There is a thread, maybe more than one, on this site about how to deal with fan issues (the fan running at full speed) after installing an SSD. The problem with this topic is that it seems every post on this subject is about two to three years old. Also now if you bring up the subject everyone will tell you about one of a few software solutions. So what I'm wondering about is how to by pass the HDD fan sensor on a late-2012 27-inch iMac. I have heard that you can short the sensor and by doing that bypass the fan problems (since this is what Apple does when they install an SSD. But I have never seen a picture of this before. Or an explanation of specifically how to do it. Any information about how to bypass the HDD fan sensor with a hardware solution (please no software solutions), would be greatly appreciated.
