Hi
I have EVGA 1080ti FTW3 Elite Gaming card. I recently fresh installed windows 10, installed the latest Nvidia driver, installed Precision X1, and noticed something strange.
 
I remember that my card comes with an asynchronous fan control function, where each of the 3 fans is tied to the GPU, Power, and Memory respectively, and fan speeds are controlled asynchronously for each of the 3 fans.
 
I installed the 1.18.0 version and noticed that all three fans are tied to GPU despite my card is ICX capable (see attached image). It used to be that first fan - GPU, second fan - Power, third fan - Memory. I confirmed this by running a GPU stress test and observing that the fan speed % for all three fans are indeed tied to the GPU and change synchronously. All the sensor readings in ICX are normal (10 sensors).
 
I thought maybe this only happens in a newer version of PX1, so I installed the 1.0.7 version (July 2020) which I confirmed in the past that it correctly controlled the fans asynchronously and the problem was still there.
 
Could this be the issue that comes with the newer Nvidia driver? I know cards that are not equipped with ICX have "GPU" written for all their fan but I remember that wasn't the case for my card.
 
Any insight would be very appreciated
 
 

Cool GTX
is the "chain icon" for the fans a "broken link" on the main page of X1 ?

 
Yes, they are broken.
But I think they only control the manual fan sliders - i.e. when you slide one fan, it slides all the other fans together.

Sounds like normal experience for an FTW3 card using Precision

Just an update, I talked to EVGA tech support team and they suspect it's most likely the newer Nvidia driver that's causing this issue.
They said they will keep an eye out for this, but if you are having similar issue as I am, you can try rolling back the driver version to see if it fixes it.

On my 1070ti I use the older Prec. OC ( 6.25 I think?)  as X1 never worked properly with it.....
 
1.1.9 works on my 3080XC  but 1.2 does not ....it won't remember Fan Settings.

X1 (1.1.8) will remember the fan settings for my card - 1080TI FTW3 Elite Gaming - but all three fans are tied to GPU temp instead of being individually controlled by GPU, Power, Memory temp sensors.
 
The problem was still there even when I rolled back the X1 to older versions which I remember to handle fan speed correctly, so it's most likely the Nvidia driver that's causing the issue I think.

I checked my old system 1070ti FTW2, and it has precision XOC 6.2.7 and the fans (GPU + Power) have no issues running at different speeds.

May I ask what Nvidia driver version you are using?

I'm wondering this as well.
 
EVGA RTX 3080ti FTW3 Ultra - Precision 1 installed, have set a custom fan curve, but am confused about the ICX button. I turn ICX on I see my fan curves on the left, the Fan Speed Auto (the chain is connected) and the Auto fans are all at 0%.
 
If I click on ICX, the fan display on the left disappears, as does the Auto Fan Function on the right, so does this mean the fans are now controlled by the ICX sensors?

No , they are still controlled by your Fan Curve , the ICX button ( and sensors) on the 3000 Series appear to show/do little except show the GPU temp
unlike my ICX2 on a 1070Ti which shows memory temps etc as well at 9 different points. ( with shortages everywhere on chips,
maybe EVGA just couldn't get the sensors so they aren't even on the PCB? )
 
with precision x1 1.2.1.0 ( 1.2.0.0 had issue here) with no fan curve and Auto Fan OFF the fans should run at 33% apparently ( since 1.2.0.0).......
but I use the stealth curve myself.
 
 

Thanks!
 
I've got 10 sensor readings on the card - so that part is working correctly. I've got a custom curve, although I like the Stealth curve as well, just using my Custom curve that's worked so well for me previously for now.
 
So even though I've got all these temp readings, I can clearly see that ICX should run the individual fans according to hot-spots the software just isn't functioning right now as advertised? Is there a way to correct this or am I just not doing something correctly? lol
 
Cheers!
