My budget is 80$, I want a air cooler that's not too big, but can handle overclocking a i5 4690k to about 4 Ghz. The Noctua ones are pretty good, but the fans are ugly (I'm going for a black/white color scheme). I've also looked at the BQ Dark Rock 3, not the Pro version, (the Pro wouldn't fit in the S340) and it seems okay, but I'm not sure about the temps. So, what are your suggestions? Could I just get different fans for the Noctuas, go with the Dark Rock 3, or something completely diferrent?
