Exactly, that's not only too high for your taste, but to my taste as well, I don't like it, but what can I say? since it's stable, I guess it's fine too
I used to open CPU cooling program when i'm not doing things intensive, so the cpu temperature drops down to ~43C
but again, when I have to play 3D games, I have to turn that program off, otherwise it will usually crash.
When I come back from gaming, it goes up to 65C..
I never play a game long like 3 hours, I don't know what would happen if it stays at such high temperature for 3 hours? Reboot?
