label. I have both in an enclosed rack, with a dryer hose running from window air-conditioner to the bottom of the rack. Temp sensors in rack typically show (farenheight): top: 80 middle: 78 bottom: 72 I've never seen the top get higher than 84. This rack has 5 systems running 7/24, external disks, tapes, modems, etc. -- Steve Passe | powered by smp@csn.net | Symmetric MultiProcessor FreeBSD
