I have a 2011 27" iMac i5. I tried to install an SSD (along with the 1TB HD). Two problems: 1. Somehow, when replacing the LCD, the LCD Data Cable (part number 593-1352) got damaged beyond repair and cannot be used. I therefore need a replacement cable ASAP. I am in northern NJ. Any suggestions on where the part can be purchased. I cannot find it for sale anywhere on the internet. 2. I put the iMac back together (just left the glass off). Connected everything except the broken LCD cable. When iMac boots up, the fan spins FAST and LOUD. I can acess the computer using Log Me In and everything is working properly and disk utility sees the SSD (although I have not formatted it yet. What could be causing the fan to spin. I tried pulling the cable out of the SSD (but left it plugged into motherboard and also tried unplugging the DVD. The Fan keeps spinning full speed, even without these two devices connected (although the cable are connected to the motherboard. I am wondering if NOT connecting the LCD Cable could, by itself, cause the Fan problem. I appreciate the help.
