Not sure what my ambient temp is in my room but I do always have a fan on me at my desk and the computer tower is on a hardwood floor. I'm just worried because I use speedfan to monitor my temps and when the core temp goes above 50c a little fire icon appears next to the temp reading which worries me.
If you are worried I can tell you AMD heatsinks are notorious for being abit.. bad, well not notorious but they're not great, the intels aren't amazing either.
So if you're really concerned you can always replace the heatsink with a nice coolermaster I suggest with the same dimensions as your current heatsink. But you're acceptable temp wise as you know.
