Hello! Yes the stock intel cooler can get quite loud, you can get a lot less noise with something like a CM Hyper 212 Evo.
By the way, why are you buying a Z87 motherboard and a non K series CPU?
Could you please sugest a better Motherboard. (this is my first build)
The motherboard is great! But you should get a 4570K to actually take advantage of it's overclocking features. If you don't want that then just stick to an H87 motherboard.
