Accelero Extreme Plus too loud at idle

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

I've looking into flashing the bios, and it seems easy enough to lower the minimum speed to 5%, which should make it completely silent. Fermi bios editor looks very easy to use, and I can only see problems if there's messing about with voltages or clock speeds in the bios. Safer to use Afterburner for that anyway, and then I could use a custom fan profile in Afterburner to start at 5% and increase the fan as temps rise.

I'm waiting till KFA2 get back to me after the weekend (hopefully), before I take anything on though.

I'll keep you posted.

edit: I'll also add that even with the fans turned off, the card never went above 34 degrees at idle for me, and that's with all the case fans off just now in a closed case while I was trying to get to the root of the noise. So there's no reason for these fans to be running so fast that you can hear them to keep this card cool at idle.

edit2: Contacted Arctic Cooling too

Well, drunken curiosity got the better of me and I modded the bios.

Got the minimum fan setting down to 5% as planned, and they are running just fine, and utterly silent. Idle temps settled at 30 degrees, but now the sensors report 0rpm (fans are spinning, I've checked).

Still don't really know what the cause of the issue is here, but the problem is manageable now. A decent Afterburner fan profile should take care of the rest, but I'll need to work that out once I've got some games on the go.

Bios modding was a piece of cake. If any of you want the modded version just let me know.

Cheers.
 
cheers, i will definatly try when i have time. Probably looks more complicated than it is.
What did you change. I assume the only part of the bios you modfied was the min % you could the change the fan speed to. Lower than 20%
Thanks for your help
 
Modified the minimum speed and nothing else. I'd rather do anything else with Afterburner where mistakes are permanently burned into the card.
 
As it turns out this is largely a waste if time if you plan on using a software overclock, as any software settings will override the bios mod and reset the minumum fan speed to 20%. I had to go a step further and actually mod the bios with the OC settings. Thankfully though, the auto fan now drops down to 15% without any custom profile at idle, and that's more or less silent. Max temps at load have topped around 60 degrees with 40% fan at 900MHz, and that's not really noticable above the noise of my television, and definitely not noticable when gaming.

Still no word back from KFA2 or Arctic Cooling. Great service.

Still not a word from KFA2 or AC.

Seem to be having some software issues that randomly cause the drivers to ignore the updated bios settings, so I finally bit the bullet and just fitted a resistor to the red wire on the fan cable, and voila, this fan now appears to be operating as it should out of the box.

It used to make a racket until the software kicked in to control the fan, but now it's silent from the moment the PC is turned on, and it runs as quietly as it did with my modded fan settings.

Dunno enough about the AEP to know if it comes with a voltage limiter as standard. If it does, it's a massive oversight by KFA2 to not be fitting them on these cards.

I've tried all over to find an extension cable for the fan so that I wouldn't have to void my warranty, and I even tried removing the wire from another mini fan plug so that I wouldn't need to cut the card's wires, but the crimp bit wouldn't fit inside the plug for some reason, and I don't have the toosl to muck about with it. If you still want to try making your own cable without voiding your warranty, the plugs your are looking for are JST PHR-4.

Cheers.

Hi

Sorry to bring up an older thread but I have bought a kfa2 with the same accelero cooler (the gtx 480 pictured above) and have the exact same problem. At 100% it runs at 3000rpm and at 30% it runs at 2,300rpm which is far from quiet.

Did you solve the problem?

I'd really appreciate any help in getting it to work properly. It is by far the loudest part of my computer now, much louder than the 4870 stock fan card that it replaced.

Lucky me I haven't purchased this card then. I'm pretty sensitive to background noise.

Driving me nuts because I am also. I'm not sure what adapter wire I'd need to plug it in to the fan controller on my pc, I'm hoping there is a solution to be found that would not affect warranty.

It got reviewed as nearly inaudible at 30%. I think if the fan actually ran at 30% it would be, but not when it says 30% but still runs at over 2,000rpm.
 
I have recently purchased this card and have the same problem too. At 30% it still runs at 2100rpm and manages to be significantly louder than an Arctic Freezer Pro 7, 2x120mm fans, a 250mm side fan, and 2 HDDs put together.

I have also emailed KFA2 in the hope that they will give us an answer. I'd rather avoid having to flash the bios just to turn the fan down speed down, but it is very annoying and loud enough for people in Skype to ask "What's that noise?".
 
Coming from a Palit dual fan GTX470 the KFA2 480 which I received this week is totally tolerable for me, and a positive factor is that it doesn't get any louder under load. I just find it weird that they have it running such high rpm stock (45%/2500) when even at 30% pwm it still runs incredibly cool for a 480 (56c max furmark 68c max occt here).
 
The guys at KFA emailed me back saying it should be quiet due to the cooler and that I could arrange an RMA for him to check it out. Problem with that is the card itself is not actually faulty.... the fans just run really fast.

I've read you can mod the bios to change the speed down but have no experience doing things like that and don't want to risk damaging it by doing something stupid.

The card itself uses a really small 4 pin plug for the fans, any idea what adapter would be needed to hook that up to a fan controller that uses standard 3pin connections?
 
I'm not sure whether it is just us being fussy... The Guru 3D review says that 2450rpm at 45% is correct, which is what mine does. Either the speed isn't dropping off as fast as it should, there is a problem with the cooler/fans, or it is just down to subjectivity.

I didn't have the guts to flash my 580 but i would love to know how you done the above. I assume it would be the same as just fitting a voltage resister to any other fan and that the fan speed would just be limited and would be shown correctly in msi afterburner. You stated that would need a JST PHR-4 plug.

If you could explain in more detail or show me how you done it i would be very grateful. thankyou
 
Sorry, not read this for a while.

I didn't bother trying to make cables to do this without cutting any wire on the accelero, so I can't help further on that.

Personally, I used an old Zalman voltage adapter that I had lying around that looks something like this

Take the resistor off the voltage adapter, cut the red wire on the accelero, and splice the resistor onto the wire. As easy as that, but your warranty would be invalidated unfortunately.
