Eco Mode Super Flower/EVGA PSU

maklabouhlel · 10 Apr 2016 at 09:59

Hi. I read a review on here once that the fan runs at full speed with Eco Mode off (Here is the video of it). The manual actually contradicts this. Can anyone who owns these psu's, please confirm whether the fan runs at full speed or is temperature-controlled when Eco Mode is off. Many thanks.

I am pretty sure that with ECO mode set to off the fan just operates as a normal temperature controlled fan. With ECO mode on the fan stays off until a certain load or temp threshold is reached.

I just got refused rma (not OcUK) saying the fan is supposed to be noisy in non-Eco Mode. It appears to run at full speed and is so noisy I can't bear it. I can't afford to run in Eco Mode due to my set up.

I think you have been fobbed off. Scam (Bolton outfit) by any chance? Maybe our EVGA rep will reply tomorrow to confirm things. If he does confirm what I said do a RMA direct with EVGA.

That sounds like a BS excuse to me. I've got two EVGA PSUs and my dad has one. Neither of mine are on eco mode and neither is his. All three are dead quiet. It does depend where the temperature sensor has been glued, but that is not normal behaviour.

Hopefully the EVGA rep here will respond and confirm it's not normal.

You've got me interested now. Mine is also loud with Eco-Mode off, but completely "normal" (i.e. silent) with it on.

My evga and i have the eco mode off- the fan spins dead silent.

FredFlint · 11 Apr 2016 at 12:14

I have two EVGA PSU's, a 650W and a 850W and they are both silent. I also have a 650W Super Flower and that is silent.

550 G2 Owner here. Fan is quiet with eco mode on or off.

Thanks for the input everyone. I know fan noise is subjective but compared to the fan noise in my first post video, how would you say your fan sounds, same or quieter? It's definitely not dead silent as many people claim.

Yeah thats running way too fast, summat wrong there, my g2 fan runs really slowely on normal mode and like pasteymuncher says turns off completely on eco mode.

Im actually gonna replace my fan as its developed a click, but even with the click its way quieter than yours.

BluD, don't invalidate the 10 year warranty because of a fan. If it's that bad do a RMA with EVGA now that it's a UK address.

lamboman · 16 Apr 2016 at 16:45

Just to provide another confirmation (not the OP), now I've checked mine, it also runs almost exactly like this with Eco Mode off. Also has an annoying squeal.

Looks like a potential swap.

Yeah, it might just be a simple repair for them, maybe a fan cable not plugged in properly inside or something, although the cables in mine were all glued in so i cant see them coming loose.

At room temp and idle speed the fan should only be turning just past tickover probably around 600 rpm.

I'm doubtful to be honest, I think it's more likely to be a faulty sensor or voltage regulator. It'd be very difficult for the connector to become loose in transit, and very difficult for it to have been incorrectly connected in the first place.

That said, at full chat this isn't a loud fan. Just shouldn't be so loud or whiny at idle!

i just got an RMA with the above "outfit" for a noisy fan,so must have been something else.
