Question about be quiet! Pure Rock

Yep, it works perfectly. It also has a great price/performance ratio. However, you should not expect too much cooling power if you want to overclock the CPU. Which I assume is the case since you chose a "K" model.

If you're aiming for the 5 GHz mark, I'd recommend the big brother.

I hope I was able to help you.

Ok if you think so. Thank you very much :)
