It seems as though Solid State Hard drives are not consistent in the location they report the drive temperatures. I am wondering if you could create a custom lookup field to be able to pull the correct temperature? Currently Macs Fan Control 1.0.4 identifies the hard drive correctly but shows a temperature of 0 degrees.

I have the Samsung SSD 840 PRO Series and S.M.A.R.T reporter and it currently shows 41 degrees and is located in this field:
190 Airflow_Temperature_Cel 0x0032 059 045 000 Old_age Always - 41


Here is the raw data that is pulled from:

Yes MFC checks for 194 value of SMART
This can be improved, will provide you with a testing build soon
