Using the stock Intel heatsink? You can do better for as little as $30. Thermaltake and scythe make some good cooling products. I check newegg's open box section for deals, since heatsinks usually have all the clips and accessories included. The motherboards don't. 63c won't hurt the cpu, and is within Intel's specs, but a better heatsink should lower your max to under 60c.
What are you using to measure temps with? Tcase max is around 60-62c for that chip don't remember exactly. Core temp or tjunction max is somewhere around 85c. I'm assuming your measuring core temperatures so I would say your running a bit warm but not too bad overall.
Your running stock fan and stock frequency correct? When was the last time you cleaned the cpu fan and case for dust?
