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.
 
I wouldn't go around touching the components inside, as you said it'll void the warranty
I'd try and get an RMA, I don't think these are supposed to be quite that noisy? Then perhaps if the replacement is not to your liking, try another brand of PSU perhaps, but these are supposed to be decently quiet at the least
 
Maybe get a video up so we can judge the noise, it could be a faulty fan. How have you got it mounted aswell? If the intake is sucking in air through the case intake grill/fan filter that will add noise.

I too prefer a constant slow spinning fan over one that starts and stops. You don't get heat buildup and if it does have to speed up it doesn't have to do so as much. You end up with a quieter cooler running system. Sadly though this doesn't seem to exist, their relying on the fanless mode for the quiet element and making you put up with a noisier than needs to be fan when it has to kick in. There is definitely room for improvement in this area, one of the few areas left that can be improved these days.
