EVGA SuperNova 750 G2 noisy fan

[FunkyFeatures]

Hey

I have had my pc for about a month, and noticed that my PSU gets quite warm when I am gaming, so I turned off eco-mode. When it is not in eco-mode it is louder than my whole system. Even at idle. These are my specs:

 

i7 4790k 1.17v 4.5ghz

Maximus VII Ranger

HyperX Fury 1600mhz cl10 ram

Coolermaster hyper 212 evo

Samsung 840 Evo 250gb SSD

Fractal Design Define R5

MSI GTX 970

EVGA SuperNova 750G2

 

I tried using these plugs that shows how much it pulls from the wall, and at load i draw 300w or so.

 

Why is it much noisier than other fans at 1000rpm? Is it a bad fan?

The it also sounds kind of coilwhiney when the fan is running, but when the fan is in eco mode, it doesn't have that coil whiney noise.

[Gofspar]

Mines quiet at full load.

[flibberdipper]

Weird. My 650G1 is kinda loud (but if you look what I'm running it makes sense). But there's no motor noise, rather it's more of an air woosh. But it's still fairly quiet.

 

Is yours a "woosher" or a "whiner"?

mine is a "whiner".

 

When my fractal design define r5 case fans are running full speed, it does the whoosh. The powersupply fan is whine

Mine is quiet. Try putting it into Eco mode (a switch on the back of the PSU). This will disable the fan until a thermal threshold is reached.

And again, weird. You would think that there wouldn't be such a difference in fans between the two.

[FunkyFeatures]

On eco mode, its no problem. Non-eco mode, whining fan noise. I was thinking of, if I added something in the future, if the fan was going to do the thing again. I loose my warranty in 3 years because the place I bought it from (computersalg.dk) is not on EVGAs recommended vendor list. If I upgrade to anything that will turn on the fan after three years, I am screwed if I find out that it is because the fan is half defect or something.

Yea. I find it really weird. I think it is supposed to spin at 800rpm or something near that, but it is way noisier than any other fan in my pc, even louder than the one with the cooler.

I have a evga supernova 750B and its dead quite. under dual 7950 load, its still very quite and barely puts out any heat out of the back. compared to my old gpu with one 7950, felt like it was going to cause a fire

Just leave it in eco mode. 

[Faceman]

Mine doesn't make noise at all, granted because I leave it in ECO mode so the fans don't spin under a certain temperature.

 

Using your hands or feel as a measurement is never good.  These are components with electricity running through them, they are supposed to be warm.  Mine is warm to the touch.  I would leave it on ECO mode, if it was getting too hot, then the fan will turn on by itself.

[Inehmo]

For some reason G2's lowest RPM for the fan with ECO-mode off is really high. If you have ECO mode on, it will start spinning only when certain load is reached but it will still start with lower RPM than when ECO-mode is off.

 

You can leave it to ECO-mode without any worries though, it's not there just for show, it will work just fine with it.

[FunkyFeatures]

My computer has been randomly rebooting, when playing BF4 for a while and I think it is the powersupply. That is why i would like to have the fan on.

Also for future upgrade, say if I added another 970, it would start at lower rpms, or did I misunderstand?

 

But this still doesn't fix that it is louder than my whole system at 750rpm, and that it whines with the fan. My only problem is the whine sound. The whine sound can be heard everywhere in my room, i can usually only air when I'm close.

The box says it just starts at 55c instead of 45c, while the RPM is 750

Random Reboots? Could be something is overheating or possibly swollen capacitors on the motherboard.

 

What's your CPU temperature on load and do you have any capacitors that look like this?

[Columbo]

I have the 750B nex generation semi modular bronze edition. My fan is whisper quiet. I like the 5 year warranty.

Not the CPU, was the first thing I checked. The GPU should ramp up all the way if it gets close to overheating which it doesn't. The motherboard doesn't have any broken caps afaik, i'll check right now - checked, no one is swollen or broken.

 

I have made a very VERY short video about the thing, just seeing if you can hear it on video. Will upload if you can hear it ASAP.

I rushed it, so sorry if anything is crappy about it. I just wanted to demonstrate the noise. It is not the "woosh" noise, but the whine noise.

 

 

 

It might not sound all that loud, but it is really loud compared to the rest of the system. Just trust me on that, and try to listen for that coil whinish sound.

[Guest]

Does the fan ever spin up when gaming if you leave it in eco mode ? 

 

You sure the noise isn't coming from the graphics card ? I know there have been coil whine issues with a lot of GTX 900 series cards.

[FunkyFeatures]

Definitely not from the graphics card. If i leave eco mode off, it gets unbearable under gaming.

My 970 has some coil whine, but definitely not the same sound that comes from the fan.

[FunkyFeatures]

When i get home i will contact evga to asks some questions, it seems like it makes too much noise compared to other people with the same powersupply.

 

edit:
support told me that they would just rma as it sounds like a bad powersupply, now I am going through that. Wonder for how long. Any RECENT experiences with EVGA in europe from you guys? Heard old RMA was insanely bad, but heard they greatly improved the last year or so.
