What you saw was a "kernel panic" which is most often caused by the  
hardware malfunction, external USB devices or bad RAM. According to  
your description, it looks as if it iwas caused by the geforce card  
overheating because of the failed cooler, and it may have damaged  
something along the way, although I'd say it is not likely. It also  
looks like your ATI card is damaged as well - the screenshot you  
showed is a typical symptom of a bad RAM on the graphic card. You  
haven't experienced messed-up display with the geforce card, right?
What I'd do, it is replace the fan on the geforce card, and put it  
back in. I would also remove all the RAM sticks from the Cube and  
test with one at a time (it may be that the heat generated by the  
geforce card damaged one of them leading to the kernel panic error.  
You may try that with an ATI, but you may be daling with two  
unreleate dthings here (ATI display messed up beacuse of the bad  
card, and kernel panics caused by something else).
