OWC in-Line Digital Thermal Sensor HDD Upgrade Cable for iMac 2009-2010, (OWCDIDIMACHDD09)

The sensor worked as it should. The real fun is installing it. Good luck. It is important to have this sensor in place for the fans to run at proper RPM.

It seems overpriced for what you get in the kit. And I didn't need the tools, just the sensor. But the sensor works exactly as stated. No complaints with how it works.

I found the installation pretty easy, but I work on PCs and servers all the time so I am used to ripping computer equipment apart. There are plenty of videos on youtube that can assist. I believe OWC has a video that helps you go through the process. So a few years ago, like 8, I replaced the HDD on my late 2009 iMac with a 1TB model. If you are looking at this kit you know that only specific model HDD will control the fans on the iMAC. If you don't get a specific model and don't purchase the thermal sensor from OWC you fans will run at full blast 24x7. Back then I purchased the HDD model that was compatible with the iMAC to avoid having the fans run at full blast. I recently moved and the HDD finally failed so I decided to upgrade to a SSD so I purchased this kit along with NewerTech AdaptaDrive 2.5" to 3.5" Drive Converter Bracket and I had the SSD installed in well under 20 min. The NewerTech AdaptaDrive 2.5" to 3.5" Drive Converter Bracket is not needed and you could just use a 2.5 to 3.5 adapter, but the iMAC bracket might not fit right and I think the cables might be too short without that adapter. I purchased it because OWC uses that adapter in the kit they sell on their website so I figured it would make the install easier and quicker. Didn't bother trying with a regular adapter so I am not sure if it would have worked or not. Needless to say this kit works great and comes with all of the tools you need to get the job done. I spent $115 between this kit, the HDD adapter and a 480 GB SSD. Can't really complain considering my iMAC from 2009 runs quicker than some of the PCs at my job that are only 5 years old. As a tip, use a set of tweezers to hold the screws when putting the screws back in that mount the LCD screen to the frame; those magnets are pretty strong.

My old iMac worked great until it didn't. Fantastic... The hard drive failed. They tend to do that. I replaced the HDD with a brand new SSD. But what I didn't realize is that fans will run at full speed when you're replacing a mechanical hard drive that doesn't have the connector for the built in temperature sensor (other HDDs I had didn't have it). They are loud and I didn't want them to get worn. Using this thermal sensor I was able to stick the actual sensor on the SSD and power it with the included SATA connector. Just be careful taking apart and tucking in this connector, I recommend going to iFixit's website to view some suggestions for whatever model you're using this on.

Works well. If you can install a hard drive in an IMac this is easy enough. I feel it's a little more expensive than it should be but you don't have many other options. The only other way to stop hard drive fan from going full speed all the time is to install fan control software and that comes with its own problems.

Worked perfectly with iMac mid-2010 model. Replaced original HDD with Samsung EVO 850 500GV SSD. No fan issue, so this thing did its job. $40 for tiny little thing is excessive, IMO. It should at least include mounting bracket for this price. Use OWC and iFixit YouTube videos for step by step.One recommendation, I found connecting monitor cable back to motherboard when reassembling everything the hardest step, as there wasn’t enough room to insert and lock connector in its place. After several tries and almost damaging connector, I ended up removing the cable from the back of the monitor, then I was able to comfortably connect and secure it on motherboard. Connecting it back to the monitor was super easy afterwards. You may not run into the same but if you do you can avoid damaging connector this way.

I just used this kit to install and SSD on a 2011 iMac which the drive failed on and it was much easier than I thought it would be with this kit. The inclusion of the temperature sensor is a huge bonus.

The in-line thermal sensor worked like a champ. I just had my hard drive die in my 2010 iMac 27". OWC has tutorials on their page as well as on Youtube on how to install a new HDD to your machine. As far as the $40 price tag, well worth it. You don't have to go and research which HDD would work with your machine, the sensor makes it work with all HDD drives and SSD drives. I put a 1.5tb WD GP drive that I had lying around, machine recognized it, used Disk Utilities to format it and check to see if the drive was ok with First Aid. (HDD hasn't been used in a couple of years so i wanted to make sure it worked). Everything checked out fine, back in business.
