Larry O'Connor, founder, president, and CEO of Other World Computing, pointed to [http://blog.macsales.com/10206-further-explained-apples-imac-2011-model-hard-drive-restrictions|his own 2,000-word posting] on the OWC blog.
 
He scrupulously details OWC's testing of various drives in the new iMac, which essentially confirmed the conclusion of the original post by OWC's Michael Perry, which said that replacing a 2011 iMac's internal hard drive with a drive not provided by Apple specifically for that series will break the ''[onboard ]'' Apple Hardware Test and cause the fan to ramp up from a base level of 1,100 rpm to 5,600 rpm over time.
 
O'Connor also provides in his post a section entitled ''"Possible Solutions",'' which he wisely characterizes as '''NOT FULLY TESTED/Approved/Recommended, etc'''etc'''. Among his suggestions is to short the lines that carry the drive-temp info – but as he sensibly points out, "a consequence could ensue for obvious reasons."''' He also mentions HDD Fan Control which works with a drive's SMART interface to control fan speed.'''

it is important to note... This issue has zero impact on adding a drive to the SSD bay."
 
So you ''either pop for Apple Certification ('''not necessarily a bad thing, and a deductable business expense''') OR don't accept work on EMC iMacs, OR inform your clients of your lack of certification and the work around you propose to use.''
 
''If this Answer is helpful '''please remember to return and mark it''' Accepted.''
