When you have modified the cut-in as low as 92C , you can not get to a cut-out when you are running NORMAL temps.
92C is too low for aux fan in normal climates , but you are in extreme climate, so I assume that is why you have gone that far...You have gone from 105/107 to 92..don't even expect a cut-out. The thermo doesn't even open until 80C.
