I believe in your case its going to be the temp sensor thats to blame. At this temp you should be losing coolant and experiencing running issues, so I do not even believe its overheating.
You want a excellent 5 star answer & I would like to be rated the same for providing it. Consider I don't know your skill level & I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies. Try your best to respond with good detail so I can do the same. I normally log in at 3pm and work late. A rating is required. Your rating me, what I type. I am not an employee of this website, nor have control over the fees or the time it took to get a response. If you rate negative or not at all you still paid, but I get nothing. I want you pleased with me and my efforts, so let me know if your experience here has come up short.
So you have a new thermostat, water pump, and flushed system. You replied its not an incorrect reading temp sensor. That means the only thing left to cause high coolant temps is air in the system from a head gasket leak resulting in air pockets which restrict coolant flow.
It does have a heat activated clutch. Whiie the engine off, the fan should not wobble and it should turn with some minimal effort.
