How does these fans do in terms of air flow and noise? I am going to be using 2 of them in my P/P on my H50/70, and then another one in my HAF X. So 3 total in my case.

I am using 2 R4's on my cooler master hyper 212(push/pull). The noise to flow rate is decent for the price IMO.

I agree, I own a few R4s i different cases. They arent bad at all. Move a pretty good amount of air and not too noisy. There definitely better out there for more money buts theres also definitely worse. Id recommend them.
