They all have nVidia Quadro FX cards in them and they all kernel panic regularly. sapphire (and even the screen saver) so it might not be heat after all. I'm experiencing the same types of issues with Kernel Panics on my 2010 Mac Pro with 3 NVIDIA cards (two GTX285's and one Quadro 4000). Some days I'll have 6-7 KP's a day while actively working on the system, and some days, I won't have any KP's. I did start to notice a weird pattern where I'd go off to lunch sometimes, and come back to find that the machine had Kernel Panicked for no apparent reason. It didn't seem to matter if I had an active render going, or if I all I had running was Mail.app and Safari. I started keeping a running log of everything that I did to troubleshoot the problem (i.e. driver installs/uninstalls, app uninstalls, System Preference changes, etc). And I seem to have narrowed the problem down to the Energy Saver settings. For some reason, my Energy Saver settings were set to have the default screensaver kick in after 30 minutes, as well as putting the hard disk to sleep (I'm guessing this got reset at some point in the recent past when I zapped my PRAM, thinking it would clear up the initial KPs). My system drive is an SSD, so I began to think that the system freaked out when it tried to "spin down" the SSD. Unfortunately I disabled both the screensaver as well as the disk-sleep options at the same time, so I'm not positive which one of these is the actual culprit. But since disabling both of these Energy Saver options, the Kernel Panics have been noticeably minimized (I've only had 2 KPs in the past week…which is still more than I feel is normal, but I'll take it over having over 5 a day!).
