Accelero Extreme Plus too loud at idle

Got a KFA2 Anarchy edition gtx580 today, and just installed it in a new rig. It comes with the aforementioned cooler attached.

Now, I thought this cooler should be close to silent at idle, but it's by far the loudest thing in the whole case. I've checked the RPM in Afterburner and the fan is at 23%, the lowest it can be set. I really don't mind it being louder when gaming, and at 100% it can really shift some air, but if I have to sit at idle listening to this annoying fan it will drive me nuts.

Anyone have any advice on this? Is there any way I can drop the fan lower, or should it not be making this kind of noise at that speed?

I'm really at a loss. Picked lots of parts to keep the noise right down, and this is unexpected.

Thanks.
 
Accelero Extreme should be virtually silent at idle. I attached one to my 4870x2 back in the day and it was unaudible at idle. Even at 100% it was a nice swoosh noise rather than a loud harsh noise.

Probably poor thermal paste I would suspect.
 
I have the same aftermarket cooler and at 25% (which translates to 630 rpm) it is indeed very quiet, quieter than e.g. Samsung F4 5400 rpm HDD - very close to silent especially with case side panel on.

What are the other components you have been comparing it with ? (like what is your second loudest component ?) If you have at least one unsilenced HDD I would expect the HDD to be considerably louder. AXP @ 23% could be even quieter than silenced HDD - not sure as I don't have any HDD silencers (my HDDs are just soft mounted in p182 case)

What is the sound signature of your AXP - like does it sound smooth or does it click, hiss, any other anomaly ? It looks very likely that something is wrong with the fans.
Edit. also lowering the idle speed of the fan probably won't help, e.g. I tried flashing mine to 15% minimum, but it wasn't very stable, like it kept fluctuating the rpms if I set it to minimum so I flashed it to 25% and imo that is as low as almost anyone could ever need.

Well, here's the problem then...

Afterburner is reporting 23% fan, but the tachometer is showing 2700 rpm, which is nothing like the 630 rpm I should be getting. I don't know why that didn't dawn on me earlier, considering my other fans are running nowhere near that speed. It's definitely running too fast.

I'm not sure what to do now... any ideas?

Thanks.

edit: That might actually mean 3x 900 rpm though... I'm not sure. Anyway, xtreme tuner hd has allowed me to drop the fans to 20%, and that's just about killed all but the faintest whisper of the fan. I'll keep mucking about with it and see if I can get it any lower.

Thanks for the input so far :)

hello, i have exactly the same graphics card as you and the same problem, i've just made a profile in afterburner 20% at idle and it still spins at 1700rpm. but it is very annoying. i wanted silence, it annoying during bootup when it makes a lot of noise
the fans seem to run a lot a lot a lot faster than the spec on the arctic cooling website.
if you find a fix please let me know
i'm thinking of buying a shaman or replacing the fans completly.

edit- another solution that i have thought in too attach a line adapter to lower/limit the voltage, i don't know if arctic cooling do them, and i'm not sure what i'm looking for, its not the same connection as the 7v adpaters that comes with noctua fans

I wonder if the 580gtx fan is a more than 12v unit. If the speed of 2700rpm is to believed it would need to be dumping 20v through the fan connector. It's unlikely given that most fans these days are 12v but you never know.
 
These cards actually have two 4 pin headers side by side, both for fans I would presume. Maybe one pumps out less voltage?

I dunno. Right now the fan isn't annoying the heck out of me while I get the rest of the PC sorted out, and I've emailed KAF2 to get their verdict on the situation.

I'll update as info arrives.
 
i have a Accelero Extreme Plus installed on a zotac 580 and i ahve fan speed on 85% (max) and i cant hear the thing!! keeps my card at 30 idle 30-50 ingames it should not be loud
 
Trisp -- Noise is subjective. Having fans at 85% may be quiet for you but for others it most certainly will not be. If you can't hear 3x 92mm fans at 1500rpm+ then either your system is loud or you are deaf to be honest.

Are the fans attached to both headers?

Seems a strange arrangement but I suppose there could be dual fan boards that have independent fans.
 
No, there's only one fan plug, and the other header is unused.

I'm tempted just to try the other header and see what happens, but I'm scared to break anything.
 
I see the two headers in this image but this was the Anarchy 480 GTX version.

How strange. Never seen that before.
 
Just gave the second header a try and it doesn't power the fans at all. GPU-Z reporting fans at 23%, but tachometer correctly reads 0rpm.

Click to expand...

I have all my fans attached to a fan controller and all turned down to the minimum i cant hear my computer with headphones on and its very quite with headphones off. I have had artic gpu coolers a lot of time and they have always been very quiet thats the point i was trying to make seeming as op said his were very very loud aka theres somthing wrong there.
 
there is nothing wrong with the card or cooler so theres no point returning it just cost more money. it just the fans are running too fast, as already stated on the anarchy. i think that might be all the same, ( but please let me know IF they email you back)
i believe its different if you purchased the xtreme plus seperatly, you got a 7v and 12v to 4-pin (not pwm) line adapter with it.

you can't lower the fans speed less than 20% on the anarchy without flashing it which i don't want to do, thats why i thought an in-line adapter to drop the voltage would be the best solution, except i don't know how to do it.
 
You'd need to convert the wiring from the ACXP cooler to standard 4 pin PWM and then back again to graphics card fan header. You can buy the converters on the auction site and they are about 100mm long and black. Pci express PWM or something they are called.

Still I feel that 20% should be 600 rpm or less and pretty quiet as even though a 580 is a hot card it wouldn't need that many revs at idle speed to keep the GPU cool.
 
the cooling's not the problem its 28-32c at idle and in crysis 2 for 2hours+ never goes above 55c.
But at 20% fan speed afterburner reports the fans spinning at about 1800rpm it they are set at 25-30% the fans are between 2000-3000rpm and you can clearly hear them woooosh, everything else in my case is silent hence why i bought this card.
at 100% fan speed they are reported above 5500rpm and loud. That why im scratching my head. when ac website reports 600rpm like you said
i think the found the right cables but it seems more trouble than its worth.
i'm too scared of bricking the card to flash, so i prob just leave it and get a shaman later unless theres another solution but thankyou your help
 
Email Arctic Cooling support and find out from them what is and what is not right for the card. I have found them very helpful in the past!
 
Must be a sensor glitch then as those fans are supposed to max out around 1900rpm, or something similar. Speeds of 5500 are stock cooling blower fan territory or legendary Delta fans speeds. Im beginning to wonder if the fan sensor is picking up 3 signals from the ACXP or is just interpolating the fan speed it expects from a stock. Check the wiring from the fans and check only the one has a sensor wire.

Maybe your rig is so quiet you can pick up 3 fans running at 600rpm.
