My temp is the same as yours. I've only had the sluggish acceleraton happen when I'm rolling in first and and punch it then let off and immediately punch it again. The car accelerates then nothing, then a split second later the sc kicks in and your gone to 100 way to quick and smooth. I think it's the SC clutch kicking in. My fan does come on very quick and very often. I'm in AZ so we are warmer.
