This is my first post here on the forums! I just got my MacPro Back from Apple, they had to replace the graphics card. Everything seems to be working alright, but all of the fans are running and will not stop! They all run at a constant speed and I have not noticed that they speed up or slow down. They will stop if i place the computer in sleep mode. I ran the apple diagnostic, unplugged everything, switched to the other monitor port, updated all the software and pulled everything out and reseated everything in the computer. Nothing has done the trick. Any help would be great. I just hate lugging that thing to the store. Thanks!!!
