Question My GPU has a 105c hot spot temp when playing demanding games and my gpu temp is 80c

[lolkal1234561]

GPU: RTX 2080 TI Aorus

CPU: I7 7820x

CPU AIO Cooler: Cooler Master MasterLiquid Lite 240

Motherboard: X299 Aorus Ultra Gaming Pro

RAM: 16GB 3200 MHz DDR4 Memory

PSU: NZXT 650W + Gold Certified Fully Modular ATX Power Supply

Case: MSI MAG Forge 112R

One week ago i ordered a second hand 2080 ti from Cex. The thing is that when i play demanding games with it at ultra settings the gpu fans are very noisy, to the point that they reach 100% utilization. My previous GPU was an gtx 980 ti and its temperatures were about 84c. I dont kwon if the problem is about the case and its airflow or the gpu problem.

Can someone make me an idea of what is happening and why the gpu fans are so noisy?

The thermal paste may have dried up causing worse thermal transfer and therefore higher temps. (I understand that not everyone is comfortable taking apart their GPU to replace thermal paste, I certainly am not comfortable doing it, but maybe you could take it to a repair shop and have them do it.)

What's the gpu core at while hot spot is 105C?
FYI, approximately 20C or lower - it does vary between models - is the typical gap between the core and hot spot.
IF yours falls in that acceptable range, then it is more likely poor airflow.

By the way, what's the model of the 2080Ti?
Nevermind, I see it.

I dont know if the problem is about the case and its airflow or the gpu problem.

with the front & top mesh this case should allow for good airflow and heat dissipation.

unless the AIO is mounted/setup in an odd way it should allow for direct exhaust of CPU heated air.

maybe the included case fans just can't handle the necessary airflow and the GPU's heat is being somewhat recycled.
is the bottom/floor of the case also vented? if so, i would try adding a 4th intake on the middle or front of the PSU separator panel. this can lead the front-bottom fan's cool air intake directly to the GPU.
