My specs are:
Z77X UD3H Bios F18
8gb 2133Mhz RAM
Mountain Lion 10.8.3
The drive in question is a 750gb WD Black formated to exFAT. It's smart status shows me it's in great conditions, but every now and then when I boot up OS X tells me the drive needs repair.
I already tried...
I found the pump is the loudest component. I can't hear the fans until they go above 1,400RPMs on a Define R4.
I kinda want to buy a Noctua D14 just to test noise levels, since I don't really have a crazy overclock on my 3570k.
