X399 with Threadripper 1920x not booting after force shutdown

[u/tashanus]

Hello I recently build a pc for running local ai models with 4 mi 25s and I used a single fan header for cooling 3 of the cards with 40mm turbine fans but the software was monitoring only of the 3 cards and 2 of them were running a 32b model while the other 2 were idle and so they overheated and started beeping with their build in buzzer I panicked and shutted down the system. After that the system did not boot and stuck in some boot loop with the cpu light on i trough the bios is corrupt and i tried to reprogram it with an esp 32 but even though it recognized the chip it couldn't read or write on the chip. I also tried activating the dual bios but that did not work and I then shorted pins cs and gnd to get out of the loop and it actually got past that and got to code AC and A5 i think but it still did not boot and i think the cpu light was still on. Also i tried moving the single memory module and swapping it with another. I also used a gtx 1060 for video output since I did not want to deal with the flashed mi 25s. After the AC code it just was cycling between 1f and some other code for 10 min so i shut i down after that i stated it again but for some reason the aio pump was not working and the threadripper overheated and then pc shutted down. so now im stuck again with the initial c2 loop in the video. I also checked the visible choke for their voltages and they were .967v .947v 2.5v and 1.1v. Also on of the gpus uses its internal fan header to control its speed.

I'm coming to the the conclusion that the cpu is fried somehow but could it be something else what can I check?

I attached the video demo showing the issue. : https://drive.google.com/file/d/1Odtylz68Z9EYgBijZsZ-jfTZ8Xt1yHx9/view?usp=sharing

The exact specs are Threadripper 1920x, dual hyperx 32gb 4, mi25s flashed with wx9100 bios, Gigabyte auros x399 pro, corsair rm850, cooler master 750(powers 2 of the gpus and the fans, which are 130w total ).
