Rating: 5/5 Works perfectly! July 8, 2018 I ordered the temperature sensor for an SSD upgrade in my iMac. I finished the upgrade in 45 minutes and was able to observe the proper functionality of the sensor when I was rendering video files in final cut pro. PS: this solution is less expensive than the ones from the the competition and easier to mount.

Rating: 5/5 I've got my iMac back! June 26, 2018 I have a 2010 iMac and for YEARS (literally), the fan has been going in high speed for short bursts, long bursts and intermittent bursts. Sometimes, it sounded like it was revving it's engine. I finally brought it in to be serviced and was told that it was the thermal sensor and the hard drive. Since the sensor is now on the Apple Obsolete list, I had to purchase it myself and this is the site I found. Shipping took less than a week, and the part was exactly what I needed. I'd definitely buy from here again. Thanks OWC!

Rating: 5/5 This Kit is a Must! June 20, 2018 Just purchased a new iMac 2017 edition and before even turning it on for the first time, used OWC's installation kit to drop in a larger HD and more RAM. This kit and the accompanying video tutorial made it so easy! Couldn't have done it without it. Thank you OWC!

Rating: 5/5 It "just works" June 14, 2018 The 2009 and 2010 iMacs used a hard drive with 'unique' thermal sensing that isn't used on other non-Apple hard drives. This little temp sensor lets you use any ordinary hard drive as a replacement. It installs on the hard drive easily and there have been no compatibility issues with my mid-2010 27" iMac running High Sierra 10.13.5. Mind you, opening the iMac isn't the easiest but with the proper tools and the helpful video on the Other World Computing website it is quite do-able if you are careful. Highly recommended. I just wish Apple hadn't used those weird drives in the first place!

Rating: 5/5 Fantastic Kit May 17, 2018 I bought this and the SSD Drive Adapter, and the process was a breeze. The online video was excellent, and everything needed was provided in the kit. I was concerned about breaking the glass, so I had put this off for some time, but after using this kit and video instruction, I would not hesitate to do it again, or recommend it to someone else.

Thank you very much!

Rating: 5/5 Resurrected 2009 iMac 27” May 11, 2018 My old iMac died 2 years ago. I took it 60 miles to the apple store where I was told they couldn’t do anything for me. So I ordered a new hard drive that appeared to be the same as the original. It didn’t work. So I ordered a new one and a temperature kit from OWC. My original disk that came with the computer would not load. It took me about a month, but I finally got the thing to load from a brand new copy of Snow Leopard. Now I’ve updated to El Capitan and trying to decide whether to go to Sierra or High Sierra. It’s like having a brand new $2000 iMac, interacting with our other iDevices in ways we hadn’t even thought of back in 2009. What a nice surprise!!

Rating: 5/5 Works like magic... March 8, 2018 This product literally saved me thousands. My Mid-2010 iMac's HDD finally died after 7.5 years of use but the rest of the system was fine. This cable, paired with a Seagate Firecuda HDD has brought the system back to life and even faster than before. Easy install when following the MacSales instructional video. (About 40 mins all up for me including dust removal from the accessible fans, motherboard etc.) Thanks team - a lifesaver!
