i5-4690K overclocked temps?

[KoopaCreeper]

I apologize for the newbie question because I've never overclocked before. I have an i5-4690K overclocked to 4.4GHz and cooled by an Enermax ETS-T40-TB cooler. While gaming, it goes up to 65 degrees Celsius. While doing stress benchmarks (Cinebench R15) it spikes at 72 degrees Celsius. Are these high temperatures a problem? It idles at 20-25 degrees, so I'm not worried about that.
