fan speed shows 25 when set to custom.

Looks like it's hardware locked then, since you did try it the proper way (with having custom + auto enabled at the same time)

Thank You Lays!

 

This was a helpful post, I've got the Gigabyte 970 itx version and the steps worked perfectly.  

I found this post from Linus' video and watched yours too.

 

Idle PC noise is much better now, thanks again.

I tried this on my Inno3D iChill GTX 980 but it hasn't worked I followed the steps and everything worked without any issues but after rebooting the fans remained locked at 33%. Anyone know any fixes?

Someone else had an Inno3d card and it was hardware locked, this may be a growing trend for inno3d cards, they may all be hardware locked.

God that sucks, wishing less and less I got this card.

Followed every step critically step by step and tested the process with the back up version of the bios. Rebooted my computer to a black screen. Tried rebooting over and over while it was still powered on. I had to physical pull the plug out of the wall and turn it back on and it magically came back to normal. When the computer came back up I was normal 1080 resolution and everything looked fine. I opened Afterburner to nothing on the graphs displayed and everything erased, not a single field was filled in. Opened up device manager and found the graphics driver was still disabled so I re-enabled and rebooted. All is well now.

 

Made me realize I am not comfortable bricking my card over a silent fan mode even if it still has the possibility of working.

Yes, I flashed the same Bios.

 

fan curve

 

 

fan speed show Zero when set to auto

 

 

fan speed shows 25 when set to custom.

 

I get the exact same thing with my Gigabyte GTX 970 G1.

As far as I can see from my settings and setting of the fan curve, I have done everything right.

I also notice my fan speeds randomly ramp up, veven though my fan curve is set for them to turn at at around 60-65, it does it at around 45-50.

Do you have user define & auto fan mode on?

Aha, now I do lol.

Another question, is it normal for it to reach around 60c on idle (and by idle, just doing normal web browsing, no gaming)?

ooh, Linus made a video using your guide. Good job and congrats @Lays

The Internet is the first thing that humanity has built that humanity doesn't understand, the largest experiment in anarchy that we have ever had.

It's not working because you don't have user defined fan control enabled.

Click the little gear, and make a fan profile that has the line at zero until 60-65c, then have it ramp up to 40% fan speed.

 

 

 

Thanks but i had tried this initially, at the moment of taking the picture i was experimenting to see if i could get it to work.

Worked just fine on my EVGA GTX 750 ti FTW!

 

EDIT:

 

On manual it just go as low as 25%, but i can set it to 0% in the fan curve.

 

When you're editing the BIOS, you need to set PER11 to 0 as well. Example from my the ROM I flashed to my 750:

wC16Jvc.png

 

I started out with just setting RPM11, PER01 and RPM01 to 0 (as per the guide) and was running into an issue where the motor in the fan on my 750 was clicking and OHM was reporting the fan was running at 32% (though the fan was not actually spinning). So, I dumped the ROM from my EVGA 970 FTW and noticed that PER11 was also set to 0. I made the same change to my 750 ROM and reflashed and the clicking had stopped and the fan speed was reporting 0% at idle.

 

From what I can gather, RPM/TMP/PER11 through 13 are the three fan steps the card will use by default: low, medium and high. I think the motor click was because the RPM value was removed, but the fan percentage (I think that's what its referring to, correct me if I'm wrong) was still set to the stock value.

Hi, im not sure if im the only one having this problem.

 

Ive done everything and it works fine except that once in awhile, like once in 15mins. the fans will spike up to 100% then drop back down to idle. even when the temps are well below 50deg. not sure what is causing this. ive checked the fan curve and everything seems to look fine. other than this minor problem its mostly working well. anyone have any ideas?

You're not the only one :)

If you read previous pages others have this "thing".

@Lays, correct me if i'm wrong, but 100% fan spinning even for only a couple seconds is annoying, i'm wondering if changing the "PER02" and the "RPM02" to about the 50/60% of the max speed may solve this problem.

ie PER02:60% and RPM02:2000rpm.

Someone already here killed his card just about with windows 10 trying to flash it.

 

I would not recommend using anything other than 7 or 8/8.1

Can you post a picture of your Afterburner next to your fan curve?

I'd imagine anything over ~60 watts would make them toasty, but the fans would turn on by then most likely because the GPU core would be warm by then as well.

 

That's a really big IF right there. I feel like you should atleast verify your VRM's are passively cooled and monitor them for an extended period before setting with the 0dB mod.

@Lays awesome quick response , so flashing the thing with a seperated win7 hdd indpendend from the rest of the system should work ? , but do you see any issues running the pre flashed cardwith win 10  ? i thought about returneing the card because of the not 4 GB thing ... but a semi passive 970 must be awesome hope you enjoy yours ... btw: would the bios note if i unplug the fans and use my mobo fan control ?

VRM's from most manufacturers are verified to be able to run at very very extreme temperatures(sometimes as high as 120C), I don't think anything would go wrong.

If there's almost no power going through them, they have no reason to get hot. (As they would have almost no power going through them when you're just idling at the desktop)

Other than the fact that win 10 has very little support for programs as far as I know, it should be ok.
