Hey all,
 
I've recently started experiencing issues with my 2080ti Black which I've had for about 4 months now. Issue seems to be that the card is hitting a sort of "temp cap" where it's ramping the fan speed to above 100% briefly (3840RPM whereas 3500RPM is 100%). I've noticed most often only on one fan is increasing while the other stays at the set fan speed.
 
I've had the same setup running since I purchased the card but only now has this issue begun occurring. I have had the fan speed capped at ~63% for the majority of the time as it's around the point where I can handle the noise but it is set to increase up to 85% if temps push over 84 degrees, although it has never hit this point and currently doesn't seem to hit this point before pushing the fan speed. The card drops to 1485 MHz Boost Clock before it ramps the fan above 100%. 
 
Some more info on my setup:
Case is an R6 with 2x 140mm Noctua front intake and 1x out rear.
CPU (9700k) sits at 55c under load, air cooled Noctus D15.
No overclocking on the card.
Ambient temp is 22c , I was not experiencing this issue with ambient of 30c during summer 4 months ago.
Test scenario using Heaven, however the same issue is experienced in games as well (Black Desert Online, Path of Exile, Metro Exodus etc).
 
Am I just out of luck here and must let the fan curve push itself up to 85% to keep this card cooled? If this is the situation, does anyone have any suggestions on how to keep this thing cool and quiet at the same time? I would much prefer to be unable to hear the card rather than have peak performance from it. I just find it strange that it seemed to be happy to run on this setup for so long until now.
 

Recent Win 10 update or Nvidia Driver update ?
 
Changes in Nv Control Panel ?
 
What monitor resolution & refresh rate ?
 
Have you cleaned the PC of any dust buildup ?
 
Do a Full Power Off, shutdown, remove power to the PSU (remove cord) - Hold Start button 30 sec, reconnect power

GPU mounted in the PCIe slot or Vertically ?
 
Case fans @ 100% ?
 
Are GPU fans linked together ?
 
Running X1 / what Version number ?

GPU is mounted in the PCIe slot, nothing fancy going on. 
 
Case fans are at 100%
 
The GPU fans are linked as far as I'm aware?

X1 is not installed. 
 
Re JackBauer; I'd agree with you except for the fact it was running perfectly this whole time at 63% fan speed no matter what I threw at it and only recently started doing this. I haven't changed anything on my end as far as I'm aware. It just seems very odd that this issue would pop up now and not previously. And why is only one fan ramping while the other one doesn't? 

I understand the reasons behind throttling and downclocking. I understand that they perform as expected, I am more curious as to why this issue has only occurred recently when I've had the card for a number of months in this setup. 
 
For Metro specifically, I was not able to reach 144 fps, nor was it running with everything on max, but the card was able to underclock itself to the point where it did not need to ramp the fans or crush the framerate at 63% fan speed until a week ago. 

Does it run cooler @1440 & 120 Hz
 
How are you controlling the GPU fans ?
 
Even though you see Max temp of 85C & the Rated Max GPU Temp in C = 89 --> it could be Nvidia Boost 4.0 doing its thing to protect the GPU

Sounds like a similar issue that a few of us had in this thread.

A lot of us though were seeing the fan turbo mode kicking in when reported temp was lower than 85 degrees.
 
85 degrees is the programmed bios safety limit where the fans will run the loud turbo mode. 
 
It just came down to bad TIM that needed replacing.
 
 

I think going with a hybrid kit is a great idea and you won't be disappointed. 
 
Check this link here to hear from others who did the same.

When you say it kept getting hotter and hotter before crashing, what were the temps?

Quick update.
 
Didn't even get a chance to re-apply the thermal solution. I was playing some Path of Exile and I had capped the games frame rate to 150fps and put the card on default fan curve so the card wouldn't need to push so hard and the fans would be quiet. Seemed fine for the past day, not going over 70c. I got home from work today, started playing some Path of Exile again and after 15 minutes the card kept getting hotter and hotter with the fans pushing to 85% and then both fans pushed to 3800rpm and my PC crashed three seconds later.
 
Might be time to consider RMAing the card?

Sounds like you may have a psu issue. What is the make/model/age of your psu?
 

And you're powering the card with two separate pci-e power cables instead of a single pci-e cable that splits into dual 6+2's?
