Hello, I would greatly appreciate if someone could answer my following question: I have a late 2012 iMac 27" and would like to replace the mechanical HD with an SSHD. Can someone tell me if I need a special cable or can I simply use SSD Fan Control or a similar app to reduce speed of fans? Also I have an older iMac 21" late 2009 and have got an SSD in there and running SSD Fan Control, and that is working fine. What if I were to put an SSHD in there? Can I use the same software or do I then need a special cable?
