This thing is freak'n SWEET. It's a good buy for the money and keeps my CPU (Intel i-7 2700k) running stock (3.50) at a cool 22 c. So far so good, this cooling fan is really quiet as well! Trust me you won't go wrong buying this fan!!!
What's great about it: BIG and CHEAP
What's not so great: Guys when I say this fan is big, make sure your case can handle it.
