From my personal experience the Coolermaster 212 Evo is much more quiet than the stock Intel coolers. The fan is really silent even at 12v.
I've tested this against socket AM2+, AM3, 775, 1155 and 2011 stock coolers.
It's also much much better at handling overclocks.
- i5-2500k @ 4.8GHz under 85C. ASRock Z75 Pro3 auto-overclocking. (HAF 912)
- i7-3570k @ 4.3GHz under 63C. ASUS P8Z77-M auto-overclocking too. (Define R3 Mini)
- i7-2600k @ 4.8GHz under 75C. Manually OC'd on my P8P67. (Define XL)
- Phenom X2 555 BE @ 4.2GHz under 60C. Manual OC on M3A32-MVP Deluxe.
I really say go for the CM 212 Evo, it's a damn good cooler for the money.
