Heya, I have had similar temperatures as well, and ye, they are kinda high but if you dont get over 95°C you should be fine. But anyway, if you want lower temps you can undervolt your CPU/reduce multipliers when 3/4 cores are active and download custom fan profile. You can find guide about how to do all this on these forums, just search a bit. This is my current GW2 temp after doing these steps - https://www.youtube.com/watch?v=QKPVbdzUNho
