This should be the optimal temperature while it's under load, if you believe it's struggling to even cool down at idle consider getting an aftermarket fan or clean the thermal paste with some specific alcohol (?) and apply new paste, look up on YouTube to see how to clean the old thermal paste and apply new one (it's important that you don't put too much on).
However if you really are worried about the temperature, I suggest getting an after-market fan. The stock cooler does it's job well, but getting something like a CM hyper 212 evo would help keep the temperatures lower even under heavy load
Okay so I went on a swedish website called sweclockers where they have the BIGGEST geeks from sweden, and everyone said it should be fine as long as it doesnt go over 80, but they told me i should get a new cooler and replace the thermal paste, so i guess I'll do that
