Hello! since my 8800 GT is very noisy under load, I wanted to replace the stock cooler with a better one. But I am reluctant to try anything because I had bad experiences with that in the past. One problem is that there is only very little room in the Mac Pro (2008). Or can I mount the gfx card in the second slot? So has anyone successfully replaced the stock fan with another one? With what results? Maybe I also would try to overclock the card, if the cooling power is enough. Any help would be appreciated! TIA!
