The three projects I had were 1)head gasket/LIM gasket, 2)P0401 code and 3)Fan operation.
I decided to fix #1 and #2 and then try and figure out #3 when the car was drivable. After the fix, the temps have not gotten above ~halfway on the temperature gauge, so until now, I forgot about it. I will say that from recollection that the temp gauge only gets to halfway while idling for a period of time (fast food drivethrough). Either the fan is now operating, or I'm getting enough cooling by radiation. I might check into this this weekend. If I find something, I'll let you know.

That's basically exactly what I had. We had 5 o'clock traffic yesterday and after being stuck in that, the temp got past the 3/4 mark - I may just have more air in the system to get out. I'm going to mess with that tonight. I've seen that this model can be a pain with air from time to time.
Ya, let me know what you do with the rad fans - nothing is checking out wrong, but long stop lights or stop and go traffic are seem to be the only effector right now. Thank god! That LIMG took care of a lot.

I still haven't noticed a particular temperature causing my fans to come on or not. That's why I've been looking into all this. The fans run fun on AC but don't seem to run during long idle periods. I've already seen posts advising to stay away from the lower temp T-Stats. Can't remember their exact explanation but it was a point made a couple of times. SO the Switch is located where? are you referring to the ECT? I've replaced the ECT Sensor right behind the T-stat. Which/location SWITCH are you talking about?
