Hello, wrote to support about this but only got this answer :

Thank you for contacting Technical Support,

and sorry to hear you have issues with Fan of the Graphics card.

Please find one of the Stable BIOS available for this Graphics card.

and let us know the results after updating the BIOS.

Regards

 
Answered that about a week ago and got no answer since then, so i would like to know if anyone who had this issue found a fix because i'm getting tired of my GPU randomly ramping up to VERY loud levels every 10 seconds.
I did try to "find" a stable bios. I got one from here and updated to a seemingly older version (or i most likely just don't understand bios versions), going from 94.02.26.80.70 to 94.02.26.48.68 and that did nothing.
Here is exactly what i wrote to support :
 

My GPU fans keep ramping up and down to REALLY loud levels nearly all the time they are under load, like they are trying to take off.

When i open precision software the indicators are off the charts which signals something is wrong ( look attached image).

looked on the net and your forums and it seems many had this issue which sometimes led to the card dieing so i would like to have your input before that happens (though right now the issue is how annoyingly loud the card gets) or get this one replaced.

Precision software version : v1.1.7
Fimrware : 2.01.18
BIOS version : 94.02.26.80.70
Display driver : 461.40

 

 
Edit : The card is a 3080 ftw ultra

Hi, I Built the computer last december
Case : meshify 2
Mobo : b550 strix f gaming wifi
cpu : ryzen 5600x cooled with arctic liquid freezer II
ram : 16gbx2 trident Z 3600 mhz cl 17
PSU : 750 NZXT
 
I did try to create a custom fan curve and switched between all the presets but nothing changed this behaviour.
As for temps places are still quite cool here in France with my CPU staying at around 52~62 c under load. only the GPU ramps up to 71 or 81 c
Never tried switching the bios switch as i didn't want to play around with higher power limits or any other overclocking tool since the gains when overclocking a 3080 ftw aren't worth the hassle or higher power usage imo.
I don't understand how that could help with the fans ramping up, but i guess i have nothing to lose by trying, i'll keep you posted.

Nothing ? :/ i don't wanna necro old posts just to hear from those who had similar issues

I was hoping to hear from support before going through the hassle but it's been a week since i had any reply to my inquiry so i might as well do so.
I figured as i would be going back and fort with the support we would come to the process of RMA if everything else failed, though at this pace i would have to wait a year before we reach that point it seems

Yes, ran it without precision as i never used the software appart from minor rgb tweaks before all this started.
I've been approved for RMA so i should be getting another one to test soon, might as well keep you guys  posted on the issue.

Helo everyone, got a new 3080 through RMA and things are much better. First of all the fans don't ramp up anymore but i'll test it for a few more days to make sure.
Also the temps are much better, i used to be around 73c~83c but now i hardly go above 72c.

Thank you all, the new card seems to be working without any issues and much cooler than the old one :)

Glad to hear it was sorted. Leaf-blower level fans are never a fun problem to have. More evidence of the good customer service from EVGA at least

Haha had to send it back for RMA

lots of fans problems i hearabout in the 30 series

How quick was the RMA process for you?
