Such an aggressive fan curve is only made on 1000W and 850W units of the G3 series
550W, 650W and 750W - have a much smoother relaxed curve
I'm curious, what is the fan curve for the 850W unit when the ECO mode is off? It is possible that in this mode it will be much quieter at normal load...[/quotemsg]
That's an interesting thought. I just received it yesterday. On ECO mode, it was silent up to a point, and then due to temperature probably (I was not stress testing anything) the fan revved up very dramatically. It easily became the loudest thing in my computer as it was a REALLY significant increase from baseline.
I'll be working on it for the next several days to decide if it's worth keeping. The tested efficiency in this review is great, but noise is a huge issue. I have it in a Fractal Design R5 specifically to keep that down!
