GPU ignoring custom fan curve and revving loudly at 70c+

[ʙᴜɴ.ᴇ]

hey guys, not sure whats going on here, I've had this issue for a while but recently tried to rectify it by installing MSI afterburner and setting a custom fan curve to stop this random revving to 3400 RPM on my GPU fans whenever the temps reach 70c.

turns out the GPU is completely ignoring the settings and doing the revving still, MSI Afterburner shows the fan speeds match what I set at the time the revving happens yet these speeds only turn up around 2100 RPM not the 3400 RPM I am getting which makes me wonder why the GPU is ignoring what I set and how I can fix this because its really annoying having to play when the PC is doing this.

this is what happens when it starts, just random peaks of 3400 RPM during anytime the temp his around 70c

But sometimes it gets a bit carried away and does it consistently, as you can see it doesnt match the fan curve or what MSI Afterburner is reporting for fan speed, it also appears to be only on GPU fan 1 and fan 2 seems to follow the fan curve. Computer is not overclocked btw.

now I am a total noob at this, I hope my GPU is not faulty or anything, I need to know what is going on and what can be done to fix it, any help will do.

What model of 2080 ti you have? GPU can override custom fans settings when reaching high temps like 85 or 90c, not 70c. Maybe a driver or vbios issue, did you have this problem before or just now?

its a ROG one.

its been happening for a while ever since ambient room temp has been high enough to reach 70c+ when playing certain games.

I found a video which shows the same thing that my card does. starting at 1:25

I still need help with this since its very easy to get to 70c i can't play a single game even remotely demanding without this happening.

set the cpu fan curve in bios

My 2080ti fan liked to rev up a lot sooner than I wanted, too. mine's an EVGA tho, and I used Precision to set it to a custom "Quiet" mode (max 50 fan speed) - thus it's normally quiet - but still liked to get louder sooner than I want when stressed. Wasn't like yours or the video (super loud) but still more than needed vs. temp.

Thus during gaming I manually turn the fan speed of all fans/sync to just under where it sounds noisy (a bit under 50). For some reason this has kept it from becoming loud under gaming stress. I have no idea why it likes to ignore "curve settings" but is fine with manually setting a constant fan speed instead - where manual fan setting is no higher than the max of the curve, anyway.

set the cpu fan curve in bios

is this overriding the msi afterburner settings?

I'm not sure how to do anything in bios im always scared of breaking something in there.

[CatPerson]

I would be curious how CPU fan curve would affect GPU fan curve, bios or not.
Not saying it wouldn't, because I don't know. Am honestly wondering how that works.

^ After a google, maybe that was a typo they made.

oops, misread cpu

it the gpu has a custom bios it may not obey fan settings from software

Had a similar problem after a windows update, after freaking out a bit from the high gpu temps I completely removed afterburner and RTSS, fresh reinstall with new profile and resetting the fan profile to the way it was fixed it all up.

Your fan hits a 100% at 90c and thats too late because the card is already hot and the fan is not cooling it.

At 50c you should hit 50%, 70c is ok, at 80c you should hit 100%. the idea is to stop the card from cooking not to try and cool it when it cooks. The gpu is saving itself because AB is not helping.

do you suggest I change the fan to 100% at 80c?

I have never reached 80c so i dont know, highest I got was 72c and I've been following my temps with speccy, hwmonitor and now msi afterburner for a while ever since the revving started.

the temperature stays stable at around 70c with 2200rpm or so thats what it tells me, just i dont know why it does the revving to 3400rpm because it doesnt seem to make a difference on what temp it is reporting, it doesnt go down at all when it revs.

[Illusion of Progress]

Sometimes, noise variance can be more disturbing than what might be a higher than wanted but consistent noise level. Have you tried setting a minimum fan level higher to see what doesn't bother you? Maybe having it spike it spike up less will be less bothersome.

Any update on this? I have the same problem

check the case cable management
if a gpu fan is stopped, the rest of the fans will ramp up to 100% and not turn down
