Of course.
That drops the a/c cut-out spec. too low for high ambient conditions.
That is why I recommend anyone using a resistor bridge on the termistor to have it cut-in about 100C... [vs the 105C] ...if you go lower , you think you are doing yourself a favor with early fan activation , but you are not aware that you are also effecting the a/c protection at higher temps b/c it is the same sensor input to N22 that controls comp cut-out saftey.
You are also burdening the fan motors and alternator.

..but I am sure we will hear a different opinion on that..
I have tried all bridging values way before Cool Harness times , and I find the best is to get a 100C cut-in , regardless ...
That will also give you about a 97/98 cut out, Which is fine..without shaving too much off the a/c cut out temp trigger point.
