What is a normal cpu temperature for a MacBook Pro (13-inch, Late 2011)?
I do not know if iStat works well with Yosemite and delivering correct results.

Your CPU temp is on very high end indicating full load of CPU = continuous load of >100%.

Your SMC reset might not have worked so try it again.

Intel made a simple tool that correctly reports CPU load.

A 2011 model should not have a Thermal paste issue, those usually occur after 5 Years (if), and when the conductive paste dries up. 
But if you consider doing something about it, it is in the difficult category to do it your self.
