Question [SOLVED] Cooling options for EVGA 2080 ti XC Ultra (Reference PCB) after fan failure

Hello everyone,
I recently built a new PC and I reused my EVGA 2080 ti XC Ultra from the older PC. Modo, CPU and everything else is new.

Everything is working fine except the GPU fans, that do not spin. The GPU itself is fine and it works. I have probably tried most of the common solutions I have seen around but nothing works. The fans of an older GPU (750 ti) spins fine in the new mobo but the 2080 ti fans no longer spin in both the old and new mobos. I have tried force-spin the fans as I use to do in my older PC with Afterburner or EVGA precision software, but nothing. Also tried some stress test with the same results. I presume that I have damaged either the fans or the fan controller when cleaning it before installing it in the new mobo. Fans are tightly connected and cables are not damaged. My guess is the small circuit where fans are connected, which I may have damaged when cleaning the card since I did not notice it was there.

Anyway, I do not want to mess around and I decided to just replace the whole cooling thing and I would like to ask for advice. What are my options? I have seen these AIO but I am not sure which one should I get. I have found the "official AIO" from EVGA but it is discontinued. My card has the reference PCB if that helps. I do not mind if the solution is expensive, just throw me everything you have. I do not have much experience in GPU so my preferred option would be something that involves a screw and some connectors, even if it is expensive.

Thank you for the video. This is something I could do and it does not seem very difficult.

A naive question. With this new fans, how are GPU temperatures monitored? Is it the same way as with the stock fans? I know they have sensors somewhere but I am not sure if they need the small circuit where the stock fans are attached to control that.

Welcome to the forums, newcomer!

Have you tried deshrouding the GPU and inspecting the make and model of the fans used on the GPU? Perhaps you can use Aliexpress or Ebay to hunt down a set of fans meant for the card?

Thank you for your help Lutfij!

While I cannot be 100% sure, I do not think the fans itself are faulty. I think it is the small circuit where the fans are connected. It is like small rectangular and flexible while plate with lots of stuff in there. It is facing the long side of the radiator. Sorry I cannot explain it better.

The temps should report the same as always but not control the fan speed.
Basically plug the fans into the motherboard and run them full speed all the time.
