The temp reading is high. The fans should kick in way before 110-c. Your close to the danger zone of ruining your engine. The first thing to do is replace your thermostat. Then see what kind of results you get. If the fans are kicking in too late then the temp sensor of fan relay is at fault. You should be operating below 90-c on the highway and a little higher in traffic if you have the a/c on.
