I installed the ssd and now I have the cpu fan running at full blast. it seems to start about 10 seconds after the iMac starts. I've go far as to undo and redo all of the steps TWICE. I've also detached the ssd and the cpu fan still runs at full blast. I've also tried the software solution and nothing works? It seems to be running at 3800 constantly. Any ideas? Please HELP!
