The CPU might be fine. The temps aren't really extreme, but if the loads are right, it's not working very hard. You really need to get temps at full load. Download Prime95 and run it for about an hour to get better temps.
The GPU temps should be fine, but if you want to overclock the cards, you should consider adding a case fan, especially if you have room for one on the side.
I ran prime95 for 5 mins. and I got peaks of 81*C, I stopped it because I was afraid It would fry the thing, should I really run it for an hour? I mean, is it safe to make it run under that amount of heat(or possibly even higher) for an hour?
