I was running HWMonitor and Afterburner while playing Resident Evil 2 to get an idea of CPU and GPU temps. CPU temps are great and GPU seem fine but am more concerned with the GPU fans.
I noticed my GPU temps got between 80-85C and when I looked into my glass side panel on my Fractcal Meshify C (plenty open air flow)- only 1 of the 3 fans were spinning. I have heard that all fans should kick in especially if the card gets to 80C+ or is that not correct?
When I run Precision X1 - all 3 of my fans are detected so that seems fine. Do I need to manually install something for the GPU to use all 3 fans, not sure if I am missing something?
Setting a custom curve didn't seem to fix anything either, in fact no GPU fans were spinning when it got up to 80-85C.

Have you just put all fans on manual and set them to like 50% to see if they kick in?

In X1 I did that and all 3 kicked on just fine. I just don’t want to manually have to adjust anything while gaming.
Is this normal?

Well you will need to set your own fan curve in px1 then the way you want it, they all run on different sensors so they can all run at different speeds though as well. You can switch the bios position to OC on the card and that gives a more aggressive fan curve i believe but still you can set your own custom curve as well. If you set your own curve and they still are not kicking on like they should maybe your temp sensors are bad but if they kick on manually its obvious the fans are in working condition. Also make sure you have the newest firmware in your card by opening px1, then click the little circle in the lower right hand corner by the version number, then click update then in the window, then when the folder opens with firmware click the newest firmware for your card, if you have the 2080ti FTW3 gaming i believe your newest firmware is the E202_F970 file.

Thank you! I will try when I get home and report back.
I am learning this as I go so just a question, shouldn’t all 3 fans be kicking on at 80-85c regardless of setting a custom curve? Or is only 1 of the fans for the GPU?

2080 Ti FTW3 -- you have 3 sensors controlling 1 fan each ..... GPU, Power, RAM so depends on the Temp of that unit for a given fan to run
Afterburner Can Not control the 3 fans
--> Set a manual Fixed Fan speed with X1 - when using Afterburner , chose a Profile number (0-9) then apply & then save - now you can close X1
Gaming try 80% fans & watch your temps - because you set a Fixed fan speed --> balance Temps & Sound quality
It also helps to push your case fans faster to get the heat out of the PC case

Thanks! I will try this— do you have any recommended fixed fan speeds or curves?

Lots of people use curves that ramp up gradually then more aggressively at higher temps. So like 50% until 40C, then 60% at 50C, then 100% at 70C. Or you can have it run a fixed fan speed above a certain temp, say 85% above 40C and just let the GPU temp float (use 50% below 40C). Adjust accordingly for your acceptable noise levels and the cooling effectiveness of your case.

Okay cool this is very helpful! In X1 - I apply the curved fan or fixed fan speed to each fan individually correct?

Yes - however best sound quality by running them the same speed
You Must set each one for a Fixed Speed to be save before closing X1
With a Curve you can set them as Linked (chain link icon closed) if you want to have them "work as one

Absolutely that makes sense. X1 must be open to use this fixed speed or curve right but afterburner can have a profile set to work without having either X1 or Afterburner open? It saves to bios with Afterburner?

Fan control in Precision/Afterburner is strictly software controlled and doesn't write/save anything to the VBIOS..Precision/Afterburner auto fan control (curves) require that Precision/Afterburner be open/running..However, you can apply a fixed/manual fan speed and close Precision/Afterburner and the fixed/manual fan speed will remain.
EVGA iCX series asynchronous fans (like yours) are not supported and will not be supported in future versions of Afterburner..You can only control the GPU fan and not the Power/Memory fans with Afterburner.
You can kind of make auto fan curves behave like manual by double-clicking in the Fan Curve Editor to change it from a curve to steppings..Remove fan setpoints by clicking them and pressing the keyboard Del key..Add setpoints by clicking on the fan speed line..You have to turn on "Fan Curve Control" in the Fan Speed settings to enable auto-fan control in Precision.
Without any software intervention at all, the fans should come on at 65C by default, I believe..The left fan is the GPU fan, the other fans are for Power and Memory..To see the individual component temps, click on the "iCX" buttom at the bottom-right of PX1.
Hope that helps a little more.

Thanks everyone! You have all been a tremendous help.
After setting a custom curve my temps on card barely get over 60-65c with high settings and a tolerable noise level now so I am happy with that!
The only thing is I cannot get X1 OSD to show FPS- it remains 0 and I have updated my firmware. I just use AB to show FPS instead but might create a profile in AB to correlate my fan speeds in X1.

For osd to work you have to enable it in px1 and then px1 has to remain open if I remember right.

thanks for the update, Happy to Help  OSD function in X1 seems to be an issue, your not the first person to mention this not working - several threads about this on the Forums
