Does anyone have any experience with the Arctic F14 PWM fans? They're cheap, have high CFM, but I'm not sure about their noise. They would go into a Define R4 case, and I would like to know if they're really loud or not.
Also, is there a big difference between the Define R4 and the Define R4 Windowed in noise levels? I really like the window, but if the standard version would be significantly quieter, I could live without it.
And how many fans are overkill? The R4 has 6 (or 7 for the standard version) slots, and I was planning to fill all of them, but I'm not sure if it's worth it.
