GPU overheating.

Hello, everyone!
I just got back to FFXIV after a long time and I'm facing this "hot problem".
My GPU temperature is going high as soon as I enter the game.
In game, I tried all the possible graphic settings, but the temperature stays around 92ºC. In other demanding titles the maximum temperature I recorded was 82ºC.
I'm not using any overclocking.
Fresh Windows 10 installation and AMD drivers are up to date.
FPS fluctuates between 60 to 70 in "High Desktop" 10 less if I go "Maximum", playing in 2560 x 1080 (ultrawide).

Operating System: Windows 10 Pro 64-bit (10.0, Build 18363)
Processor: Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz (8 CPUs), ~3.6GHz
Memory: 24576MB RAM
Card name: Radeon (TM) RX 480 Graphics (XFX GTR Black Edition 8 Gb)
Monitor Model: LG ULTRAWIDE
Native Mode: 2560 x 1080(p) (60.000Hz)
All inside a Corsair Carbide Spec Alpha with 3 fans

Thank you all in advance and Merry Xmas!

Clean the heat sink of the video card with compressed air (like the aerosol can ones) if you haven't already. Dust buildup over time (especially if you have pets or if your PC is on carpet) can cause parts to overheat.

Check to ensure both fans on the RX480 are spinning, as it could be a cooling issue. If I recall that particular card model you have has easily replaceable fans if one happens to be malfunctioning (I believe the XFX hard swap fan kits on amazon are compatible).

If you are using fan curves, make sure that the fans are set to ramp up to at least 70-80% above 75C (if not set to 100% around those temps).

Case fan orientation can have a large effect on GPU temps, if possible have one of your case fans blowing air from the front of the case directed at the GPU to reduce the risk of the card recycling hot air. A positive pressure setup is also usually ideal (with those 3 fans, 2 intake, one exhaust. However, the ideal pressure setup can differ between cases).

If you are confident about electronics disassembly and reassembly: you could try removing the heat sink on the card and reapplying the thermal compound (would need to buy some, like Noctua's NT-H2 or Thermal Grizzly Kryonaut) on the GPU die. Depending on temps, usage, and time the compound can harden and be less efficient at transferring heat to the heat sinks.

Good afternoon and thank you for posting in the Final Fantasy XIV Technical Support Forums.

Outside of recommending to lower any settings, and making sure that the hardware is clean, there is not much I am able to suggest. As the issue you are describing could be a hardware problem, I advise to speak with someone who would be able to look at your PC physically.
