Question GeForce RTX 3060 Ti overheats and stops sending signal to the monitor ?

[Cat with a hat]

I bought a second-hand pc 4 months ago with a GeForce RTX 3060 Ti and recently while gaming it stopped sending display signal to both my monitors. I still had audio, and the fans were still going but I couldn't interact with anything. Eventually the pc crashed and restarted, and after restarting everything now seems to be back to normal.

Later that day I benchmarked it with Cinebench and within 15 second it shot up to 85 to 90 degrees Celsius peaking at 92. I immediately stopped the program, and it quickly went but to an idle temperature of 44. The room I am in has bad ventilation but it was only 25 degrees Celsius in the room when I benchmarked.

This has been an ongoing issue and in the past I have installed 3 in fans and 3 out fans into my case as well as upgraded the CPU heatsink (as I the CPU was overheating previously but the new heatsink resolved this).

I am interested in advice on if there is anything I can do could do to lower the temp of the graphics card and stop the black screening.

specs:
CPU: intel i5-11400F
CPU cooler: Thermalright assassin x120 SE
Motherboard: B560m AORUS PRO
Bios is American Megatrends International, LLC. F9, 25/03/2022
Ram: 16Gb DDR4 Vulcan Z
SSD/HDD: WD-BLACK SN750 SE 500GB
GPU: GeForce RTX 3060 Ti
PSU: p650b gigabyte I don't exactly know how old it is because its second hand, but I presume 1-2 years (I will look into it)
Chassis: MATREXX 55 MESH ADD-RGB 4F
OS: windows 11 pro
Monitor: Msi G27C4 as my main and a random dell one as my secondary

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

The room I am in has bad ventilation but it was only 25 degrees Celsius in the room when I benchmarked.
That isn't a good thing. The PC innards will only be able to cool themselves if you feed the system with cooler, ambient air.

If the GPU is hitting past 83c (mostly for Nvidia cards) under any load and the fans are running very fast and loud, it either means the GPU is caked up with dust and pet hair, or if the GPU is not dirty, it more likely it means the thermal paste is no longer doing it's job between the GPU and the heatsink. The increasing fan RPM is one way the GPU tries to compensate for the increased temperature.

If the heatsink is not dirty, that means you will probably need to reapply thermal paste. It's usually not hard to do, but can be annoying if it's a RTX 3060 TI Founders Edition. The board partner cards usually only have around 8-12 screws to remove before you can slowly pull the heatsink off the board.

I am having this same issue on a RTX 3090 with it throttleing to 107c on the hot spot, then the screens turning off. I will be getting the thermal paste replaced in a few days...

Out of curiousity what games are you playing when you get the screens turning off?

Tell me how replacing the thermal past goes and if it fixes the problem because I am scared that I will break the gpu by opening it up.

I was playing satisfactory at 60 fps with high setting on a 1080p revolution.

The card is relatively clean as I cleaned it when I bought it so I think I will need to replace the thermal paste. Thanks

UPDATE: I repasted the card & the temps & blackscreen problems disappeared.

Thanks, I will try that.
What is the best thermal past that would ship to AU?
