The MoBo doesn't OC, the CPU does. Your CPU can very well OC to 4.5GHz, and even beyond that. The 212 EVO is almost an official partner to go with Intel CPUs if you want a budget air cooler. Its less noisy, and does cools superbly. Rarely do I hear any issues of heating with that cooler (or due to that cooler's incapability). Also, its cheaper than the other one you suggested, so I can certainly say you should go with 212 EVO.
I compare EVO's performance with Dark Rock 3 and sometimes even Noctua D14 (its the best one around), which are double and triple the EVO's cost respectively.
