Question RX 7800 XT rgb not working and fan speeds reading 0 rpm

[fakeplayer]

Hi, here is the story:

Yesterday I installed new Lian Li Uni fans 3pack with a controller. This GPU is massive and rests on top of the lower connector, like usb and fan connectors on MB etc.

Lian li 3pin rgb header is bit higher but with a tiny bend to rgb cable(not GPU), still managed to put in GPU quite easily. Before i did any cable management, i left it there, turn on PC and all the fans/lights worked, so did the rx 7800 xt light strip.

So, i unhooked everything again to route it properly and so on, but second time, while Lian li fans still worked fine, GPU lights stoped working. And on top of it - it doesnt give any fan speed readings on software like Adrenaline or L-Connect 3 etc.

GPU itself works, MB recognizes it, fans also spin when its getting hotter.

So far I reinstalled driver using DDU, tried putting in GPU again, pushing PSU connectors snug, reinstalled Trixx and LConnect software, even unhooked all the new fan system, but same issue. Have I killed my GPU somehow by handling it, shorted it or something?
