Summary: Like the other two reviews, the fan goes mental if put a tiny bit of load on it. With no graphics card, it still happened once when I was encoding. With the graphics card, even playing minecraft sends the PSU fan into overdrive. It's too loud to deal with to be perfectly honest and worst of all it doesn't go back to normal speed after when the pc is idle. Another thing to note is that even the normal speed is on the loud side.
