the fan temp change alone did that then.... the thermostat does not change the max temp the engine will run at, only what it will regulate the coolant down to.

mine will sit at an idle for 30 minutes and never rise above ~205 in 60* weather. my fan #1 is set to engage at 210 and fan 2 at 215. with 204,xxx miles on it and many of them have been neglected at that(especially the cooling system, where i think i'm running on nearly 10 year old antifreeze), i haven't seen fan #2 come on even idling in the summer. fan #1 is a rare occurence even.
