First AMD card that I bought, installed yesterday, did some testing. Temperatures seem a bit high for a 3 fan card, I expected better. Are these normal?

Room temperature: 22c, zero rpm off, advanced control disabled, max fan speed 100%, BAR enabled.

With a case panel:

Idle: 47-48c.

Stalker 2 - 94-98% load, 1797 max fan rpm: 78c max gpu temp, 98c hotspot.

Witcher 3 - 97-99% load, 1962 max fan rpm: 80c max gpu temp, 101c hotspot.

Without a case panel:

Idle: 46-47c.

Stalker 2 - 94-98% load, 1609 max fan rpm: 77c max gpu temp, 98c hotspot.

Witcher 3 - 94-98% load, 1684 max fan rpm: 78c max gpu temp, 99c hotspot.

The temperatures you're seeing are on the higher side but not unusual for a high-performance AMD card, especially under heavy load. Hotspot temperatures above 90°C are common for many modern GPUs, and 80°C+ on the core is generally safe, though it’s a bit warmer than ideal. If you're concerned, you could try improving case airflow or adjusting fan curves for better cooling. Just keep an eye on the temps to ensure they don’t go beyond safe limits (usually around 95-100°C for most cards).

I have this exact same model and have discovered that this model has a big issue when it comes to hotspot temperatures.

When the hotspot thermal limit is reached (115 degrees celcius) my PC just shuts down instantly.

However, whatever i tried i couldn't get it under control with software adjustments at all so i decided to dismantle the GPU to see what is going on.

First thing i discovered was that the thermal paste was dried up and the amount was very small, so i repasted it and tried again.

For some time this seemed to worked until the problem returned.

I decided to remove the backplate and noticed that the inside was covered with a plastic sheet that touched the thermal pads, which is obviously not a good thing because the heat has nowhere to go other then heating up underneath the backplate thus overheating the whole PCB !!!

So i removed the backplate and put a small alluminium block with thermal pad on the backside of the gpu and tested it.

The results were remarkable :

- the overall temperatures dropped by 10 degrees celcius !

- the difference between GPU temp. and Hotspot temp. was about 5-7 degrees instead of 20-25 degrees !

BUT, when i tried extreme overclocking i noticed that the clockspeeds were all over the place and again i hit the thermal limit and my system shutted down instantly.

My advise :

- underclock (2400-2500 Mhz)

- undervolt (1150-1175 mV)

- turn off zero-rpm fan

- remove the GPU backplate

- make sure there is airflow for the GPU

In addition i recommend playing games at no higher then 120FPS.

Although the RX 6750 XT is a very strong performer, the out of box settings are surely too much for this card so adjustments are needed for it to run properly.
