Question GPU is overheating ?

[Alone_Boy_]

About 3 months ago I bought a brand new ASUS RTX 4070 Ti Super Dual.
When I first bought this graphics card, the temperature was 74 degrees under full load and the fan speed was around 55%, but recently the graphics card temperature and fan speed started to increase gradually. In the last benchmark test I did, the temperature was 80 degrees and the fan speed was around 88%.

The interesting thing is that I had the same problem with my previous Sapphire RX 6800 XT graphics card. The graphics card, which initially worked at 75 degrees, later saw 88-90 degrees and started to cause a thermal bottleneck. Now my new graphics card is also gradually going in that direction.

What do you think could be the source of the problem?

My Rig:

Motherboard - ASUS ROG STRIX B550F Gaming.
Processor - AMD Ryzen 5600X.
RAM - Corsair Vengeance DDR4 8x2 16 GB.
PSU - Corsair RM750-750W Gold

Thank you for all your answers. I guess my best bet would be send the GPU to service under warranty. Do you want to add anything else?

take side panel of the case run a load on the card and see if the temperature changes if the temps change then you need a better case. with better airflow.

I did and it was only 2 degrees lower.

I did and it was only 2 degrees lower.

then i would say the card is defective
