Hi, My Mac Pro use to run all the fans at 800RPM which was nice and quite and kept things pretty cool, but after installing Snow Leopard I noticed my system was warmer. So i looked up the Fan speed and they are running way lower anywhere from 499RPM to to 599RPM. Why is this? I dont like seeing my RAM getting so hot, and I have a Blackmagic deklink card and a highpoint 4322 in there so those fans are spinning since Im not pushing more cool air in there. Any thoughts?
