Hello,
i just bought an HX850 to replace an old AX1200. The AX1200 got really loud and was just out of warranty. Instead of replacing the fan I just wanted to buy a new quiet one.
I found the HX850 and thought "Great! Passive mode for low consumption, must be so quiet!". Ordered it, replace the old PSU and turned the system on. What. is. going. on. This one is even louder than the broken AX1200, just by the coil whine. Is this supposed to be this way or did I get a particularly bad one?

It sounds like a seeking hard drive, but there is none in my system.
