Chasing this cooling issue for months

I'd like a nice little louvre system like miniblinds that I could open or close from the drivers seat and I could make it, but I'm not really sure it'd be worth it time wise.
(speedo type cable run to the front with a worm gear setup on the end to open and close it, and a knob under the dash)

I'll probably just cover a third of the radiator during this time of year and let the electric fan run a bit more.

That whole thing about having full coolant flow in the radiator at 175 with a 195 thermostat just messes with me.

We have had bad thermoststs bad right out of the box but since nothing changed when you put in a new one I would think that would rule that out.
Get an infrared therometer and see what readings it gives you. You can readings on hoses, thermostat, water pump and anywhere else you want. I have chased down a lot of problems with it.
