    Improve Performance and Capacity. Upgrade Your iMac with Confidence.
    OWC's in-line solution is the only hardware digital thermal sensor on the market allowing a third-party SATA drive to be installed in your iMac. A convenient, plug-and-play cable, the In-line Digital Thermal Sensor eliminates fan noise and maintains proper system fan control through the iMac's System Management Controller. This innovative device is designed specifically for the iMac, requires no software hacks and ensures compatibility with Apple's built-in diagnostic processes.

    Using an OWC Internal HDD DIY Kit (sold separately), replace your iMac's original hard drive with a high-capacity hard drive or a lighting fast SSD with a NewerTech Adaptadrive, for dramatic upgrades in storage capacity or data speed while maintaining the original system's fan and diagnostic performance.

    Already have the tools? Then purchase just the OWC In-line Digital Thermal Sensor.

    Rating: 5/5 Great tools for the iMac! October 24, 2016 I had to replace the disc drive in my 2012 27" iMac. I had done this before on the 21.4" Imac. THis i Mac is completely different. I followed ALL of the instructions and was able to replace the 1 TB disc with a larger 2 TB disc. The install and re-assembly went smoother than I had expected. This tool kit had everything I needed to do the job. A++ for OWC!

    Rating: 5/5 SMC compatibility kits August 25, 2016 the product was "as advertised" , shipped promptly, and the sales rep i dealt with was knowledgeable, and i will order again other items. I've been buying here for 10 + years, and on the few returns i have had to do, it was painless, a big plus.

    Rating: 5/5 Worth all the effort! July 6, 2016 It seems a bit scary from the instructional video but it is really not that difficult. It's worth the price and the effort. Now disk space is no longer a constant issue for me anymore.

    Rating: 5/5 Everything provided and worked as demonstrated December 4, 2015 The kit came with everything needed and the video was straight forward enough to get the job done.

    Successfully installed and upgraded the HDD and iMac is working well with the upgrade.

    Only thing I would recommend is to supply double the amount of adhesive strips as they are easily damaged. There are 3 or 4 extra in the kit, but I think the strips should be doubled for those times you may want to remove some and re apply if you got the placement wrong.
