For myself, I've setup the "Fan Control" freeware

So have I. Use it for case fans. But I would prefer to control card's fans with X1 or Afterburner. Comfortable level of idle RPMs is 800-850 for me. Now I can't.
Hope sw team will change that.

Is a custom curve in X1 buggy or ineffective?  I've never played around with it.  Thanks.

You know, it's also strange even in non-rebar OC bios.
Because X1 provides 3 curves to user: aggressive, quite, stealth. Aggressive has 40% bottom line, quite - 30%, stealth - 20%. But activating of any curse leads to nothing - fans are spinning at 1000 RPM (33%) when idle. Burn of card spins gans to proper RPMs - as it is in the curve, but idle after is also 33% in any case.
It is when afterburner is unloaded or loaded - it doesn't change the behaviour.
Kinda strange curves...
Rebar OC bios differs just of 37% when idle.
 

Yes, it is possible as it is in non-rebar OC bios.
This is the only way out if anyone wants rebar and silent idle on custom curve.
The point of OC bios using is just some RPM out of OS and w/o any additional software.
As I have 450 Watt Normal bios with rebar - so, yes, there is little sense to use OC one.
 
And have to say that on rebar bioses (both normal and OC) fans control through MSAB works more correctly than on non-reber ones.
On non-rebar I have to use some permanent shift of 20-21%. For example, if I need 29% (850 RPM) when idle I have to set 50% in MSAB. So as for higher speeds - I need that gap or shift, whatever.

Hey thanks for the full explanation.  Hopefully EVGA can come up with something to satisfy you guys.
 
I've noticed on my hybrid that the rad fans run low vs. using the MB or case fan hub PWM, by hundreds of RPMS.  They can't hit full speed on the card PWM, but I figured that was intentional because the stock fans are .25 amp, on the card they run about 2500 rpm, actual max is 2900rpm.

Just ou of curiosity: Do you guys still see all the sensors of the card?
When I hit "ICX" in X1, <I only get my GPU temp. HWInfo can't see them either.
 
Edit: Interesting. I changed the driver from 470.25 to 466.11 and both the fan and the sensors work normally again.
470.25 worked fine with a prior version of Windows though.

So this is still not fixed? :(

Just found this thread, after noticing the aux fan connected to my 3080 FTW3 wasn't working—which it presumably hadn't been for a week or two, since I last updated X1.
 
So you're telling me I now need to set a custom fan curve in X1 in order to utilize my aux fan at all? And unless I'm missing something (I may be), it seems like I need to have X1 running at all times for this custom curve to be active? That doesn't seem... great compared to the original behavior.

Is there still no fix for this in 2022 ? I’m having it after flashing the XOC bios just on the OC bios position on the card but with a few caveats. What’s wired is fan one and 2 won’t go under 33% but fan three will listen if I try and make the fans stop in precision. This wouldn’t be a big deal but the fans behave like this if I switch back to normal bios position too that has not been flashed.

My fans stopped spinning. They do a little spin up during boot up. Then stop spinning. I tried in 2 different machines. 3080 works just no fan. 
Seems to me there is no solution for this?
This is bad!!! Will EVGA take it back. I am only 22 days after purchase. Best Buy will not take it back after 15 days.
 

Play games and they still won't spin?

I was wrong they spin. I did not realize how hot it had to get for them to spin.

Must setup a aggressive fan curves in precision x1.

Link the fans to the gpu fan temp curve so all fans run hard to keep those temps down.

Set them to 50% at idel temps to keep the card cooler before it works hard and set them to atleast 75-80+ % when it hits 50c atleast to work hard to keep the temps down in the 60-70c range when gaming.

Fans won't help much if they don't stsrt up till 60c . Hard to control the temps when the card already is in the 80s.

will do! The heads up!

My fan 3 bearing just burnt up out of no where after 3 weeks of use (got the card 3 weeks ago). I decided to remove fans and replace with Noctua fans, and I'm just going to run them 100% of the time. At least I wont have to worry about that bug anymore as well.

Whats interesting is it seems this is happening to other people, Just had the bearings burn up on my 3080 FTW3 Ultra on the middle fan. Looking for replacement fans seems like a group in China knew this was going to happen and is selling OEM fans for EVGA cards at 30-40 USD a pop.
