[QUOTE="chscag, post: 1452096, member: 46727"] You were told correct information. Your iMac (and mine) have a proprietary hard drive with special firmware and temperature sensor. If that drive is replaced by other than the proprietary Apple model, the HDD fan will run full RPM. However, it's my understanding that when the hard drive is replaced by an SSD and the cable is jumpered the fan will idle normally. The problem with doing that is it voids your warranty. Other World Computing has a turn around program where you can send them your iMac and they will install the SSDs or other Hard Drives and take care of the fan problem. I don't see how you can attach the SSDs via a FW cable and have them perform the same as if they were installed internally. There's no way the FW bus can match the speed of the internal bus. I understand the part about the internal to external but it's still doing i/o via an external bus. [/QUOTE]
