About 2 months ago I installed two SSD's in two computers. A Samsung Evo 500gb in an iMac 21 inch and a Samsung Evo 1 TB in an iMac 27 inch. For both computers we installed the Macs Fan Control app in which the SSD's were recognised as a Samsung SSD. We could set that the internal sensor of the SSD was used to control the fan speed. This worked really well until recently.
The Mac Fan Control for the 1 TB SSD still works fine. However, the Macs Fan Control app does not identify the 500 gb SSD anymore. The app does see that the SSD is there, but does not see it is a Samsung SSD with a heat sensor built in. As a result the fan is blowing at 5.500 rpm. I did see on your website a page which says that for SSD's the RPM should be set manually. But I do no understand why a couple of weeks ago all worked fine and now it does not work fine anymore. And on the other computer it still works fine. I would rather use the internal heat sensor because I know with heavy converting the fans RPM goes up.
I have uninstalled, restarted the computer and reinstalled the app. That did not help. I have now set the fan to 1.500 rpm manually because the noise was driving me crazy
I have included some technical information below. Can you please let me know what I can do so that the Macs Fan Control will recognise the Samsung SSD again for what it is and I can use the internal fan of the SSD. Macs Fan Control 1.2.1
