I've been dealing with overheating issues on my Asus TUF RX 6900 XT since I bought it about a year ago. No matter what I try, it still runs hot. I've repasted the die twice—first with MX-4 and then with MX-6 along with a 12.8W thermal putty. Despite the fans running at over 2500 RPM, the GPU temperature is consistently hitting 91°C, and the hotspot is reaching 110°C. The delta is usually around 15-17°C, which isn't too bad, but I'm still really dissatisfied given the effort I've put in. My attempts at undervolting haven't been stable either. Here are my specs: CPU: i5 13600KF, MOBO: Asus TUF B760M Gaming Plus D4, RAM: 4x8 XPG ST41 3200MHz, CPU Cooler: Thermalright Phantom Spirit SE 120M, PSU: Gigabyte UD1000GM, Case: Cougar MX350 Mesh (temps drop slightly when I open the side panel), Fans: 5x static RGB fans at standard speed. Any advice would be appreciated!

The PTM7950 thermal pad is a game changer for cooling, you should definitely consider trying it out! It can make a significant difference for your GPU's temp issues. I've used it myself and was impressed with the results.
Have you checked if all your fans are functioning properly? Sometimes it's an airflow issue that can cause overheating. Also, it might help to double-check that the thermal putty was applied correctly. That can really affect your temps, too.
Honestly, the 6900 XT is just a hot GPU. I had one that ran hot too, and after repasting with Kryonaut, it helped a bit. You could consider that if you haven't already.
Yeah, I've already spent quite a bit on new pastes and the putty, so I'm a bit hesitant to invest more right now.
If the putty isn't improving your cooling situation at all, maybe you should think about modifying your case for better airflow or adding more fans. Sometimes minor tweaks can help a lot!
I might need to change my case and add better fans since the current ones are stuck at a standard speed.
Yes, all the fans are working, and I've just repasted the card again. I'm a little concerned about whether the MX-6 might be causing some issues, though.
