Building my first PC and I have already installed the motherboard (ASRock Z77 Extreme4) and the CPU (Intel i7-3770K), can I install a Cooler Master Hyper 212 Plus fan on it, or do I have to use the basic Intel fan? Can I use the Intel fan and still over clock?
Yes you can the Hyper 212 Plus has support for 1155, you only need to check it's in the right position. In the instructions you can show how to put it for 1155. Overclocking with Intel fan is not recommended as it can be overclocked 200-300 mhz no more.
