GPU Fan pinning to 100% once I hit 83 C

[Aidan Hartline]

So when I am in game or anything of that sort, my GPU fan will ramp up to 100 percent once I hit around 83 to 84 degrees Celsius despite my fan curves telling it not to ever hit 100 percent. When I first looked into this issue with my RX 5700 XT most said it was a botched fan header or something along those lines. So I got rid of it and upgrade to a Gigabyte RTX 2080 OC. However, I still run into the same problem at around 84 degrees Celsius when in game. one of my more temporary solutions was just to drop the core clock to around 1500 instead of 1850 boost, so that the temps never pass 80 degrees and hover around 78 max. What concerns me is that this issue has persisted across 2 seperate cards from separate manufacturers and different architectures and types. Has anyone else had this problem or know the fix?

How are you trying to limit the fan speed? If you are using something else, try using MSI Afterburner to adjust the fan curve.

There may be a configuration in the driver that, despite your fan curves, full guns the fans if it goes above 80C.

 

Even if you could fix this issue, it's not that great of an idea to be running consistently above 75C. You might want to invest in some case fans.

83°C is the default max allowable temperature for an RTX 2080. It makes sense that the fans would ramp up at that point. You should also expect your clock speeds to suffer greatly. Do as @Voxany says and improve the airflow in your case.

Im currently running 3 case fans (2 intake 1 exhaust), which are the Corsair AF 120's. It seems to be ignoring my fan curve however. I have the max temp limit at 88C in MSI Afterburner and the fan curve adjusted but it seems to ignore it. However, I seemed to have some luck in Aorus and when I adjusted my fan curve and it worked the other day but had less luck today. I dropped my Core Clock to compensate and drop temps as well as my power limit. I am probally going to do a full system reset eventually to clean up my PC and run on either MSI Afterburner or Aorus Exclusively to avoid any cross over on commands.
