Anyone notice that the fans that used to run silent are now audible? It's not full-blast, but I can hear the fans on my 2008 8-core Mac Pro which is sitting on the ground next to me -- that I used to be so quiet I had to put my ear up to the machine to hear them. Just wanted to confirm if others are noticing this, or if it's just me. It's the same amount of noise under any condition. I've got a 2008 Mac Pro 2.8/octo, just installed Snow Leopard on release day.
