I've forgot to mention, but I had this idea too. I cooled the CPU and the cache
controller chip with a cooling fan (I hope this is the name for it :-) ),
because these two chips were the only ones getting hot. And there was another
cooling effect too: after I was tired of removing and installing the boards in my
case, I just let the machine run open on my desk without the case.
But nothing of this helped. The tests failed with or without cooling.
