Technically, those temps are fine now
I wouldn't be too comfortable with them though.
See if you can buy a better cooler
I recommend the Sunbeam Core Contact freezer
It comes with a full tube of thermal paste, a fan controller, and is a very good cooler for the price even if it didn't come with that stuff
(Before anyone comments about the "loose mounting mechanism", that doesn't apply for AMD. The Core contact freezer uses the stock AMD mounting method)
