The two cards can be overclocked to much higher speeds I guess, but right now I prefer not to start taking riscs, the more cooling the better. On the PPC card there are two coolers, one for the PPC (original passive cooler has been removed) and the other for the 68040. An the processor on the Bvision usually gets pretty hot so a cooler may be able to extend the life of the Bvision :-)
The only downside is that the card is now slightly too big to fit in a desktop. I might be able to fit it after all but then I need to use a hammer and I´m a bit afraid that the PPC processor may not stand the pressure :-o
Oh, forgot to tell that the 3 coolers are connected to a power cable that has to be connected to the main power supply, so the coolers will certainly not take their power from the Blizzard as this might fry some circuits on the board ... :lol:
