AC condenser/radiator fan not turning on at high engine temps. Noticed when temps get high at idle but go back to normal (190) when driving 40+.

I am using the clutch fan (gktech fan) with shroud and I noticed the ac condenser fan does not turn on at high engine temps ~220. It does not turn on for a bit on start up either.

It works if I turn the AC on though and when jumping the coolant sensor plug. This eliminates "Cooling Fan Control" in the FSM
Also noticed lower radiator hose doesn't feel warm/hot either when temps get high, I assume the thermostat isn't working.

Mishimoto radiator & thermostat, Aisin water pump were put on 3k miles ago. Radiator holds pressure and no leaks. Going to put a NISMO thermostat on as precaution.

Edit:
Lesson learned is don't have your aftermarket temp probe immediately after the coolant line out. Car runs around 170 on AEM gauge. Real temps now!
