Other World Computing today introduced the OWC Hard Drive Do-It-Yourself (DIY) Kit for all 2011 iMac and 27″ 2012 iMac models. The kit enables iMac owners to replace the factory installed internal hard drive with up to a 6.0TB hard drive for expanded storage and backup capacity. Fully supported with step-by-step video and installation tools, the kits feature a custom power cable with an in-line digital thermal sensor that ensures proper factory fan operation and full compliance with the Apple diagnostic testing.
The Problem: Custom Drive Firmware
With the introduction of the 2011 iMac, Apple factory drives contained custom firmware that communicates thermal data to the System Management Controller (SMC). Standard, retail replacement drives do not contain that firmware, and Apple does not make it available to third-party manufacturers. Without proper communication, the SMC is unable to monitor hard drive temperature to regulate iMac fan speed. As a failsafe, the blower fans run at full speed and the Apple Hardware Test will report a failure. Despite various ‘hacks’ and workarounds (one that simply disables SMC monitoring, which can potentially lead to hard drive or system damage) the best solution had been to skip the upgrade and settle for Apple’s factory drive.

The Proven Solution: OWC Hard Drive DIY Kit w/Thermal sensor module
The OWC Hard Drive DIY Kit provides a custom engineered digital module with a thermal sensor which installs in-line between the new drive of the customer’s choice and the existing Apple factory cabling. The thermal module is programmed to communicate drive temperature data to the SMC in a similar manner as the original, factory installed drive. Now all 2011 iMac 21.5″ and 27″ owners, and all 27″ 2012 iMac owners can:
- Install any standard 3.5″ Serial ATA hard drive with capacities up to 6.0TB
- Retain proper cooling via SMC bay monitoring and fan speed management of the hard drive bay per Apple factory settings
- Pass Apple diagnostic testing
“The Hard Drive DIY Kits for 2011 and later iMac models represent OWC’s steadfast commitment to the DIY upgrader/servicer,” said Larry O’Connor, Founder and CEO, Other World Computing. “Our kits represent the only complete, proven solution for obtaining higher storage/backup capacity while retaining proper system operation.”
