Even with the fan trick it would still overheat. Hollowing out my old thermostat fixed my short sprints that I have to do around town so I don't have to worry overheating. If I locked the fans it wouldn't make much of a difference in my short runs around town, and wouldn't hold up to me going down the hill.
2 miles at 6 percent grade is steep, and not surprising to cause higher temperatures.

I think dual fans would definitely help on hills, which have lower coolant flow due to lower rpm's. I might use that trick, provided I can keep below 206 at all other times, and can figure out how to do it. This would cause a drain on the mpg but would definitely keep the engine cooler. Another thing I've not tried yet is to go in 3rd gear and go slower.
