Yea, you are nowhere near thermal shutdown, not at a gpu throttling point, and low enough that you won't be significantly harming other components. I wouldn't even bother with a respaste (did one on the 660m in my G46 and max temps went from ~83 to ~79).
Point being, yeah, those temps are normal. If you really want them lower, lose the oc or try repasting and replacing the fans. Personally, looks good to me as is.
