My late 2014 iMac needed a new hard disc, so I fitted an SSD and used this, as I understand that it is needed to control the fan speed and I didn't want to try it without and then have to split the screen from the case again to retro-fit it. Having done an extended write to the SSD during cloning and it barely got warm, I wonder if this is really necessary when fitting an SSD rather than a mechanical HDD? Perhaps a cheaper-to-produce model could be made for SSDs that instead of giving OSX an actual temperature reading from the sensor, it simply had a fixed resistor that was the equivalent of '20 degC all is well' to send back to OSX? Although I appreciate that this is a specific OWC connector, the price is quite steep for what it's made of, so three stars instead of five. Anyway, it got the job done and all is well.
Arrived quickly, well packaged, easy to install and works as advertised
