Superflower feedback. great PSU, however very louad.

I have a superflower 1300w PSU.

It appears to be rock solid with it's primary task - power delivery.

My system is virtually inaudible, except when the psu decides to turn the fan on under load, the noise is most unpleasant. - It just turbos for a few mins to cool down then silent again, there is nothing in between. Or I can have the fan at max 100% constantly.. That is ridiculously noisy - hairdryer style.

It is much much louder than the sli 980's which give off a unnoticeable very gentle woosh, the superflower sounds like a car speeding off outside.

I Understand the PSU needs to cool it'self if it needs too, however a gentle 30% constant spin on the fan surely would also be very quiet and have a more desirable effect of constantly cooling, negating the need for turbo% 0, turbo%, 0, turbo%.

Does anyone know if the similar EVGA models suffer from the same flaw? Or can enable more sensible fan profiles ?

The motherboard power cables are shorter than average... why ?
The housing doesn't get hot to the touch.
No coil whine or capacitor squealing.
It looks good and feels solidly built.

It's a great PSU for the money, however the fan noise makes it unpleasant to use.

What alternatives are out there which perform as admirably on the power delivery front ?

Yes the Leadex Gold 1300

The Eco mode - as I have set as now, is passive (silent) until a particular load or heat is reached (not sure which determines it), then it gets noisy.

The auto mode is just silly with how noisy it is, a proper leaf blower.

I think the psu would be awesome if you seriously over spec it for your system, however if you go over maybe 50%? under it's ability it's when the issue arises.

I have thought about that, or adding a resistor of sort that could potentially slow it down a bit.

It appears not to be defective of such, just a design flaw, reading external reviews the superflowers psu's are classed as some of the noisiest available. Whilst providing great stable power throughput.

I'd rather not go poking about in places I shouldn't to be honest, I have no idea about the mounting or wiring of the fan, nor the required voltages, I very much doubt its a standard PC type affair. That said superglue is handy stuff
It would void the warranty potentially be quite dangerous too, I expect there are some fat capacitors waiting to give me a nice surprise even if something else is touched.

It maybe better to find a similar performing unit without the noise.
