I think it's possible that we've historically mis-attributed memory errors to cosmic rays when in fact they were caused by heat. If you ran that machine in a hotbox at 85°C for a year I think you probably would have experienced higher error rates. Bonus points if you also force the data to swap out a lot so it gets transferred through as many data paths as possible.
