So they just sit around, taking it in turns to cool off? This is so unromantic it makes me weep. I paid good money for a new Mac with 2 duo-cores just for the blighters to sit around skiving.
I recall way-back-when, IBM introduced water-cooled CPUs. If memory serves, there was a serious problem with algae getting in the cooling system. (There's got to be a joke there somewhere.)
