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.
Replace your iMac's original hard drive with a 3.5-inch SATA hard drive or a lighting fast 2.5-inch SATA SSD with a NewerTech AdaptaDrive for dramatic upgrades in storage capacity or data speed while maintaining the original system's fan and diagnostic performance.

as advertised

I've been a longtime OWC customer and have bought everything from SSDs, external enclosures, cables, etc and their products have always been on point. I recently got my hands on a used 2012 iMac and the first thing I wanted to do was upgrade the spinning HDD to an SSD. this kit had literally everything I needed to upgrade the original HDD and while I was in there I went ahead and gate the machine a good cleaning with an air duster and decided at the last minute to upgrade the blade SSD as well. with the SSD upgrades and maxing out the RAM @ 32GB, this machine has a new life. thanks OWC!
