How to control fan speed in macOS Sierra?
I am a firm believer in avoiding software "hacks" to fix hardware issues.  To fix this problem, you need the sensor.  Unfortunately, as you have found out, your SSD doesn't support this connection.

However, OWC makes an digital inline temperature sensor.  Basically, it goes between the SATA power cable and the SATA power connector of your HDD/SSD.  The temp sensor goes on your drive.

The best part about this is that it's a "once-and-done" solution meaning future OS upgrades won't be susceptible to software incompatibility problems like you are experiencing now.



C|Net did an article on this exact problem and a review of this solution.
