A fresh have a question about my ASUS 6600XT graphics card.
When I play games, I notice that the GPU core temperature and the junction temperature have more than 20°C difference.
For example, the core might be around 65°C, but the junction temperature goes above 85°C.
Is this normal for the 6600XT?
Will this temperature difference affect the performance or the lifespan of the card? (IMG:[invalid] style_emoticons/default/wink.gif)

Junction temp is the hotspot as it was known on NVIDIA. I think AMD rates it as high as 110°C, while its not optimal that it's this hot, i doubt it will affect the lifespan of this card in a way that matters for the next decade. As for performance, just see if its downclocking or holding a stable boost clock.

It is pretty normal. You could try undervolting to improve temps.

People are mostly worried if tjunction is going over 95oC, as 110oC is the Tjunction limit.

A slight undervolt can usually drop the temps dramatically, and can some times even marginally boost performance.

For the ASUS Radeon RX 6600 XT graphics card, typical temperatures will range from 60°C to 75°C under heavy load, like during gaming or benchmarking. At idle or when not under load, you might see temperatures closer to 30°C to 40°C, depending on ambient temperature and the airflow in your case.

If you're pushing it with intensive tasks, temperatures can sometimes reach 80°C or a bit higher, but it shouldn’t exceed 85°C regularly, as this could indicate an issue with airflow, dust buildup, or cooling efficiency.

I have the PowerColor Red Devil RX 6600 XT and it has similar parameters. ( ºvº)b
