Don't worry about your RAM temperatures unless you either:
1. You enjoy boosting RAM speeds and push it well past its rated rate (or if your clocks and settings are unusually quick).
2. Your case is terrible—poor ventilation and a cluttered setup making things hot.
I own an H500P with excellent cooling, so I think I'm in good shape and don't need to overclock.
