Hello all, wondering if anyone can help me out.  Picked up a kingpin 2080ti and installed it in my case to collect and confirm some initial results.  I removed the evga fans and hooked them up to a couple EK vardar 2200rpm fans on the cards fan splitter.  While in PX1 I am requesting 100% fan speed manually from both fan control's.  the cards vrm fan speeds up, hits 100% and remains consistent.  If I request 100% from my radiator fan header the fans ramp up to 2200rpm, then slow down to around 1700, then ramp back up to 2200 over and over.  Its just ramping up and down in a constant cycle.  Its almost as some sort of internal fan speed control on the card is fighting my manual request.  Before I pull everything from my case and start trying different fans I just decided to ask here first.  I did call evga and they were no help at all.  They basically just responded by saying ok, we will make a note of it.  I'm set on the OC bios, PX1 v1.0.2. along with firmware 2b.fa.42. Nvidia driver version is 441.42.
 
If  you have any insight , please help me out.  tia.

When you write that the fans are plugged into the cards fan splitter, do you mean the cables the AIO fans normally plug into? 
 
You can try plugging them into the 4-pin header by the PCIe connectors. Will require a splitter (Y-Cable) to connect two. 

Well I know it will suck but the obvious would be to test it with the original fans first. If it does it with them you now know it's either a problem with the fan controller on the card or px1. If it's fine at 100% then the new fans might not be getting enough wattage from the controller.

Could just plug in the fans to a fan port on the mb and set it to 100% if it's not too loud or 75%.

Though that's not a total fix cause If their is a problem with the card evga should be replacing the card.

I'd be no help as my card is on a hydro block... and long ago I used 4 Corsair SP120 HP fans on the stock rad right off the bat connected to the mb at 100% the whole time.

Maybe just need to change fan hysteresis to say 3 - 5
 
default is 0 & can allow the fans to hunt
 
Or does this happen at a Fix RPM - say 60%

Hello everyone, thank you so much for the information. I had the time this morning to dig into everything and recable manage everything.  So I hooked up the evga fans and they are stable and functioning perfectly at 100% requested fan speed.  everything is working as intended so long as I use the EVGA fans.  I decided against using them because you can see through the front of my case and my EK fans have gray blades so I wanted everything to match looking in.  So I compromised and ran my EK fans in the front viewing of the case and hooked them up to my MB channel as regular chassis fans in push config, then I hooked up the EVGA fans to the other side of the rad in pull config and hooked them up to the card.  The nice thing is as a result the card is running a bit cooler at stable 2160 mhz clock/8000mhz on the memory (these are just some conservative numbers I am using for regular task usage) with the highest temp just touching 41C.  although it mostly hung out at 39C to 41C.  I'm actually very happy with that number as its actually about 5C lower temp than my other PC which is running an open loop with 2 360mm rads.
 
Like someone mentioned about , because the original fans I was attempting to use ran at 2200-2300 rpm, it appeared to cause the evga fan controller to keep trying to bring the speed down to 1700/1800 rpm, then it would bounce back up to 2300.  I did not have a chance to test anything on the external fan header of the card, but I will try that next when I get some time. 
 
Thankfully everything is working as intended at the moment,  I did not want to rma the card as I just figured its something on the software end.  My next solution was going to be to connect the radiator fans to the MB and just control them through there at a single speed.  I cannot find any software sensors that can pick up the water temp on from the VGA as i'm assuming PX1 is monitoring it ?  correct ?

Does anyone know what GPU2 temp is referring to in the PX1 hardware monitor ?
 

GPU2 temp is kinda of just the temp on the outer part of the die as what i can tell, the GPU1 is the die itself and GPU2 is the outer area of the die.

If you hook your higher rpm fans up to the external header they will work properly, my noctua 3000 rpm fans with a y splittter on them will go to max speeds on that header, but if hooked to the connection that the original fans are on they will not go to max speeds.  Fan 1 in PX1 is VRM fan, Fan 2 in PX1 is radiator fans, Fan 3 in PX1 is the external connection.

oh thats a great idea.  I'm going to do that.  thanks again.  its good to know it wasnt just an isolated issue I was seeing. So running faster fans kind of confuses the cards intended fan/rad header, but the Fan 3 header has no issue accepting fans that run at a different rpm.  I would imagine this is something that EVGA can sort out through the cards firmware ?  Have other people notified them of this ?  Ive never had an aio care what speed fan I installed on it compared to the originally intended one it shipped with.

No idea.. I've never had a px or px1 crash ever. I always need to go into safe mode to delete all the evga's folders in win10. Maybe you removed too much from the register and need to now ddu the nvidia drivers in safe mode and install the drivers again. If so.. do px1 install after.

You did ALL of these steps ? 

Visual C++ Runtime Redistributable is Up to date ?

How Do I Troubleshoot Precision X1 Issues?
 
Did You install with:
Offline to prevent any kind of AUTO Update feature from Win 10 or other software ?
All background software turned Off - Including Security Software [Go offline first] ?
As Admin with Elevated privileges ?

No I did my method of uninstalling the app, removing from registry, then deleting all folders with EVGA.   This time is appears to have fixed the crashing problem (i'm almost afraid to jinx myself and say this).  But I will go ahead and make note of your method and use it in the future.  Thank you.  Luckily with the help in this thread I was able to workaround all my issues and run the card how I want.  I have never had an issue with changing fans on an aio setup to different ones.  but again, I was able to workaround it by using the extra fan header and using fans of the same RPM that EVGA provides on the cooler.  Luckily EK vardar offers 1800 as well as 2200rpm fans.
