RTX 4080 Super Pro Art OC high Hotspot Temps

[F0RG]

My card is just straight out of the box, with the latest drivers and nothing else. 

I read reviews and most people would claim to have a hotspot in the low 70s. However, mine spikes to up 93°C while gaming - and since of course it's limited to 84°C by default, it starts throtteling at this point. I've also notices that the clock speeds would reach up to 2760/2775Mhz, although the card runs with the standard BIOS and thus should only reach 2610Mhz.

Since I've nothing changed on the card - anyone had a similar experience? Could I try to repaste the card myself you would it void the warranty? Because I don't want to wait two weeks for a replacement.

What even weirder - and probably not connected - I had a similar issue with two seperate RX7900XTX. Both also clocked higher than they should and thus had very high hotspot temps.

Hi @F0RG 

A hot spot of 70c is fairly optimistic. I'm running a TUF OC 4090 on a custom water block with Kryonaught Extreme with a hot spot delta of around 12c, and mine can exceed 70c. What is your temperature delta between the edge temp and hot spot underload?

Please note that the stated boost clock is dynamic and GPU Boost will push the core frequency further based on load, power/voltage limits and thermal conditions.

The hotspot is in the typical range of the 10-25K delta. However, since the hotspot exceeds the cards limit of 84°C, I assume that there is something wrong and the card must be throtteling.

And I also assumed this to be confirmed, as most reviews I read online described a way lower hotspot than what I was experiencing.

The GPU Hotspot is the hottest reported sensor on the die, for which there are many. The hotspot should not exceed 110C, not 84C. 84C is the thermal limit at which GPU Boost will start to throttle the effective boost clock. Whilst it might be possible to improve the hotspot temp through reapplying thermal application in some cases, it's well within tolerance.
