I know this may sound crazy, but with your system being watercooled, higher end gpu overclocked, and several hd' etc etc you may find that PSU does not provide a stable 12V rail.

I am not sure of this, but it would be worth testing with a multimeter i think. You have 4 12V rails rated at 18A, hoever 12V +2 is dedicated for the CPU, leaving only 3 12V rails to power the rest of your system - which is not a low powered system.

Can you purchase a cheap multimeter or borrow a quality PSU (750W approx)?
