seeing as it runs at 3.4 at stock then 85C at full load is bad. Mine doesn't go above 63C with all cores at 3.6Ghz with the stock cooler (ambient room temp 22C).
It got to 63C in about 20mins and stayed there for the next 40.
I wouldn't go to 4.5Ghz if you hit 85C at 3.4
 
the 85C at 4.4 is because of your voltage, try applying an offset voltage. Mine does 4.3 at 1.1 volts, yours is at 1.248, try bringing it down to 1.15V and see if its stable. You must test for stability whilst reducing voltage if you want to manage temps and have cpu survive.
