I don't think cpu temperature is the problem in my case. The fan is working well and the box is running stable with high load for hours/days while there is no heavy disk activity. But copying files for some minutes kills it reliably. But I will try to watch this more closely. Might running the CPU with 100MHz instead of 200MHz to keep it cooler be worth a try? I could try to find another CPU to put into my machine, too.
Greetings Florian
