I just got a new Raptor X. I have heard that they do make a bit of noise, like a whirring or a hum, but are they supposed to make a lot of noise when loading? Like I can hear the head(?) moving back and forth. Its kinda concerning. I thought a brand new HDD would be silent. I assumed it would make a bit of noise from spinning so fast, but should the arm/head/whatever be so loud? I mean, it isn't quite a clicking, like when the HDD is about to croak (I hope), but it is definitely audible. And this is in my Antec 900 with 3x120mm ACRyan fans, that I would guess have to be at least 35-40Dba, and a Zalman 9500 AM2 which is medium-loud. Any Raptor (X) owners please answer so I know if I need to RMA this thing. Thanks in advance.
