While doing some random tinkering, I found that some processes have a tendency to make my CPU overheat.

"cat /dev/urandom > /dev/null", to be specific. With that running on both cores, the CPU temp alarm tripped at 60C. With other processes, like Folding@home running on both cores, the CPU tends to stay somewhere around 35C. Is this something I should be worried about and fix, or is it nothing and I should just not run that command anymore? (I ran it as a stress test).

OS: Ubuntu 7.10
CPU: AMD Athlon 64 X2 3800+
2 GB RAM.

I think you'd be better off posting this in the Linux forum. I seen this discussed in various Linux forums but never with a reasonable clear-cut answer
