> I've been wondering if it's dodgy hardware due to Thermal Loading. That was my first thought. After wading through tons of Multia links, I ordered an 18 CFM cooling fan from McMaster Carr to replace the existing 6 CFM fan. This made no difference on the reboot front :( It could also mean my efforts were too late and my RAM was permanently impaired by heat damage. > At one point I got a series of ncr0 firmware errors similar to those > mentioned earlier, shut the system down and let it cool for a while and > those problems went away. Do you have an internal drive? The first thing I did was move my SCSI drive to an external case. > Subjectively the box seems to stay cooler in a horizontal mode than vertical > in the little plastic stand supplied.

My fans were both pulling air upwards when the case was vertical. With heat's natural tendency to rise I would think vertical is a better orientation ;) (Note the power button is towards the top when mounted vertically) - Bruce ______________________ Bruce M.
